How to extract specific string from a text?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Newtonsoft.Json;
namespace Rename_Files
{
public partial class Form1 : Form
{
string[] files;
public Form1()
{
InitializeComponent();
files = Directory.GetFiles(#"C:\Program Files (x86)\Steam\steamapps\common\King's Quest\Binaries\Win\Saved Games", "*.*", SearchOption.AllDirectories);
for(int i = 2; i < files.Length; i++)
{
string text = File.ReadAllText(files[i]);
int startPos = text.IndexOf("currentLevelName");
int length = text.IndexOf("currentLevelEntryDirection") - 3;
string sub = text.Substring(startPos, length);
}
}
private void Form1_Load(object sender, EventArgs e)
{
}
}
}
The part i want to extract is :
currentLevelName":"E1_WL1_FindBow_M","currentLevelEntryDirection"
This is a part of the file content :
m_ItemsEncodedJsons ArrayProperty None ! m_WhatLevelPlayerIsAtEncodedJson ArrayProperty O G {"currentLevelName":"E1_WL1_FindBow_M","currentLevelEntryDirection":8} & m_WhatCheckPointPlay
the way i'm trying now i'm getting exception because
System.ArgumentOutOfRangeException: 'Index and length must refer to a location within the string.
Parameter name: length'
startPos value is : 1613 and the value of length is 1653
so the exception is logic but i'm not sure yet how to extract the specific string out of the text.
Update :
this is almost working :
int startPos = text.IndexOf("currentLevelName");
int length = text.IndexOf("currentLevelEntryDirection");
string sub = text.Substring(startPos, length - startPos);
the result in sub is :
"currentLevelName\":\"E1_WL1_HangingBedsA_M\",\""
but i want that sub will contain this :
currentLevelName"E1_WL1_HangingBedsA_M\"
optional without the two "" either and maybe to add _
currentLevelName_"E1_WL1_HangingBedsA_M\"
or
currentLevelName_E1_WL1_HangingBedsA_M\

The problem you are facing is indeed this one:
How to extract the content with specific pattern from a String?
In this case, you can use Regular Expression to extract the content you want.
Given the following text:
m_ItemsEncodedJsons ArrayProperty None ! m_WhatLevelPlayerIsAtEncodedJson ArrayProperty O G {"currentLevelName":"E1_WL1_FindBow_M","currentLevelEntryDirection":8} & m_WhatCheckPointPlay
By using this Regex pattern:
string pattern = #"""currentLevelName"":"".*"",""currentLevelEntryDirection"":\d+";
You will be able to extract the following content:
"currentLevelName":"E1_WL1_FindBow_M","currentLevelEntryDirection":8
Here is the code snippet in C#:
using System;
using System.Text.RegularExpressions;
public class Example
{
public static void Main()
{
// this is the original text
string input = #"m_ItemsEncodedJsons ArrayProperty None ! m_WhatLevelPlayerIsAtEncodedJson ArrayProperty O G {""currentLevelName"":""E1_WL1_FindBow_M"",""currentLevelEntryDirection"":8} & m_WhatCheckPointPlay";
// this is the pattern you are looking for
string pattern = #"""currentLevelName"":"".*"",""currentLevelEntryDirection"":\d+";
RegexOptions options = RegexOptions.Multiline;
foreach (Match m in Regex.Matches(input, pattern, options))
{
Console.WriteLine("'{0}' found at index {1}.", m.Value, m.Index);
}
}
}
One of the reasons you should use Regex in this case is that, if the value of currentLevelEntryDirection is not single-digit, e.g. 8123, the above code snippet can still be able to extract the correct value.
You can also find the above example and edit it here: https://regex101.com/r/W4ihuk/3
Furthermore, you can extract the property names and values by using capturing group. For example:
string pattern = #"""(currentLevelName)"":""(.*)"",""(currentLevelEntryDirection)"":(\d+)";
You can extract the following data:
currentLevelName, E1_WL1_FindBow_M, currentLevelEntryDirection, 8 and you can get the values by looping all the Match objects.

it seems the content is separated by a space delimiter. and the positions are fixed.
If so, you could do something like :
var splitted = text.Split(' ');
var json = splitted[8]; // this is the json part in the content;
However, since we don't know wither the content might change or not. You can still use this :
var startPos = text.IndexOf('{');
var endPos = text.IndexOf('}') + 1;
var json = text.Substring(startPos, endPos - startPos);
This would extract the Json part of the file. Now, you can implement a json model that will be used to deserialize this json like this :
using System.Text.Json;
using System.Text.Json.Serialization;
public class JsonModel
{
[JsonPropertyName("currentLevelName")]
public string? CurrentLevelName { get; set; }
[JsonPropertyName("currentLevelEntryDirection")]
public int CurrentLevelEntryDirection { get; set; }
}
With that we can do :
var result = JsonSerializer.Deserialize<JsonModel>(json);
var leveName = result.CurrentLevelName;

private string FindCurrentLevelName(string MyString)
{
var FirstSplit = MyString.Split(new char[] { '{' },
StringSplitOptions.RemoveEmptyEntries);
if (FirstSplit.Length != 2)
{
return "";
}
var SecondSplit = FirstSplit[1].Split(new char[] { '}' },
StringSplitOptions.RemoveEmptyEntries);
if (SecondSplit.Length != 2)
{
return "";
}
var FinalSplit = SecondSplit[0].Split(new char[] { '"' },
StringSplitOptions.RemoveEmptyEntries);
if (FinalSplit.Length != 6)
{
return "";
}
return FinalSplit[2];
}

To get the specific string pattern in a non-JSON format data string
Use the regex to get the stirng and operate it will be good I thought.
By using the regex pattern: "currentLevelName":"\w+"
in your example content, your will get: "currentLevelName":"E1_WL1_HangingBedsA_M"
Then use the result to create or replace your file name.
the code below will get the savedGame001.txt's content and extract the currentLevelName block, then create a new file whcih the name is in this format: [filename]_[theCurrentLevelName]
using System.Text.RegularExpressions;
// your file path
string filePath = #"C:\Users\a0204\Downloads";
// your file name
string fileName = #"savedGame001.txt";
// read file content
string stringContent = string.Empty;
stringContent = System.IO.File.ReadAllText(filePath + "\\" + fileName);
// Get the mathced string By regex => "currentLevelName":"\w+"
var regex = new Regex("\"currentLevelName\":\"\\w+\"");
Match matched = regex.Match(stringContent);
string matchedString = matched.Value;
// Get the string below the colon
int colonPosition = matchedString.IndexOf(":");
string value = matchedString.Substring(colonPosition + 1);
value = value.Replace("\"", string.Empty);
// remove the .txt and add the matched string to file name
fileName = fileName.Remove(fileName.Length - 4, 4);
string newFileName = fileName + "_" + value;
// check the new file name
Console.WriteLine(newFileName);
// write content to new file name
FileStream fileStream = File.Create(filePath + "\\" + newFileName);
fileStream.Dispose();
File.WriteAllText(filePath + "\\" + newFileName, stringContent);
Console.ReadLine();

I have this flat file and I need to group this based on the 2nd position to 8th position
example(2739158/3180826/3292015) and write to another flat file.
So the data Starting with 'E' should Repeat in the single line along with that group field(2nd to 8th Position in the start) and I should take the 9th Position after 'E'
Also I need to replace Empty space with ('*' star)
For example
1st Line

Can we do this in Stream reader c#, please?
Any help would be highly appreciated.The file size is more than 285 MB so it it good to read through Stream Reader?
Thanks

Taking multiple substrings from a single line in a .txt file in C#

Part of a class assignment I'm working on requires me to take isolate certain parts of a "students" info from a .txt file such as last name, first name, and gpa. While I can get the last name to appear properly, going beyond that is iffy, first names will be cut off or go to the middle initial seemingly randomly. I need help with having consistent cut off points based on markers (apostrophes) in the lines.
this is a sample of the .txt file Students2 which is located in the program's Bin Debug
(LIST (LIST 'Abbott 'Ashley 'J ) '8697387888 'ajabbott#mail.usi.edu 2.3073320999676614 )
(LIST (LIST 'Abbott 'Bradley 'M ) 'NONE 'bmabbott#mail.usi.edu 3.1915725161177115 )
(LIST (LIST 'Abbott 'Ryan 'T ) '8698689793 'rtabbott#mail.usi.edu 3.448215586562192 )
(LIST (LIST 'Abel 'Heather 'M ) '8698689386 'hmabel#mail.usi.edu 3.2517764202656974 )
Hopefully what I meant by markers makes sense, and the info is fake if anyone wondered.
The following is my current code, some of which was provided in an example.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
namespace ConsoleApplication61
{
class Program
{
static void Main(string[] args)
{
StreamReader inFile;
string inLine;
if (File.Exists("Students2.txt"))
{
try
{
using (StreamWriter Malachi = File.AppendText("Students2.txt"))
{
Malachi.WriteLine("(LIST (LIST 'Constant 'Malachi 'J ) '1832878847 'mconstant#mail.usi.edu 4.0000000000000000 )");
}
inFile = new StreamReader("Students2.txt");
while ((inLine = inFile.ReadLine()) != null)
{
int start = inLine.IndexOf("'");
if (start >= 0)
{
inLine = inLine.Substring(start);
int end = inLine.IndexOf(" ");
string lastname = inLine.Substring(0, end);
int endTwo = inLine.IndexOf(" ");
string firstname = inLine.Substring(end, endTwo);
int endThree = inLine.IndexOf(" ");
string email = inLine.Substring(endTwo, endThree);
Console.WriteLine( lastname + firstname );
}
}
}
catch (System.IO.IOException exc)
{
Console.WriteLine("Error");
}
}
}
}
}
Again I'd like to know what I'm doing wrong in regards to cutting off at specific points. Any and all help is greatly appreciated.

you can use the split function and replace function to get what you are looking for something like this
string test = "(LIST (LIST 'Constant 'Malachi 'J ) '1832878847 'mconstant#mail.usi.edu 4.0000000000000000 )";
test = test.Replace(")","");
string[] abc = test.Split(new string[] { "'" }, StringSplitOptions.None);
Console.WriteLine("Last Name =" + abc[1]);
Console.WriteLine("First Name =" + abc[2]);
Console.WriteLine("Middle Initial =" + abc[3]);
Console.WriteLine("Email gpa =" + abc[abc.Length-1]);
UPDATE
In case there is no apostrophe for gpa you can get those values as below, just replace the last line with this
Console.WriteLine("Email =" + (abc[abc.Length-1]).Split(' ')[0]);
Console.WriteLine("gpa =" + (abc[abc.Length-1]).Split(' ')[1]);
Here is a fiddle for it https://dotnetfiddle.net/vJYLXW

you need to update inLine every time you take off substring like -
int start = inLine.IndexOf("'");
if (start >= 0)
{
inLine = inLine.Substring(start);
int end = inLine.IndexOf(" ");
string lastname = inLine.Substring(0, end);
inLine = inLine.Substring(end + 1);
int endTwo = inLine.IndexOf(" ");
string firstname = inLine.Substring(end, endTwo);
inLine = inLine.Substring(endTwo + 1);
int endThree = inLine.IndexOf(" ");
string email = inLine.Substring(endTwo, endThree);
.
.
}
and so on.....
OR you take find next space after end point of first string like this -
int start = inLine.IndexOf("'");
if (start >= 0)
{
inLine = inLine.Substring(start);
int end = inLine.IndexOf(" ");
string lastname = inLine.Substring(0, end);
int endTwo = inLine.IndexOf(' ', end + 1);
string firstname = inLine.Substring(end, endTwo - end);
int endThree = inLine.IndexOf(' ', endTwo + 1);
string middleinitial = inLine.Substring(endTwo, endThree - endTwo);
endThree += 2; // to escape ')' after middle initial
int endFour = inLine.IndexOf(' ', endThree + 1);
string phone = inLine.Substring(endThree, endFour - endThree);
int endFive = inLine.IndexOf(' ', endFour + 1);
string email = inLine.Substring(endFour, endFive - endFour);
int endSix = inLine.IndexOf(' ', endFive + 1);
string gpa = inLine.Substring(endFive, endSix - endFive);
Console.WriteLine("Last Name - " + lastname);
Console.WriteLine("First Name - " + firstname);
Console.WriteLine("Middle Initial - " + middleinitial);
Console.WriteLine("Phone - " + phone);
Console.WriteLine("Email - " + email);
Console.WriteLine("GPA - " + gpa);
}
But I would recommend string split option. Read about String.Split Method
while ((inLine = inFile.ReadLine()) != null)
{
var splits = inLine.Split(new[] { ' ', '\'' }, StringSplitOptions.RemoveEmptyEntries);
if (splits.Length > 0)
{
Console.WriteLine("Last Name - " + splits[2]);
Console.WriteLine("First Name - " + splits[3]);
Console.WriteLine("Middle Initial - " + splits[4]);
Console.WriteLine("Phone - " + splits[6]);
Console.WriteLine("Email - " + splits[7]);
Console.WriteLine("GPA - " + splits[8]);
}
Console.WriteLine("------------------------------------------------------");
}

It is much easier to get the desired fields with regexp:
Regex rPattern= new Regex(#"\'([^'\s]+)[\'\s]+([^'\s]+)[\'\s]+([^'\s]+)[\'\s]+\)[\'\s]+([^'\s]+)[\'\s]+([^'\s]+)[\'\s]+([^'\s]+)");
....
Match m = rPattern.Match(inLine );
if(m.Success)
{
string lastname = m.Groups[1].Value;
string firstname = m.Groups[2].Value;
string middlename = m.Groups[3].Value;
string phone = m.Groups[4].Value;
string email = m.Groups[5].Value;
string somenumber = m.Groups[6].Value;
}
Your code can be something like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
//PTK: don't forget include following line. IT'S IMPORTANT !!!
using System.Text.RegularExpressions;
namespace ConsoleApplication61
{
class Program
{
static void Main(string[] args)
{
StreamReader inFile;
string inLine;
//PTK: patern for your fields
Regex rPattern= new Regex(#"\'([^'\s]+)[\'\s]+([^'\s]+)[\'\s]+([^'\s]+)[\'\s]+\)[\'\s]+([^'\s]+)[\'\s]+([^'\s]+)[\'\s]+([^'\s]+)");
if (File.Exists("Students2.txt"))
{
try
{
using (StreamWriter Malachi = File.AppendText("Students2.txt"))
{
Malachi.WriteLine("(LIST (LIST 'Constant 'Malachi 'J ) '1832878847 'mconstant#mail.usi.edu 4.0000000000000000 )");
}
inFile = new StreamReader("Students2.txt");
while ((inLine = inFile.ReadLine()) != null)
{
//PTK: match the current line with the pattern
Match m = rPattern.Match(inLine );
if(m.Success)
{
string lastname = m.Groups[1].Value;
string firstname = m.Groups[2].Value;
string middlename = m.Groups[3].Value;
string phone = m.Groups[4].Value;
string email = m.Groups[5].Value;
string somenumber = m.Groups[6].Value;
Console.WriteLine( lastname + firstname );
}
}
}
catch (System.IO.IOException exc)
{
Console.WriteLine("Error");
}
}
}
}
}

Change the name of headers in CSV file using CSVHelper in C#

I am using CSV Helper library to produce CSV files for the user to
to populate and upload into the system. My issue is that the WriteHeader method just writes the attributes of a class with names like "PropertyValue", which is not user friendly. Is there a method I can use to make the text produced user friendly but is still able to successfully map the class to the files data?
My code looks like the following:
public ActionResult UploadPropertyCSV(HttpPostedFileBase file)
{
List<PropertyModel> properties = new List<PropertyModel>();
RIMEDb dbContext = new RIMEDb();
bool success = false;
foreach (string requestFiles in Request.Files)
{
if (file != null && file.ContentLength > 0 && file.FileName.EndsWith(".csv"))
{
using(StreamReader str = new StreamReader(file.InputStream))
{
using(CsvHelper.CsvReader theReader = new CsvHelper.CsvReader(str))
{
while (theReader.Read())
{
RIMUtil.PropertyUploadCSVRowHelper row = new RIMUtil.PropertyUploadCSVRowHelper()
{
UnitNumber = theReader.GetField(0),
StreetNumber = theReader.GetField(1),
StreetName = theReader.GetField(2),
AlternateAddress = theReader.GetField(3),
City = theReader.GetField(4)
};
Property property = new Property();
property.UnitNumber = row.UnitNumber;
property.StreetNumber = row.StreetNumber;
property.StreetName = row.StreetName;
property.AlternateAddress = row.AlternateAddress;
property.City = dbContext.PostalCodes.Where(p => p.PostalCode1 == row.PostalCode).FirstOrDefault().City;
dbContext.Properties.Add(property);
try
{
dbContext.SaveChanges();
success = true;
}
catch(System.Data.Entity.Validation.DbEntityValidationException ex)
{
success = false;
RIMUtil.LogError("Ptoblem validating fields in database. Please check your CSV file for errors.");
}
catch(Exception e)
{
RIMUtil.LogError("Error saving property to database. Please check your CSV file for errors.");
}
}
}
}
}
}
return Json(success);
}
I'm wondering if theres some metadata tag or something I can put on top of each attribute in my PropertyUploadCSVRowHelper class to put the text I want produced in the file
Thanks in advance

Not sure if this existed 2 years ago but now, we can change the property/column name by using the following attribute function:
[CsvHelper.Configuration.Attributes.Name("Column/Field Name")]
Full code:
using CsvHelper;
using System.Collections.Generic;
using System.IO;
namespace Test
{
class Program
{
class CsvColumns
{
private string column_01;
[CsvHelper.Configuration.Attributes.Name("Column 01")] // changes header/column name Column_01 to Column 01
public string Column_01 { get => column_01; set => column_01 = value; }
}
static void Main(string[] args)
{
List<CsvColumns> csvOutput = new List<CsvColumns>();
CsvColumns rows = new CsvColumns();
rows.Column_01 = "data1";
csvOutput.Add(rows);
string filename = "test.csv";
using (StreamWriter writer = File.CreateText(filename))
{
CsvWriter csv = new CsvWriter(writer);
csv.WriteRecords(csvOutput);
}
}
}
}

This might not be answering your question directly as you said you wanted to use csvhelper, but if you're only writing small size files (this is a simple function that I use to generate csv. Note, csvhelper will be much better for larger files as this is just building a string and not streaming the data.
Just customise the columns array in the code below variable to suit your needs.
public string GetCsv(string[] columns, List<object[]> data)
{
StringBuilder CsvData = new StringBuilder();
//add column headers
string[] s = new string[columns.Length];
for (Int32 j = 0; j < columns.Length; j++)
{
s[j] = columns[j];
if (s[j].Contains("\"")) //replace " with ""
s[j].Replace("\"", "\"\"");
if (s[j].Contains("\"") || s[j].Contains(" ")) //add "'s around any string with space or "
s[j] = "\"" + s[j] + "\"";
}
CsvData.AppendLine(string.Join(",", s));
//add rows
foreach (var row in data)
{
for (int j = 0; j < columns.Length; j++)
{
s[j] = row[j] == null ? "" : row[j].ToString();
if (s[j].Contains("\"")) //replace " with ""
s[j].Replace("\"", "\"\"");
if (s[j].Contains("\"") || s[j].Contains(" ")) //add "'s around any string with space or "
s[j] = "\"" + s[j] + "\"";
}
CsvData.AppendLine(string.Join(",", s));
}
return CsvData.ToString();
}

I have this, and i want to serialize to xml both lists :
List<Empleados> emp = new List<Empleados>();
List<Agenda> agen = new List<Agenda>();
I used SerializeToXML method that i found in other tutorial but when i run it an error shows up
"Error 1 Inconsistent accessibility: parameter type
'System.Collections.Generic.List' is less accessible
than method
'AppPrueba.Form1.SerializeToXML(System.Collections.Generic.List)' C:\Users\722825\Desktop\Santi
Cosas\AppPrueba\AppPrueba\Form1.cs 27 28 AppPrueba"
Thanks in advance if you can help me!

All the classes that you are trying to serialize to xml should be public. And for collection serialization you cannot use generics - either use untyped collections, like, ArrayList , or create a non-generic descendant class form List .

agen is private and SerializeToXML is public static. You need agen public

Your error says that the variabel List agen = new List(); needs to be public like this: public List agen = new List();
