I have a simple Delimited log file. I`m using FileHelper library to parse the file using the following code:
LogLine record;
FileHelperAsyncEngine<LogLines> engine = new FileHelperAsyncEngine<LogLines>();
engine.BeginReadFile(#"C:\logs\Log.log");
while (engine.ReadNext() != null)
{
record = engine.LastRecord;
//record.Reported = true; <---I want to be able to edit this!
// Your Code Here
}
Is there any way I can edit this record?
Will something like this be fine for you?
This will modify second element of that file; could not find method similar to seek for that class.
public static void WriteExample()
{
FileHelperEngine engine = new FileHelperEngine(typeof(SampleType));
// to Read use:
SampleType[] res = engine.ReadFile("source.txt") as SampleType[];
res[1].Field1 = "test";
res[1].Field2 = 9;
// to Write use:
engine.WriteFile("source2.txt", res);
}

I decided to get into coding and am learning c#, after making a few small projects, I decided to step it up a little and make a text adventure game, with saving and loading, and if I get to feeling zany I'll try to add some multiplayer. While I haven't really hit a road block because of it, I can't help but feel that I am doing load function REALLY sub-optimally. The save is fine, I feel like it works for me, but the load I feel can be really simplified, I just don't know what to use.
I also wouldn't really mind, but with this way, if I add other attributes/skills or whatever else that needs to be saved, I will have to add everything to the load function as well, and it will be even longer.
I have tried to search around on here, the c# documentation, and other sites, but can't find a solution that works for this case. can anyone help me find a better way of doing this? Or is this the best I can really do since it's varying data types?
Edit: To simplify and clarify what answer I am searching for, I am trying to find a simpler and more scalable way to save and load the data to a file.
static void LoadGame(CharData PlayerData)
{
Console.WriteLine("Enter the name of the character to load as shown below.");
//getting current directory info, setting to di
DirectoryInfo di = new DirectoryInfo(Directory.GetCurrentDirectory());
//need to initialize these outside of a loop
int SaveFiles = 0;
string DisplayName = " ";
int DisplayNameLength = 0;
//looks through files in working directory ending in '.fasv', displays them in format '{x}. John Smith'
foreach (var fi in di.GetFiles("*.fasv"))
{
SaveFiles++;
DisplayNameLength = fi.Name.Length;
//remove .fasv from displayed name to make it look nicer
DisplayName = fi.Name.Remove(DisplayNameLength - 5, 5);
Console.WriteLine(SaveFiles.ToString() + ". " + DisplayName);
}
string toLoad = Console.ReadLine();
using StreamReader sr = new StreamReader(toLoad + ".fasv");
//the name is easy to get since it's a string. but integers...
PlayerData.Name = sr.ReadLine();
//... not so much. i hate all of this and i feel like it's gross, but i don't know how else to do it
int hp, xp, level, toughness, innovation, mind, empathy, spryness;
Int32.TryParse(sr.ReadLine(), out hp);
Int32.TryParse(sr.ReadLine(), out xp);
Int32.TryParse(sr.ReadLine(), out level);
Int32.TryParse(sr.ReadLine(), out toughness);
Int32.TryParse(sr.ReadLine(), out innovation);
Int32.TryParse(sr.ReadLine(), out mind);
Int32.TryParse(sr.ReadLine(), out empathy);
Int32.TryParse(sr.ReadLine(), out spryness);
PlayerData.Health = hp;
PlayerData.Level = level;
PlayerData.XP = xp;
PlayerData.Toughness = toughness;
PlayerData.Innovation = innovation;
PlayerData.Mind = mind;
PlayerData.Empathy = empathy;
PlayerData.Spryness = spryness;
sr.Close();
InGame(PlayerData);
}
static void SaveGame(CharData PlayerData)
{
using (StreamWriter sw = new StreamWriter(PlayerData.Name + ".fasv"))
{
foreach (System.Reflection.PropertyInfo stat in PlayerData.GetType().GetProperties())
{
//write player data properties to file line by line, using stat to iterate through the player data properties
sw.WriteLine(stat.GetValue(PlayerData));
}
sw.Close();
}
}
If you aren't set on a particular data format for the file data, I would recommend using a serializer such as JSON.NET. You can use NuGet to add newtonsoft.json to your project, and that would allow you to just do something similar to:
using (StreamWriter file = File.CreateText(pathToPlayerFile))
{
var serializer = new JsonSerializer();
serializer.Serialize(file, playerData);
}
And then your code to read from the file would be pretty similar:
using (var file = File.OpenText(pathToPlayerFile))
{
var serializer = new JsonSerializer();
return (CharData)serializer.Deserialize(file, typeof(CharData));
}
I borrowed those code snippets from newtonsoft.com. CreateText will create (or overwrite) the file and write the object as a JSON object.
I must use a text file "db.txt" which inherits the names of the Server and Database to make my connection string complete.
db.txt looks like this:
<Anfang>
SERVER==dbServer\SQLEXPRESS
DATABASE==studentweb
<Ende>
The connection string:
string constr = ConfigurationManager.ConnectionStrings["DRIVER={SQL Server}; SERVER=SERVER DATABASE=DB UID=;PWD=;LANGUAGE=Deutsch;Trusted_Connection=YES"].ConnectionString;
Unfortunatly we are only allowed to use Classic ASPX.net (C# 2.0) and not the web.config.
I've searched a lot, but found nothing close to help me.
Somebody got an Idea how to make it work?
Here is something to get you going.
In a nutshell, I put the DBInfo file through a method that reads the file line by line. When I see the line <anfang> I know the next line will be important, and when I see the line <ende> I know it's the end, so I need to grab everything in between. Hence why I came up with the booleans areWeThereYet and isItDoneYet which I use to start and stop gathering data from the file.
In this snippet I use a Dictionary<string, string> to store and return the values but, you could use something different. At first I was going to create a custom class that would hold all the DB information but, since this is a school assignment, we'll go step by step and start by using what's already available.
using System;
using System.Collections.Generic;
namespace _41167195
{
class Program
{
static void Main(string[] args)
{
string pathToDBINfoFile = #"M:\StackOverflowQuestionsAndAnswers\41167195\41167195\sample\DBInfo.txt";//the path to the file holding the info
Dictionary<string, string> connStringValues = DoIt(pathToDBINfoFile);//Get the values from the file using a method that returns a dictionary
string serverValue = connStringValues["SERVER"];//just for you to see what the results are
string dbValue = connStringValues["DATABASE"];//just for you to see what the results are
//Now you can adjust the line below using the stuff you got from above.
//string constr = ConfigurationManager.ConnectionStrings["DRIVER={SQL Server}; SERVER=SERVER DATABASE=DB UID=;PWD=;LANGUAGE=Deutsch;Trusted_Connection=YES"].ConnectionString;
}
private static Dictionary<string, string> DoIt(string incomingDBInfoPath)
{
Dictionary<string, string> retVal = new Dictionary<string, string>();//initialize a dictionary, this will be our return value
using (System.IO.StreamReader sr = new System.IO.StreamReader(incomingDBInfoPath))
{
string currentLine = string.Empty;
bool areWeThereYet = false;
bool isItDoneYet = false;
while ((currentLine = sr.ReadLine()) != null)//while there is something to read
{
if (currentLine.ToLower() == "<anfang>")
{
areWeThereYet = true;
continue;//force the while to go into the next iteration
}
else if (currentLine.ToLower() == "<ende>")
{
isItDoneYet = true;
}
if (areWeThereYet && !isItDoneYet)
{
string[] bleh = currentLine.Split(new string[] { "==" }, StringSplitOptions.RemoveEmptyEntries);
retVal.Add(bleh[0], bleh[1]);//add the value to the dictionary
}
else if (isItDoneYet)
{
break;//we are done, get out of here
}
else
{
continue;//we don't need this line
}
}
}
return retVal;
}
}
}
I'm using C# Code in Ranorex 5.4.2 to create a CSV file, have data gathered from an XML file and then have it write this into the CSV file. I've managed to get this process to work but I'm experiencing an issue where there are 12 blank lines created beneath the gathered data.
I have a file called CreateCSVFile which creates the CSV file and adds the headers in, the code looks like this:
writer.WriteLine("PolicyNumber,Surname,Postcode,HouseNumber,StreetName,CityName,CountyName,VehicleRegistrationPlate,VehicleMake,VehicleModel,VehicleType,DateRegistered,ABICode");
writer.WriteLine("");
writer.Flush();
writer.Close();
The next one to run is MineDataFromOutputXML. The program I am automating provides insurance quotes and an output xml file is created containing the clients details. I've set up a mining process which has a variable declared at the top which shows as:
string _PolicyHolderSurname = "";
[TestVariable("3E92E370-F960-477B-853A-0F61BEA62B7B")]
public string PolicyHolderSurname
{
get { return _PolicyHolderSurname; }
set { _PolicyHolderSurname = value; }
}
and then there is another section of code which gathers the information from the XML file:
var QuotePolicyHolderSurname = (XmlElement)xmlDoc.SelectSingleNode("//cipSurname");
string QuotePolicyHolderSurnameAsString = QuotePolicyHolderSurname.InnerText.ToString();
PolicyHolderSurname = QuotePolicyHolderSurnameAsString;
Report.Info( "Policy Holder Surname As String = " + QuotePolicyHolderSurnameAsString);
Report.Info( "Quote Policy Holder Surname = " + QuotePolicyHolderSurname.InnerText);
The final file is called SetDataSource and it puts the information into the CSV file, there is a variable declared at the top like this:
string _PolicyHolderSurname = "";
[TestVariable("222D47D2-6F66-4F05-BDAF-7D3B9D335647")]
public string PolicyHolderSurname
{
get { return _PolicyHolderSurname; }
set { _PolicyHolderSurname = value; }
}
This is then the code that adds it into the CSV file:
string Surname = PolicyHolderSurname;
Report.Info("Surname = " + Surname);
dataConn.Rows.Add(new string[] { Surname });
dataConn.Store();
There are multiple items in the Mine and SetDataSource files and the output looks like this in Notepad++:
Picture showing the CSV file after the code has been run
I believe the problem lies in the CreateCSVFile and the writer.WriteLine function. I have commented this region out but it then produces the CSV with just the headers showing.
I've asked some of the developers I work with but most don't know C# very well and no one has been able to solve this issue yet. If it makes a difference this is on Windows Server 2012r2.
Any questions about this please ask, I can provide the whole files if needed, they're just quite long and repetitive.
Thanks

I had the exact same thing to do in Ranorex. Since the question is a bit old I didn't checked your code but here is what I did and is working. I found an example (probably on stack) creating a csv file in C#, so here is my adaptation for using in Ranorex UserCodeCollection:
[UserCodeCollection]
public class UserCodeCollectionDemo
{
[UserCodeMethod]
public static void ConvertXmlToCsv()
{
System.IO.File.Delete("E:\\Ranorex_test.csv");
XDocument doc = XDocument.Load("E:\\lang.xml");
string csvOut = string.Empty;
StringBuilder sColumnString = new StringBuilder(50000);
StringBuilder sDataString = new StringBuilder(50000);
foreach (XElement node in doc.Descendants(GetServerLanguage()))
{
foreach (XElement categoryNode in node.Elements())
{
foreach (XElement innerNode in categoryNode.Elements())
{
//"{0}," give you the output in Comma seperated format.
string sNodePath = categoryNode.Name + "_" + innerNode.Name;
sColumnString.AppendFormat("{0},", sNodePath);
sDataString.AppendFormat("{0},", innerNode.Value);
}
}
}
if ((sColumnString.Length > 1) && (sDataString.Length > 1))
{
sColumnString.Remove(sColumnString.Length-1, 1);
sDataString.Remove(sDataString.Length-1, 1);
}
string[] lines = { sColumnString.ToString(), sDataString.ToString() };
System.IO.File.WriteAllLines(#"E:\Ranorex_test.csv", lines);
}
}

I am new to SSIS and C#. In SQL Server 2008 I am importing data from a .csv file. Now I have the columns dynamic. They can be around 22 columns(some times more or less). I created a staging table with 25 columns and import data into it. In essence each flat file that I import has different number of columns. They are all properly formatted only. My task is to import all the rows from a .csv flat file including the headers. I want to put this in a job so I can import multiple files into the table daily.
So inside a for each loop I have a data flow task within which I have a script component. I came up(research online) with the C# code below but I get error:
Index was outside the bounds of the array.
I tried to find the cause using MessageBox and I found it is reading the first line and the index is going outside the bounds of the array after the first line.
1.) I need your help with fixing the code
2.) My File1Conn is the flat file connection instead I want to read it directly from a variable User::FileName that my foreach loop keeps updating. Please help with modifying the code below.
Thanks in advance.
This is my flat file:

As you mentioned the file has dynamic amount of columns, in your script component you need to count number of columns by delimiters, then redirect to different outputs.
For your 2nd question, you can assign your variable to the flat file connection manager connection string property. Then you can read the variable value in your script directly.
Except for script component, you can create a "one column" flat file source by using a dummy delimiter, then in the data flow task, you can read amount of columns into a variable, conditional split the data flow, redirect the outputs into different destinations. An example can be found at http://sqlcodespace.blogspot.com.au/2015/03/ssis-design-pattern-handling-flat-file.html
I have downloaded a dictionary file from http://code.google.com/p/quickdic-dictionary/
But the file extension is .quickdic and is not plain text.
How can I load the quickdic dictionaries (.quickdic) into c# to make simple word queries?
I browsed through the git code, and a few things stuck out.
First, in the DictionaryActivity.java file, there is the following in onCreate():
final String name = application.getDictionaryName(dictFile.getName());
this.setTitle("QuickDic: " + name);
dictRaf = new RandomAccessFile(dictFile, "r");
dictionary = new Dictionary(dictRaf);
That Dictionary Class is not the built in class with Java, but is here according to the imports:
import com.hughes.android.dictionary.engine.Dictionary;
When I look there, it shows a constructor for a Dictionary taking a RandomAccessFile as the parameter. Here's that source code:
public Dictionary(final RandomAccessFile raf) throws IOException {
dictFileVersion = raf.readInt();
if (dictFileVersion < 0 || dictFileVersion > CURRENT_DICT_VERSION) {
throw new IOException("Invalid dictionary version: " + dictFileVersion);
}
creationMillis = raf.readLong();
dictInfo = raf.readUTF();
// Load the sources, then seek past them, because reading them later disrupts the offset.
try {
final RAFList<EntrySource> rafSources = RAFList.create(raf, new EntrySource.Serializer(this), raf.getFilePointer());
sources = new ArrayList<EntrySource>(rafSources);
raf.seek(rafSources.getEndOffset());
pairEntries = CachingList.create(RAFList.create(raf, new PairEntry.Serializer(this), raf.getFilePointer()), CACHE_SIZE);
textEntries = CachingList.create(RAFList.create(raf, new TextEntry.Serializer(this), raf.getFilePointer()), CACHE_SIZE);
if (dictFileVersion >= 5) {
htmlEntries = CachingList.create(RAFList.create(raf, new HtmlEntry.Serializer(this), raf.getFilePointer()), CACHE_SIZE);
} else {
htmlEntries = Collections.emptyList();
}
indices = CachingList.createFullyCached(RAFList.create(raf, indexSerializer, raf.getFilePointer()));
} catch (RuntimeException e) {
final IOException ioe = new IOException("RuntimeException loading dictionary");
ioe.initCause(e);
throw ioe;
}
final String end = raf.readUTF();
if (!end.equals(END_OF_DICTIONARY)) {
throw new IOException("Dictionary seems corrupt: " + end);
}
So, anyway, this is how his java code reads the file in.
Hopefully, this helps you simulate this in C#.
From here you would probably want to see how he is serializing the EntrySource, PairEntry, TextEntry, and HtmlEntry, as well as the indexSerializer.
Next look to see how RAFList.create() works.
Then see how that result is incorporated in creating a CachingList using CachingList.create()
Disclaimer: I'm not sure if the built in serializer in C# uses the same format as Java's, so you may need to simulate that too :)
