I found application that use .txt files as config files.
The Files looks like
[[plugin.save]]=[[Save]]
how do I use it in C#?
how can I read The file to my application to use Values in [] as config?
You have to read it as a regular file. Reading it use Dictionary to store values.
Example code:
Dictionary<string, string> configuration = new Dictionary<string, string>();
Regex r = new Regex(#"\[\[(\w+)\]\]=\[\[(\w+)\]\]");
string[] configArray = {"[[param1]]=[[Value1]]", "[[param2]]=[[Value2]]"};// File.ReadAllLines("some.txt");
foreach (string config in configArray)
{
Match m = r.Match(config);
configuration.Add(m.Groups[1].Value, m.Groups[2].Value);
}
Please note to check for possible null values.
Note also that regex expression should be different if config values can contain for example spaces.
Just use:
var config = File.ReadAllLines(FileLocation)
And then parse it with the
String.Split()
Might use regex as well.

How to export csv to db in C#. It works fine when you have a plain text simple text. But in my case I need to parse headers as single row.
There are many options!
use some driver custom functions (depends on your database)
use a [schema.ini](
https://learn.microsoft.com/en-us/sql/odbc/microsoft/schema-ini-file-text-file-driver)
do it manually ...
You can do it manually with while iteration. Before using loop, you should read csv file from path with StreamReader.
For example:
using(var csvReader = new StreamReader(System.IO.File.OpenRead("your file path")))
{
while (!csvReader.EndOfStream)
{
var rows = csvReader.ReadLine();
var columns = rows.Split(';');
if(values.Length > 1)
{
// Your logic getting values to save db
}
}
}

Help write a regular expression to search for files and folders,
searches for a given mask. In the mask, you can use "*"
(any characters in any number), and the "?" (one symbol).
Here shows you how to use regex in C#.
You could always just loop the directory that you're looking in and check the file names instead of making a regex. (You'll need to use System.IO)
Perhaps something like this?
string [] fileEntries = Directory.GetFiles(targetDirectory);
Regex regex = new Regex("target file name");
Match match = regex.Match(string.Join(" ", fileEntries););
if (match.Success)
{
Console.WriteLine(match.Value);
}

I need to read accounts.txt and add/change number after password
Here is accounts.txt
user|password
user1|password1
After starting
user|password|1
user1|password1|1
After closing
user|password|0
user1|password1|0
Sorry for my english
Add this reference first System.IO Then:
For reading:
string[] accounts= File.ReadAllLines("accounts.txt");
//each item of array will be your account
For modifying :
accounts[0] += "|1";//this adds "|1" near password
accounts[0].Replace("|1","|0"); this will change the "|0" text to "|1"
And For writing:
File.WriteAllLines("accounts.txt",accounts);
Look at System.IO.File class, as well as general System.IO.Stream and System.IO.StreamReader classes.
There are a bunch of examples on the internet on how to read and write text files in .NET: http://msdn.microsoft.com/en-us/library/db5x7c0d(v=vs.110).aspx
Something like that :
string[] lines = File.ReadAllLines(#"C:\filepath.txt");
List<string> newlines = new List<string>();
foreach(string line in lines)
{
string[] temp = line.Split('|');
newlines.Add(temp[0] + "|" + temp[1] + "|" + "1");
}
File.WriteAllLines(#"C:\filepath.txt", newlines.ToArray())

I saved few directory locations to a Dictionary<string, string>,
e.g.
C:\\WINDOWS\\system32\\abc\\123
But the value that gets stored in the dictionary is C:\WINDOWS\system32\abc\123
So when I later compare a value against one in the dictionary it does a comparison like this:
C:\WINDOWS\system32\abc\123
to this
C:\\WINDOWS\\system32\\abc\\123
How can I retain backslashes when storing values in a Dictionary?
Try this:
Dict.Add(key, #"C:\\WINDOWS\\system32\\abc\\123");
\ is an escape character. Adding # makes your string a string literal instead.
EDIT I've reproduced your issue and this fix will solve it.
Use the # symbol in front of the strings when saving. That should solve it.

I have a lot of txt files in Resources folder. One of them is corner.txt. I can access this file via this code snippet:
Properties.Resources.corner
I keep file names in string variables. For example:
string fileName = "corner.txt";
I want to access this file via:
Properties.Resources.fileName
Is this possible? How can I access?
I solved the problem this code snippet:
string st = Properties.Resources.ResourceManager.GetString(tableName);
So, I don't use the filename, I use the txt file's string. This is useful for me.
Thanks a lot.
You can use Reflection like that:
var type = typeof(Properties.Resources);
var property = type.GetProperty(fileName, BindingFlags.Static| BindingFlags.NonPublic|BindingFlags.Public);
var value = property.GetValue(null, null);
or use the ResourceManager like that:
value = Properties.Resources.ResourceManager.GetObject(fileName, Properties.Resources.Culture);
