Saving and Restoring Application Settings

Do you specifically want to use an ini file, or do you just want to store settings? If it's the latter then you can use the built-in settings feature:

Use a ini file

This is a delphi line:

SettingsFile := ChangeFileExt(Application.ExeName, '.ini');

can someone translate this to C#

Oke, now how to read and write to ini-file

Greetings,

Peter

I don't want to use third party components.

Assuming you are storing them as name/value pairs, you can load all of your settings into a Dictionary:

Dictionary<string, string> configSettings = new Dictionary<string, string>();

string[] lines = File.ReadAllLines("Your_Config_File");
foreach (string line in lines)
{
       string[] arr = line.Split(new char[] { '=' });
       configSettings.Add(arr[0], arr[1]);
}

Select allOpen in new window

Do you have an example in C#?

Oke, Can someone tell me how to declare this:

[DllImport("kernel32")]
private static extern long WritePrivateProfileString(string strSection, string strKeys,string myVal,string theFile);
[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string strSection, string strKeys, string myDef, StringBuilder theReturnedValue, int varSize, string theFile);

I have this but I get an error:

The type or namespace name 'DllImport' could not be found (are you missing a using directive or an assembly reference?)      

P.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;

using System.Text;
using System.Windows.Forms;

namespace iniFile
{
    public partial class Form1 : Form
    {

    public string path;

    [DllImport("kernel32")]
    private static extern long WritePrivateProfileString(string section,
      string key,string val,string filePath);

    [DllImport("kernel32")]
    private static extern int GetPrivateProfileString(string section,
      string key,string def, StringBuilder retVal,
      int size,string filePath);


        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            string settingsFile = string.Concat(System.IO.Path.GetFileNameWithoutExtension(Application.ExecutablePath), ".ini");
         //   LoadSettings();
        }


    }
}

for c#, check http://jachman.wordpress.com/2006/09/11/how-to-access-ini-files-in-c-net/

Yeh, I have allready found that too. Could you please look at my last post
with the declaration of the two methods which are necessary to access an INI File.

I quess nobody knows the answer to my problem.

This was the answer: using System.Runtime.InteropServices;
