INI Read/Write

[Paul Thomas]

I had posted this in the downloads section for anyone who wants to use it: http://leadwerks.com/werkspace/index.php?app=downloads&showfile=58

 

A C++ forum post reminded me of this program I made during C# college classes to read/write to INI files. I provided source and DLL. It most likely will need to be expanded as I only went as far as I needed it for. It simply uses InteropServices to use "WritePrivateProfileString" and "GetPrivateProfileString."

Here's another C# implementation I made for one of my previous projects:

 

EDIT: Interesting, wonder how you did the "remove keys". Manual parsing or Kernel32?

EDIT2: I'll just download the source and see for myself. The description seems quite amazing.

 

using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Text;

public class IniFile
{
public string Path { get; set; }

[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 IniFile(string path, bool forceLoad)
{
	if (!File.Exists(this.Path))
	{
		throw new FileNotFoundException();
	}

	this.Path = path;
}

public void Write(string section, string key, string value)
{
	WritePrivateProfileString(section, key, value, this.Path);
}

public string Read(string section, string key)
{
	StringBuilder sb = new StringBuilder(255);
	GetPrivateProfileString(section, key, "", sb, 255, this.Path);

	string result = sb.ToString();

	if (result == string.Empty)
	{
		throw new Exception("Cannot read field \"" + key + "\" at section \"" + section + "\".");
	}
	else
	{
		return result;
	}
}
}

Yeah, could just combine the two.

 

ini.Read("category", "key");

 

Looks better than my ini.Key("category", "key");

 

I think back when I was writing this I was going to do ini.Read("category","key") to directly read from a category and make ini.Key("key") to iterate through the ini.Categories() and ini.Keys("category") to find that one key, but obviously dumped that idea.

 

It was a learning experience back then, it could use polishing and expanding.
