C#中操作INI檔案

（一）INIFile.cs

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

namespace CreateWebDir
{
 /// <summary>
 /// INIFile 的摘要說明。
 /// </summary>
 public class INIFile
 {
  public string path;

  public INIFile(string INIPath)
  {
   path = INIPath;
  }

  [DllImport("kernel32")]
  private static extern long WritePrivateProfileString(string section,
   string key,string val,string filePath);//調用相關的API函數

  [DllImport("kernel32")]

  private static extern int GetPrivateProfileString(string section,
   string key,string def, StringBuilder retVal,int size,string filePath);

  public void IniWriteValue(string Section,string Key,string Value)
  {
   WritePrivateProfileString(Section,Key,Value,this.path);
  }

  public string IniReadValue(string Section,string Key)
  {
   StringBuilder temp = new StringBuilder(255);

   int i = GetPrivateProfileString(Section,Key,"",temp, 255, this.path);

   return temp.ToString();

  }

 }
}

=======================================================

（二）使用樣本

   string iniFile = @"D:/Bug2000.ini";
   if (!File.Exists(iniFile))
   {
    using (FileStream fs = File.Create(iniFile))
    {
     fs.Close();
    }
   }

   INIFile myINI = new INIFile(iniFile);

   for(i=0;i<args.Length;i++)
   {
    myINI.IniWriteValue("WebDir","arg"+i.ToString(),args[i]);
   }
