.net(C#)如何读INI文件中的配置信息(转载)

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

namespace Sx_Mdi
{

 /// <summary>
 /// Summary description for Class1.
 /// </summary>
 public class IniFile
 {
  //文件INI名称
  public string Path;

  ////声明读写INI文件的API函数
  [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);

  //类的构造函数，传递INI文件名
  public IniFile(string inipath)
  {
   //
   // TODO: Add constructor logic here
   //
   Path = inipath;
  }

  //写INI文件
  public void IniWriteValue(string Section,string Key,string Value)
  {
   WritePrivateProfileString(Section,Key,Value,this.Path);

  }

  //读取INI文件指定
  public string IniReadValue(string Section,string Key)
  {
   StringBuilder temp = new StringBuilder(255);
   int i = GetPrivateProfileString(Section,Key,"",temp,255,this.Path);
   return temp.ToString();

  }

 }
}

操作范例：

public static SqlConnection MyConnection()
{
 string sPath;
 string ServerName,userId,sPwd,DataName;

 sPath = GetPath();
 IniFile ini = new IniFile(sPath);
 ServerName = ini.IniReadValue ("Database","server");
 userId = ini.IniReadValue ("Database","uid");
 sPwd = ini.IniReadValue ("Database","pwd");
 DataName = ini.IniReadValue ("Database","database");
 string strSql = "server =" + ServerName+";uid ="+ userId +";pwd =;database ="+ DataName;
　　　 SqlConnection myConn=new SqlConnection(strSql);
　　　 return myConn;
}
