c#如何读INI文件中的设置信息

领测软件测试网 把下面的代码改动一下，就可以在你的程序中使用，当然
别忘记加上名字空间哦。
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;
}
