直接新建个程序集或类，你也可以自己改下，可直接调用。
using System;
using System.Runtime.InteropServices;
using System.Text;using System.IO;
namespace Ytu_CallCenter
{/// <summary>
/// Summary des cription for Class1.
/// </summary>
public class IniFile
{
//INI文件的名称
public string Path;//在这里声明读写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)
{
Path = inipath;
}//写INI文件
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();}
}
}
操作范例：
public static SqlConnection INIConnection()
{
string sPath,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;
}
