C# INI配置文件

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; 
}
