INI檔案格式及其作業碼

INI檔案格式如下：

[Database]

server=wlq

database=mydatabase

uid=sa

pwd=123456

說明：（有4個key)

Section為：Database

Key為：server database uid pwd

/***************代碼******************/

using System;

using System.IO;

using System.Runtime.InteropServices;

using System.Text;

namespace Sx_Mdi

{

/// <summary>

/// Summary description for Class1.

/// </summary>

public class IniFile

{

//檔案INI名稱

public string Path;

////聲明讀寫INI檔案的API函數

[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);

//類的建構函式，傳遞INI檔案名稱

public IniFile(string inipath)

{

//

// TODO: Add constructor logic here

//

Path = inipath;

}

//寫INI檔案

public void IniWriteValue(string Section,string Key,string Value)

{

WritePrivateProfileString(Section,Key,Value,this.Path);

}

//讀取INI檔案指定

public string IniReadValue(string Section,string Key)

{

StringBuilder temp = new StringBuilder(255);

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

return temp.ToString();

}

}

}

操作範例：

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;

}
