c#如何读INI文件中的设置信息-.NET教程,C#语言

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;

}
