//類的構(gòu)造函數(shù)，傳遞ini文件名

// todo: add constructor logic here

}
//寫ini文件

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;
}
