public class inifile

//文件ini名称
public string path;
////声明读写ini文件的api函数
[dllimport("kernel32")]

[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;
}
