下载IPLocation.dll
在项目中添加引用,引用IPLocation.dll
添加引用:using IPLocation.IPLocation;
关键函数介绍:
IPLocate(Byval StrConn as string,Byval StrIp as string)
其中:StrConn 为数据库连接字符串,如:Server.MapPath("QQWry.Dat")
StrIP 为查询IP
返回值是字符串型,是IP的地址
示例:
将QQWry.Dat放在网站的根目录下
string conn, ipstr, addstr;
conn = Server.MapPath("QQWry.Dat");
ipstr = TextBox1.Text;
addstr = IPLocation.IPLocation.IPLocate(conn, ipstr);
Label1.Text = "IP:" + ipstr + "<br>地址:" + addstr;
conn = Server.MapPath("QQWry.Dat");
ipstr = TextBox1.Text;
addstr = IPLocation.IPLocation.IPLocate(conn, ipstr);
Label1.Text = "IP:" + ipstr + "<br>地址:" + addstr;
