记录一下，调试使用

protected void btnSend_Click(object sender, EventArgs e)

        {

            string url = "http://localhost:3547/waplocation.aspx";
            string mobileNo = this.txtMobileNo.Text;

            StringBuilder reqStr = new StringBuilder(100);
            reqStr.Append("reqtype=" + txtReqType.Text + "&mobile=" + mobileNo);
            //reqStr.Append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
            //reqStr.Append("<request>");
            //reqStr.Append("<head><reqtype>" +txtReqType.Text +"</reqtype></head>");
            //reqStr.Append("<body>");
            //reqStr.Append("<mobiles>");
            //reqStr.Append("<mobile>" + mobileNo +"</mobile>");
            //reqStr.Append("</mobiles>");
            //reqStr.Append("</body>");
            //reqStr.Append("</request>");

            string postData = reqStr.ToString();

            ASCIIEncoding encoding = new ASCIIEncoding();
            byte[] data = encoding.GetBytes(postData);
            HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url);

            myRequest.Method = "POST";
            myRequest.ContentType = "application/x-www-form-urlencoded";
            myRequest.ContentLength = data.Length;
            Stream newStream = myRequest.GetRequestStream();


            newStream.Write(data, 0, data.Length);
            newStream.Close();

            HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
            StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.Default);
            string content = reader.ReadToEnd();
            txtResult.Text = content;

        }

如果公司设置了代理，可以这样：

try
{

string postData = "";

ASCIIEncoding encoding = new ASCIIEncoding();
byte[] data = encoding.GetBytes(postData);
WebProxy wp = new WebProxy("proxy Address");
wp.Credentials = new System.Net.NetworkCredential("username", "password","domain");

HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url);
myRequest.Proxy = wp;

myRequest.Method = "POST";
myRequest.ContentType = "application/x-www-form-urlencoded";
myRequest.ContentLength = data.Length;
Stream newStream = myRequest.GetRequestStream();

newStream.Write(data, 0, data.Length);
newStream.Close();

HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.Default);
string content = reader.ReadToEnd();
return content;
}

catch(Exception ex){

return string.Empty;
}
