asp.net如何发起post请求？

<form action="post">
或者
$.post

public static string Post(string Url, string Data)
        {
            string result = "";
            WebClient myClient = new WebClient();
            myClient.Headers.Add("U-ApiKey", "XOO");
            myClient.Encoding = System.Text.Encoding.UTF8;
            try
            {
                result = myClient.UploadString(Url, Data);
            }
            catch (Exception ex)
            {
                result = ex.Message;
            }
            return result;
        }
发送post并且获取返回值

Dim data As Byte()
data = System.Text.Encoding.UTF8.GetBytes("token=03b92716-d6f9-490f-86c1-c4c017832083&ip=202.101.172.46“)Dim myReq As System.Net.HttpWebRequest = System.Net.WebRequest.Create(”http://www.s2m.cc/rest/ip/getAddress/“)
myReq.Method = "POST"
myReq.ContentType = "application/x-www-form-urlencoded;charset=UTF-8"
myReq.ContentLength = data.LengthDim myStream As System.IO.Stream = myReq.GetRequestStream
myStream.Write(data, 0, data.Length)
myStream.Close()Dim myResponse As System.Net.HttpWebResponse = myReq.GetResponse
myStream = myResponse.GetResponseStream
Dim myStreamReader As New System.IO.StreamReader(myStream)
Response.Write(myStreamReader.ReadToEnd)myStreamReader.Close()
myStreamReader = Nothing
myStream.Close()
myStream=Nothing
myReq = Nothing

        ///<summary>
        ///【POST】获取网站的html
        ///</summary>
        ///<param name="URL">url地址</param>
        ///<param name="strPostdata">发送的数据,格式：id=1&idd=2&type=3</param>
        ///<param name="Enco">编码格式，例如 utf-8【默认】,gb2312</param>
        ///<returns></returns>
        public static string PostWebHtml(string URL, string strPostdata, string Enco = "UTF-8")
        {
            strPostdata = strPostdata.FCoding(1)
                .Replace("%3d", "=")
                .Replace("%26", "&")
                .Replace("%3f", "?")
                .Replace("%3a", ":")
                .Replace("%2f", "/");            Encoding encoding = Encoding.Default;
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
            request.Method = "post";
            request.Accept = "text/html, application/xhtml+xml, */*";
            request.ContentType = "application/x-www-form-urlencoded";
            byte[] buffer = encoding.GetBytes(strPostdata);
            request.ContentLength = buffer.Length;
            request.GetRequestStream().Write(buffer, 0, buffer.Length);
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            using (StreamReader reader = new StreamReader(response.GetResponseStream(), System.Text.Encoding.GetEncoding(Enco)))
            {
                return reader.ReadToEnd();
            }
        }

strPostdata = strPostdata.FCoding(1)
                .Replace("%3d", "=")
                .Replace("%26", "&")
                .Replace("%3f", "?")
                .Replace("%3a", ":")
                .Replace("%2f", "/");
这块可以去掉。我是为了防止中文乱码才加上的

后台代码用 HttpRequest
js代码用jquery $.ajax({ type:post})

WebClient .UploadString

前台使用ajax，后台 httprequest
