C#中怎么将XML作为参数post到接口

 

String xml = "<data>中文</data>";
String postData = "data=" + Server.UrlEncode(xml); ;
string strUrl = "http://localhost:29833/WebSite1/xx.aspx";      
// 准备请求... 
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(strUrl); 
myRequest.Method = "POST";       
myRequest.ContentType="application/x-www-form-urlencoded";
myRequest.ContentLength = postData.Length;
Stream newStream=myRequest.GetRequestStream();      
byte[] data = Encoding.GetEncoding("GB2312").GetBytes(postData);
// 发送数据 
newStream.Write(data,0,data.Length);
HttpWebResponse res = myRequest.GetResponse() as HttpWebResponse;
StreamReader sr  = new StreamReader(res.GetResponseStream(), Encoding.UTF8);
String ret = sr.ReadToEnd();
newStream.Close();
Response.Write("你提交的是：" + Server.HtmlEncode( ret));


//==========
接口的接收
Response.ClearContent();
Response.Write(Request.Form["data"]);
Response.End();
