怎么post数据到一个网页

写post参数和需要接受数据的页面地址：

ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "PM=" + PM;
postData += ("&BID=" + BID);
postData += ("&BTYPE=" + BTYPE);

byte[] data = encoding.GetBytes(postData);

// Prepare web request...
HttpWebRequest myRequest =
(HttpWebRequest)WebRequest.Create("http://live.com/baike/BkUpdate.html");

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

// Send the data.
newStream.Write(data, 0, data.Length);
newStream.Close();

// Get response
HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.Default);
string content = reader.ReadToEnd();
Response.Write(content);

页面二用于接收参数

if (Request.Form["PM"] == null || Request.Form["BID"] == null || Request.Form["BTYPE"] == null)
{
Response.Write("Error: Parameter Error!");
return;
}

string pm = (Request.Form["PM"] == null ? "" : Request.Form["PM"].Trim());
string bid = (Request.Form["BID"] == null ? "" : Request.Form["BID"].Trim());
string btype = (Request.Form["BTYPE"] == null ? "" : Request.Form["BTYPE"].Trim());

以上代码已测试并成功
