怎么使用POST发送大量数据

[zhendehao]

请教下
asp.net怎么使用POST发送大量数据，接收端需要怎么接收？

[三省Ta叔]

private bool Send(string url, string sendData)
{
string ecode = sendData;
try
{
WebRequest req = WebRequest.Create(url);
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";

string strQuery = ecode;
string dataSend = strQuery;
req.ContentLength = dataSend.Length;

byte[] buff = Encoding.Default.GetBytes(dataSend);
Stream reqStream = req.GetRequestStream();
reqStream.Write(buff, 0, buff.Length);
reqStream.Close();
return true;

}
catch (Exception ex)
{
Response.Write(ex.Message);
return false;
}
}

jie 收 就 Request.Form.ToString();
