C#实现请求服务器，类似于asp下的getHTTPPage(url)功能

using System.Net;
using System.Text;
using System.IO;

public static CookieContainer Cook = new CookieContainer();
public static string CreatRequestGetResponse(string URL, string PostData)
{
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(URL);
myRequest.CookieContainer = Cook;
myRequest.KeepAlive = true;
myRequest.Method = "POST";
string postdata = PostData;
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
byte[] postarr = encode.GetBytes(postdata);
myRequest.ContentType = "application/x-www-form-urlencoded";
myRequest.ContentLength = postarr.Length;
Stream outStream = myRequest.GetRequestStream();
outStream.Write(postarr, 0, postarr.Length);
outStream.Close();
WebResponse myResponse = myRequest.GetResponse();
StreamReader SReader = new StreamReader(myResponse.GetResponseStream(), System.Text.Encoding.GetEncoding("UTF-8"));
return SReader.ReadToEnd();
}
