式門遁甲

一般的QueryString就直接在網址加參數就好
但如果是用Post的話則要用下面方法

public Stream GetWebData(string Url, string PostData)
{
 byte[] myData = Encoding.Default.GetBytes(PostData);

 HttpWebRequest myRequest = (HttpWebRequest)HttpWebRequest.Create(Url);
 myRequest.Method = "POST";
 myRequest.Accept = "*/*";
 myRequest.ContentType = "application/x-www-form-urlencoded";
 myRequest.ContentLength = myData.Length;

 Stream myStream = myRequest.GetRequestStream();
 myStream.Write(myData, 0, myData.Length);
 myStream.Close();

 HttpWebResponse myResponse;
 try { myResponse = (HttpWebResponse)myRequest.GetResponse(); }
 catch (Exception) { return null; }

 ResponseStream = myResponse.GetResponseStream();

 return ResponseStream;
}

上面函式的第一個參數Url就傳網址
上面函式的第二個參數PostData
就傳像下面這樣
string myPost = "";
myPost += "?area="   + "東北亞";
myPost += "&city1="  + "東京";
myPost += "&city2="  + "秋葉原";
myPost += "&name="   + "welkingunther";
