Windows窗體應用程序C＃的HTTP發布

Question

我需要用C＃編寫一個表單應用程序，該應用程序通過HTTP POST將參數發送到url，並獲取響應。

我真的不知道從哪里開始，這有可能嗎？

預先感謝，加爾。

首先請看

1- HttpWebRequest類

2- HttpWebResponse類

3- WebClient類

在MSDN中

Answer 2

這不在C＃中，但是您應該可以對其進行解釋。

var
  Bytes: Array of Byte;
  Request: HttpWebRequest;
  RequestStream: Stream;
  Response: HttpWebResponse;
  ResponseStream: StreamReader;
begin  
    Bytes := Encoding.UTF8.GetBytes(Data); //Where data is your data (XML in my case)
    Request := WebRequest.CreateDefault(Uri.Create(URL)) as HttpWebRequest;
    Request.Method := 'POST';
    Request.ContentLength := Length(Bytes);
    Request.ContentType := 'application/xml'; //Set accordingly

    RequestStream := Request.GetRequestStream;
    RequestStream.Write(Bytes, 0, Length(Bytes));
    RequestStream.Close;

    Response := Request.GetResponse as HttpWebResponse;
    ResponseStream := StreamReader.Create(Response.GetResponseStream, Encoding.ASCII);
    Result := ResponseStream.ReadToEnd;
    ResponseStream.Close;

如果您需要澄清，請告訴我。
