Windows窗体应用程序C＃的HTTP发布

Question

我需要用C＃编写一个表单应用程序，该应用程序通过HTTP POST将参数发送到url，并获取响应。

我真的不知道从哪里开始，这有可能吗？

预先感谢，加尔。

首先请看

1- HttpWebRequest类

2- HttpWebResponse类

3- WebClient类

在MSDN中

Answer 2

这不在C＃中，但是您应该可以对其进行解释。

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，请告诉我。
