Windows窗体应用程序C＃中的HTTP发布

我需要在C＃中编写一个表单应用程序，通过HTTP POST将参数发送到url，然后获取响应。

我真的没有意识到从哪里开始，这有可能吗？

提前谢谢，加尔。

首先请看

1- HttpWebRequest类

2- HttpWebResponse类

3- WebClient类

在MSDN中

Answer 2

这不是在C＃中，但你应该能够解释它。

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。
