打開網址發送POST

Question

如何打開網頁瀏覽器並在.net 2內發送POST

類似於這個html函數。

<form action="http:www.url.com/get" method="post"> 
    <input name="tt_2a" > 
    <input type="submit" value="submit"> 

我想要的東西喜歡我上面提到的HTML函數，打開一個URL，張貼一些東西，並在打開的頁面中看到結果。我不需要web respose。謝謝

如果你想要做的POST幕後的（即沒有進行瀏覽器顯示窗口/控件），這些鏈接可以幫助：

您可以在您的winforms應用程序中使用WebClient以使用網頁。

要張貼這樣的的WebRequest：

 // Create a request using a URL that can receive a post. 
     WebRequest request = WebRequest.Create ("http://www.contoso.com/PostAccepter.aspx "); 
     // Set the Method property of the request to POST. 
     request.Method = "POST"; 
     // Create POST data and convert it to a byte array. 
     string postData = "This is a test that posts this string to a Web server."; 
     byte[] byteArray = Encoding.UTF8.GetBytes (postData); 
     // Set the ContentType property of the WebRequest. 
     request.ContentType = "application/x-www-form-urlencoded"; 
     // Set the ContentLength property of the WebRequest. 
     request.ContentLength = byteArray.Length; 
     // Get the request stream. 
     Stream dataStream = request.GetRequestStream(); 
     // Write the data to the request stream. 
     dataStream.Write (byteArray, 0, byteArray.Length); 
     // Close the Stream object. 
     dataStream.Close(); 
     // Get the response. 
     WebResponse response = request.GetResponse(); 
     // Display the status. 
     Console.WriteLine (((HttpWebResponse)response).StatusDescription); 
     // Get the stream containing content returned by the server. 
     dataStream = response.GetResponseStream(); 
     // Open the stream using a StreamReader for easy access. 
     StreamReader reader = new StreamReader (dataStream); 
     // Read the content. 
     string responseFromServer = reader.ReadToEnd(); 
     // Display the content. 
     Console.WriteLine (responseFromServer); 
     // Clean up the streams. 
     reader.Close(); 
     dataStream.Close(); 
     response.Close();
