範例

下列程式代碼範例會下載並顯示伺服器所傳回 ResponseHeaders

// Obtain the WebHeaderCollection instance containing the header name/value pair from the response.
WebHeaderCollection^ myWebHeaderCollection = myWebClient->ResponseHeaders;
Console::WriteLine( "\nDisplaying the response headers\n" );

// Loop through the ResponseHeaders and display the header name/value pairs.
for ( int i = 0; i < myWebHeaderCollection->Count; i++ )
{
   Console::WriteLine( "\t{0} = {1}", myWebHeaderCollection->GetKey( i ),
      myWebHeaderCollection->Get( i ) );
}
// Obtain the WebHeaderCollection instance containing the header name/value pair from the response.
WebHeaderCollection myWebHeaderCollection = myWebClient.ResponseHeaders;
Console.WriteLine("\nDisplaying the response headers\n");
// Loop through the ResponseHeaders and display the header name/value pairs.
for (int i=0; i < myWebHeaderCollection.Count; i++)				
    Console.WriteLine ("\t" + myWebHeaderCollection.GetKey(i) + " = " + myWebHeaderCollection.Get(i));
' ResponseHeaders is a WebHeaderCollection instance that contains the headers sent back 
 ' in response to the WebClient request. 
Dim myWebHeaderCollection As WebHeaderCollection = myWebClient.ResponseHeaders
Console.WriteLine(ControlChars.Cr + "Displaying the response headers" + ControlChars.Cr)
' Loop through the ResponseHeaders.
Dim i As Integer
For i = 0 To myWebHeaderCollection.Count - 1
    ' Display the headers as name/value pairs.
    Console.WriteLine((ControlChars.Tab + myWebHeaderCollection.GetKey(i) + " " + ChrW(61) + " " + myWebHeaderCollection.Get(i)))
Next i 

備註

謹慎

WebRequestHttpWebRequestServicePointWebClient 已經過時,您不應該將它們用於新的開發。 請改用 HttpClient

ResponseHeaders 屬性包含 WebHeaderCollection 實例,其中包含回應 WebClient 接收的標頭資訊。
