範例

下列程式代碼範例會設定 Accept 屬性。

HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( myUri ) );
// Set the 'Accept' property to accept an image of any type.
myHttpWebRequest->Accept = "image/*";
// The response object of 'HttpWebRequest' is assigned to a 'HttpWebResponse' variable.
HttpWebResponse^ myHttpWebResponse = (HttpWebResponse^)( myHttpWebRequest->GetResponse() );

// Create a 'HttpWebRequest' object.
HttpWebRequest myHttpWebRequest=(HttpWebRequest)WebRequest.Create(myUri);
// Set the 'Accept' property to accept an image of any type.
myHttpWebRequest.Accept="image/*";
// The response object of 'HttpWebRequest' is assigned to a 'HttpWebResponse' variable.
HttpWebResponse myHttpWebResponse=(HttpWebResponse)myHttpWebRequest.GetResponse();

' Create a 'HttpWebRequest' object.
Dim myHttpWebRequest As HttpWebRequest = WebRequest.Create(myUri)
' Set the 'Accept' property to accept an image of any type.
myHttpWebRequest.Accept = "image/*"
' The response object of 'HttpWebRequest' is assigned to a 'HttpWebResponse' variable.
Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)

備註

謹慎

WebRequest、HttpWebRequest、ServicePoint和 WebClient 已經過時，您不應該將它們用於新的開發。 請改用 HttpClient。

若要清除 Accept HTTP 標頭，請將 Accept 屬性設定為 null。

注意

此屬性的值會儲存在 WebHeaderCollection中。 如果已設定 WebHeaderCollection，屬性值就會遺失。
