使用 HttpBaseProtocolFilter 作為非同步作業傳送 HTTP 要求。

public:
 virtual IAsyncOperationWithProgress<HttpResponseMessage ^, HttpProgress> ^ SendRequestAsync(HttpRequestMessage ^ request) = SendRequestAsync;
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperationWithProgress<HttpResponseMessage, HttpProgress> SendRequestAsync(HttpRequestMessage const& request);
[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperationWithProgress<HttpResponseMessage,HttpProgress> SendRequestAsync(HttpRequestMessage request);
function sendRequestAsync(request)
Public Function SendRequestAsync (request As HttpRequestMessage) As IAsyncOperationWithProgress(Of HttpResponseMessage, HttpProgress)

參數

HttpRequestMessage
