HttpClient.TrySendRequestAsync Method

  • Reference

Definition

Namespace:
Windows.Web.Http

Overloads

TrySendRequestAsync(HttpRequestMessage)

Sends an HTTP request to the specified Uri as an asynchronous operation. For programming guidance for the HttpClient class, and code examples, see the HttpClient conceptual topic.
TrySendRequestAsync(HttpRequestMessage, HttpCompletionOption)

Sends an HTTP request with a completion option to the specified Uri as an asynchronous operation. For programming guidance for the HttpClient class, and code examples, see the HttpClient conceptual topic.

TrySendRequestAsync(HttpRequestMessage)

Edit

Sends an HTTP request to the specified Uri as an asynchronous operation. For programming guidance for the HttpClient class, and code examples, see the HttpClient conceptual topic.

public:
 virtual IAsyncOperationWithProgress<HttpRequestResult ^, HttpProgress> ^ TrySendRequestAsync(HttpRequestMessage ^ request) = TrySendRequestAsync;
/// [Windows.Foundation.Metadata.Overload("TrySendRequestAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperationWithProgress<HttpRequestResult, HttpProgress> TrySendRequestAsync(HttpRequestMessage const& request);
[Windows.Foundation.Metadata.Overload("TrySendRequestAsync")]
[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperationWithProgress<HttpRequestResult,HttpProgress> TrySendRequestAsync(HttpRequestMessage request);
function trySendRequestAsync(request)
Public Function TrySendRequestAsync (request As HttpRequestMessage) As IAsyncOperationWithProgress(Of HttpRequestResult, HttpProgress)

Parameters

request
HttpRequestMessage

The HTTP request message to send.

Returns

IAsyncOperationWithProgress<HttpRequestResult,HttpProgress>

The object representing the asynchronous operation.

Attributes
OverloadAttribute RemoteAsyncAttribute

Windows requirements

Device family
Windows 10, version 1903 (introduced in 10.0.18362.0)
API contract
Windows.Foundation.UniversalApiContract (introduced in v8.0)

Remarks

This operation will not throw an exception on network errors. Instead you should examine the HttpRequestResult to learn about the original HTTP request, the resulting HTTP response (if any) and error (if any). This operation will throw when the operation is canceled.

This operation will not block. The returned IAsyncOperationWithProgress (of HttpRequestResult and HttpProgress) completes after the whole response (including content) is read.

function trySendRequestAsync(request, completionOption)
Public Function TrySendRequestAsync (request As HttpRequestMessage, completionOption As HttpCompletionOption) As IAsyncOperationWithProgress(Of HttpRequestResult, HttpProgress)

Parameters

request
HttpRequestMessage

The HTTP request message to send.

completionOption
HttpCompletionOption

A value that indicates whether the HttpClient operation is considered completed when all of the response is read, or when just the headers are read.

Returns

IAsyncOperationWithProgress<HttpRequestResult,HttpProgress>

The object representing the asynchronous operation.

OverloadAttribute RemoteAsyncAttribute

Windows requirements

Windows 10, version 1903 (introduced in 10.0.18362.0)
API contract

Remarks

This operation will not throw an exception on network errors. Instead you should examine the HttpRequestResult to learn about the original HTTP request, the resulting HTTP response (if any) and error (if any). This operation will throw when the operation is canceled.

This operation will not block. The returned IAsyncOperationWithProgress (of HttpRequestResult and HttpProgress) completes based on the completionOption parameter after part or all of the response (including content) is read.
