HttpClient.TryGetAsync Method

  • Reference

Definition

Namespace:
Windows.Web.Http

Overloads

TryGetAsync(Uri)

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

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

TryGetAsync(Uri)

Edit

Sends a GET 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> ^ TryGetAsync(Uri ^ uri) = TryGetAsync;
/// [Windows.Foundation.Metadata.Overload("TryGetAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperationWithProgress<HttpRequestResult, HttpProgress> TryGetAsync(Uri const& uri);
[Windows.Foundation.Metadata.Overload("TryGetAsync")]
[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperationWithProgress<HttpRequestResult,HttpProgress> TryGetAsync(System.Uri uri);
function tryGetAsync(uri)
Public Function TryGetAsync (uri As Uri) As IAsyncOperationWithProgress(Of HttpRequestResult, HttpProgress)

Parameters

uri
Uri Uri

The Uri the request is sent to.

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 tryGetAsync(uri, completionOption)
Public Function TryGetAsync (uri As Uri, completionOption As HttpCompletionOption) As IAsyncOperationWithProgress(Of HttpRequestResult, HttpProgress)

Parameters

uri
Uri Uri

The Uri the request is sent to.

completionOption
HttpCompletionOption

An HTTP completion option value that indicates when the operation should be considered completed.

Returns

IAsyncOperationWithProgress<HttpRequestResult,HttpProgress>

The object representing the asynchronous operation.

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.
