GetByteArrayAsync(String)
- Source:
- HttpClient.cs

Sends a GET request to the specified Uri and return the response body as a byte array in an asynchronous operation.
public:
System::Threading::Tasks::Task<cli::array <System::Byte> ^> ^ GetByteArrayAsync(System::String ^ requestUri);public System.Threading.Tasks.Task<byte[]> GetByteArrayAsync (string requestUri);public System.Threading.Tasks.Task<byte[]> GetByteArrayAsync (string? requestUri);member this.GetByteArrayAsync : string -> System.Threading.Tasks.Task<byte[]>Public Function GetByteArrayAsync (requestUri As String) As Task(Of Byte())Parameters
- requestUri
- String
The Uri the request is sent to.
Returns
The task object representing the asynchronous operation.
Exceptions
The requestUri must be an absolute URI or BaseAddress must be set.
The request failed due to an underlying issue such as network connectivity, DNS failure, server certificate validation or timeout.
.NET Core and .NET 5 and later only: The request failed due to timeout.
The provided request URI is not valid relative or absolute URI.
Remarks
This operation will not block. The returned Task<TResult> object will complete after the whole response body is read.
Note
In case of timeout, different exceptions are thrown on different .NET implementations.
- HttpRequestException is thrown on all applicable .NET Framework versions.
- TaskCanceledException without any inner exception is thrown on all applicable .NET Core versions.
- TaskCanceledException that nests a TimeoutException is thrown on .NET 5 and later versions.

- requestUri
- Uri
The Uri the request is sent to.
Returns
The task object representing the asynchronous operation.
Exceptions
The requestUri must be an absolute URI or BaseAddress must be set.
The request failed due to an underlying issue such as network connectivity, DNS failure, server certificate validation (or timeout for .NET Framework only).
.NET Core and .NET 5 and later only: The request failed due to timeout.
Remarks
