MultipartContent.CreateContentReadStreamAsync Method

Definition

Namespace:

System.Net.Http

Assembly:

System.Net.Http.dll

Overloads

CreateContentReadStreamAsync()	Serializes the HTTP content to a stream using the multipart/* encoding as an asynchronous operation.
CreateContentReadStreamAsync(CancellationToken)	Serializes the HTTP content to a stream using the multipart/* encoding as an asynchronous operation.

CreateContentReadStreamAsync()

Source:

MultipartContent.cs

Serializes the HTTP content to a stream using the multipart/* encoding as an asynchronous operation.

protected:
 override System::Threading::Tasks::Task<System::IO::Stream ^> ^ CreateContentReadStreamAsync();

protected override System.Threading.Tasks.Task<System.IO.Stream> CreateContentReadStreamAsync ();

override this.CreateContentReadStreamAsync : unit -> System.Threading.Tasks.Task<System.IO.Stream>

Protected Overrides Function CreateContentReadStreamAsync () As Task(Of Stream)

Returns

Task<Stream>

The task object representing the asynchronous operation.

Remarks

This method overrides HttpContent.CreateContentReadStreamAsync to use a custom stream that contains an array, with each HTTP content and its boundary encoded and serialized to a MemoryStream instance.

This operation will not block. The returned Task<TResult> object will complete after all of the content has been written to the memory stream.

Once the operation completes, the Task<TResult>.Result property on the returned task object contains the stream that represents the multipart/* encoded HTTP content. The returned stream can then be used to read the content using various stream APIs.

CreateContentReadStreamAsync(CancellationToken)

Source:

MultipartContent.cs

Serializes the HTTP content to a stream using the multipart/* encoding as an asynchronous operation.

protected:
 override System::Threading::Tasks::Task<System::IO::Stream ^> ^ CreateContentReadStreamAsync(System::Threading::CancellationToken cancellationToken);

protected override System.Threading.Tasks.Task<System.IO.Stream> CreateContentReadStreamAsync (System.Threading.CancellationToken cancellationToken);

override this.CreateContentReadStreamAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.IO.Stream>

Protected Overrides Function CreateContentReadStreamAsync (cancellationToken As CancellationToken) As Task(Of Stream)

Parameters

cancellationToken

CancellationToken

The cancellation token to cancel the operation.

Returns

Task<Stream>

The task object representing the asynchronous operation.

Exceptions

OperationCanceledException

The cancellation token was canceled. This exception is stored into the returned task.
