HttpContentMultipartExtensions.ReadAsMultipartAsync<T> Method (, T, Int32)

Reads all body parts within a MIME multipart message and produces a set of HttpContent instances as a result using the streamProvider instance to determine where the contents of each body part is written and bufferSize as read buffer size.

Namespace:  System.Net.Http
Assembly:  System.Net.Http.Formatting (in System.Net.Http.Formatting.dll)

Type Parameters

  • T
    The type of the MIME multipart.


  • content
    Type: HttpContent

    An existing HttpContent instance to use for the object's content.

  • streamProvider
    Type: T

    A stream provider providing output streams for where to write body parts as they are parsed.

  • bufferSize
    Type: System.Int32

    Size of the buffer used to read the contents.

Return Value

Type: System.Threading.Tasks.Task<T>
A Task<TResult> representing the tasks of getting the collection of HttpContent instances where each instance represents a body part.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type HttpContent. When you use instance method syntax to call this method, omit the first parameter. For more information, see or
