Parameters

• type
  Type: System.Type

  The type of the object to write.

• value
  Type: System.Object

  The object value to write. It may be null.

• writeStream
  Type: System.IO.Stream

  The Stream to which to write.

• content
  Type: HttpContent

  The HttpContent if available. It may be null.

• transportContext
  Type: System.Net.TransportContext

  The TransportContext if available. It may be null.

Return Value

Type: System.Threading.Tasks.Task
A Task that will perform the write.

Exceptions

Exception	Condition
NotSupportedException	Derived types need to support writing.

Remarks

This implementation throws a NotSupportedException. Derived types should override this method if the formatter supports reading. An implementation of this method should NOT close writeStream upon completion. The stream will be closed independently when the HttpContent instance is disposed.
