OpenWriteCompletedEventArgs.Result Property

Gets a writable stream that is used to send data to a server.

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

'Declaration
Public ReadOnly Property Result As Stream

Property Value

Type: System.IO.Stream
A Stream where you can write data to be uploaded.

You should check the Error and Cancelled properties before using the stream returned by this property. If the Error property's value is an Exception object or the Cancelled property's value is true, the asynchronous operation did not complete correctly and the Result property's value will not be valid.

The following code example uses the stream returned by this property.

Private Shared Sub OpenWriteCallback2(ByVal sender As Object, ByVal e As OpenWriteCompletedEventArgs)

            Dim body As Stream = Nothing 
            Dim s As StreamWriter = Nothing 

            Try

                body = CType(e.Result, Stream)
                s = New StreamWriter(body)
                s.AutoFlush = True
                s.Write("This is content data to be sent to the server.")
            Finally 

                If Not s Is Nothing Then

                    s.Close()
                End If 

                If Not body Is Nothing Then

                    body.Close()
                End If 
            End Try 
        End Sub
