OpenReadCompletedEventArgs.Result Property

Gets a readable stream that contains data downloaded by a DownloadDataAsync method.

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

'Declaration
Public ReadOnly Property Result As Stream

Property Value

Type: System.IO.Stream
A Stream that contains the downloaded data.

You should check the Error and Cancelled properties before using the data that is 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 OpenReadCallback2(ByVal sender As Object, ByVal e As OpenReadCompletedEventArgs)

            Dim reply As Stream = Nothing 
            Dim s As StreamReader = Nothing 

            Try

                reply = CType(e.Result, Stream)
                s = New StreamReader(reply)
                Console.WriteLine(s.ReadToEnd())
            Finally 

                If Not s Is Nothing Then

                    s.Close()
                End If 

                If Not reply Is Nothing Then

                    reply.Close()
                End If 
            End Try 
        End Sub
