Passing MemoryStream ByRef Issue

[Jason Taylor]

Hello,

I have created a Web service with the following web method;

<WebMethod()> _
Public Function HelloWorld(ByVa l myMemoryStream As
System.IO.Memor yStream) As String
Return "Hello World"
End Function

I have also created a Web application with the following subroutine;

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load
Dim mySample As New localhost.Sampl e
Response.Write( mySample.HelloW orld(Response.O utputStream))
End Sub

Line 2 of the Page_Load sub generates the error; Value of type
'System.IO.Stre am' cannot be converted to
'Sample_Debug.l ocalhost.Memory Stream'.

What should I do to fix this?

Thanks,

Jason.

Well to the best of my knowledge you can not pass a memory stream. i
won't serialize on its own, so I think web serivces will have issues
with it, but you can convert the memory stream to a byte array with the
ToArray method pass that through the web service, and then put it back
into a memorystream (one of the constructor overloads accepts a byte
array). However i have to be honest I am not sure if trying to move
memory stream acros a web service is wise in the first place. But then
again I don't know what you are trying to accomplish
