Convert these delegate lines from C # to vb.net

Here I have some code from Fleck that actually works fine in C # (no errors) and this is the line in the class library:

public Action<List<byte>> ReceiveData = delegate { };

then i convert it to vb.net using http://www.developerfusion.com/tools/convert/csharp-to-vb/

and this resulted in:

Public ReceiveData As Action(Of List(Of Byte)) = Function() Do

End Function

      

        
        
        
      

    

but an error occurs:

Do -> Expected Expression

End function -> End function must precede the corresponding function

can anyone tell me what is the valid vb.net code for this? thank
