Unable to cast COM object of type 'System.__ComOb ject' to class type 'System.String

[Bigi]

Hi,

Please help, this has been driving me nuts for nearly 2 days now.

This vb6 code works:

Public oEng As New ebizEngine
Public oMsg As ebizMessage

Function EbizGetFromQueu e() As String
Set oMsg = oEng.RecvMessag e
If oMsg Is Nothing Then
' the end
EbizGetFromQueu e = "*END"
Else
EbizGetFromQueu e = oMsg.Body
End If

In c# I have this:

private eBiz2000.ebizEn gineClass ebizEngine = new eBiz2000.ebizEn gineClass();

public string getFromQueue()
{
eBiz2000.ebizMe ssage ebizMessage;
ebizMessage = ebizEngine.Recv Message();
if (ebizMessage == null) // not sure about this??
{
return "*END";
}

return (string)ebizMes sage.Body;
}

When this runs I get the error Unable to cast COM object of type 'System.__ComOb ject' to class type 'System.String' . Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface.
I've tried numerous things with no success, any help is greatly appreciated.

ebizMessage.Bod y is not a string type.

ebizMessage.Bod y is not a string type.

It is an object, how can I get to the string it contains? How does the vb work but not the c#?
