Hi guys!
 
I need to manage VirtualBox from a C# Net 4.0 app using the COM API. The problem is that I get a marshaling exception when i try to get the output from a program that has been executed on the guest.
 
The code that generates the exception is:
System.Array output = GuestProcess.Read(0, 2000, 5000);
The only return type that compiles is System.Array, but that throws the exception at runtime.
 
The exception is a SafeArrayTypeMismatchException:
Specified array was not of the expected type.
at System.StubHelpers.MngdSafeArrayMarshaler.ConvertSpaceToManaged(IntPtr pMarshalState, Object& pManagedHome, IntPtr pNativeHome)
at VirtualBox.IGuestProcess.Read(UInt32 aHandle, UInt32 aToRead, UInt32 aTimeoutMS)
 
How can i get around this problem?
