interop

I have a C# COM server which is consumed by a cpp client.

One of the C# methods returns a string.

In cpp the returned string is represented in Unicode (UTF-16), at least according to the memory view.

Is this always the case with COM strings?
Is there a way to use UTF-8 instead?
I saw some code where strings were passed between cpp and c# as byte arrays. Is there any benefit in this?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
