What's up with this, anyway? I do a simple multiplication:

Int64 x = 11111111111;
Int64 y = 11111111111;
Int64 z = x * y;

And at the end of the multiplication, z shows a value of:

-5670418394979206991

This has clearly overflowed, but no exception is raised. I'd like one to be raised, but...

Note that this is on Windows Phone 7, but I don't think this has any bearing on the issue. Or does it?

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
