params

C# spec. allows you to call a function

void foo(params int[] x)

with zero parameters. However, I didn't find in C# Lang. Spec. a word on further behaviour -- will foo get empty array or null reference? I checked also MSDN -- nothing.

Where the behaviour is defined?

NOTE: I am not asking how VS behaves, I am asking about design of the language.

Dynamic Type to do away with Reflection

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
