Do you think that C# will support something like ??= operator?

Instead of this:

if (list == null)
  list = new List<int>();

It might be possible to write:

list ??= new List<int>();

Now, I could use (but it seems to me not well readable):

list = list ?? new List<int>();

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
