I was looking through some code the other day and ran across something that looked remotely familiar. It was the null coalescing (??) operator. I had read about this operator, but never used it. It was introduced with the .NET 2.0 Framework.
The null coalescing operator basically checks to see if a value is null and if so returns an alternate value. Below is a simple example.

@Patryksharks321: You’re talking about the conditional operator (?:) which C# also has.
I abuse this operator in “singleton-like” properties…
e.g.
private object myObject = null;
public object MyObject
{
get { return myObject ?? ( myObject = new object ( ) ); }
}
