Optional & Named Parameters in C# 4.0 at 8:09 PM

I have to say this is one of my favorite features added to this new version.  I don’t know how many times I have gone into method overload madness because C# has never supported optional parameters.  VB.Net always has…why not C#?  Well, now it does!

public void AddUser(string firstName, string lastName, string status = "New User") {
  User = new User(firstName, lastName, status);
}

Now this method could be called in a few ways:

AddUser("Sean", "Jaeger", "Working right now");
AddUser("Sean", "Jaeger");
AddUser(lastName: "Jaeger", firstName: "Sean");

Pretty darn  cool!
