Declare and set properties all at once

I used to use this technique in ActionScript, and I really like to use it C#:

TextBox textBox = new TextBox() { Text = "Hello!", Enabled = false };

TextBox textBox = new TextBox { Text = "Hello!", Enabled = false }; // Thanks, kfarmer

Point point = new Point(size) { X = 5 };

The only constructor that the TextBox class has is parameterless, but you can declare it and set its properties as shown in the examples. As kfarmer noted in his comment below, the parentheses are optionalĀ in case of a parameterless constructor.
