Calling Custom Constructors with Initialization Syntax

The previous examples initialized Point types by implicitly calling the default constructor on the

type:

// Here, the default constructor is called implicitly.

Point finalPoint = new Point { X = 30, Y = 30 };

If you wish to be very clear about this, it is permissible to explicitly call the default constructor

as follows:

// Here, the default constructor is called explicitly.

Point finalPoint = new Point() { X = 30, Y = 30 };

Do be aware that when you are constructing a type using the new initialization syntax, you are

able to invoke any constructor defined by the class or structure. Our Point type currently defines a

two-argument constructor to set the (

x, y) position. Therefore, the following Point declaration

results in an X value of 100 and a Y value of 100, regardless of the fact that our constructor arguments

specified the values 10 and 16:
