Question

I came across this code :

int myInt = 0;
textBox1.Text = myInt.GetType().Name;

According to the .NET documentation, GetType() is a method, not a class.

My question is that how am I able to use the dot with a method, like this GetType().Name?

Answer 1

A method can return a class instance, here it´s an instance of the class Type. On this object you can access properties, other methods, etc.

Your code could be written as this:

int myInt = 0;
Type t = myInt.GetType();
textBox1.Text = t.Name;

Maybe it´s easier to understand that way.

Edit:
A method call like GetType() executes the method, and everything you do after the . applies to the return value of the method, in this case an object of type Type.
