The class header defines a class’s fields, properties, and methods.

If you try to pass a property to a ref or an out parameter, an error occurs.

To make a property read-only, omit the set accessor for the property.

Objects that are instances of a class cannot be stored in an array.

In C#, you are not allowed to use an uninitialized class field.

To make a property read-only, you must omit the get accessor for the property.

A property is a class member that behaves like a public field.

Auto-properties cannot have a private set accessor.

If you call a method that has a reference parameter, you must also write the keyword ref before the argument.

The name of a class’s constructor is the same as the name of the class.
