1.4. Console I/O

Namespaces also play an important role in the organization of the .NET Framework documentation. To find the documentation for the Console class, look in the System namespace. You'll see that WriteLine isn't the only output method in the Console class. The Write method is very similar in that it also displays output to the console. The difference is that WriteLine terminates its output with a carriage return.

There are 18 different definitions of the Write method and 19 different definitions for the WriteLine method, each one with different arguments. These multiple versions of the same method are known as overloads. The compiler can usually figure out which overload a program wants to use by the number and types of the arguments passed to the method.
