Int i; for( i = 0; i 10; i ) . This would loop until i is no longer less than ten, increasing i by one each time.

Methods - Learn C# - Free Interactive C# Tutorial

http://www.learncs.org/en/Methods

Methods in C# are portions of a larger program that perform specific tasks. They can be used to keep code clean by seperating it into seperate pieces. They can also be used in more than one place allowing you to reuse previous code. In C# methods can be in the main program or can be in libraries, which are external files, containing classes and subroutines which can be imported into a program. This allows them to be distributed easily and used by multiple programs. Methods in C# are defined like this:.
