If you're familiar with other programming languages, you might have come across the concept of functions. Methods are very similar to functions however they are tied to a class. You don't need to know about classes at this level.

In C#, when we want to reuse a piece of code many times at relevant places then we use something called a method.

Consider a method like a labeled block of code which we can execute on demand whenever we want:

If you look at the above image, we used countToTen as a reference for the boxed code on the right. Every method has a name, and we can execute the code in that method using the following syntax methodName();. There are cases where the syntax will be a bit different but we will discuss the syntax in detail in later chapters. Over here, the main idea is that a piece of code was labeled as countToTen and we executed it multiple times by writing countToTen() instead of writing the while code.

In programming, it is a good practice to follow the DRY principle. DRY means Don't Repeat Yourself. Therefore, methods and loops are an excellent method of eliminating repetitive code.
