Define methods in C#

When you define a method, you are essentially declaring elements of its structure. In C#, the syntax for defining methods is as follows:

(Parameter List){ Method Body}

Here are the elements of the method:

Access Specifier: An access modifier that determines the visibility of a variable or method to another class.

Return type: A method can return a value. The return type is the data type of the value returned by the method. If the method does not return any value, the return type is void.

Method name: A unique identifier that is case-sensitive. It cannot be the same as other identifiers declared in the class.

Parameter list: A list of parameters, enclosed in parentheses, that are data used to pass and receive methods. Parameter lists refer to the type, order, and number of parameters for a method. Parameters are optional, that is, a method may not contain parameters.

Method body: The body of the method, containing the instruction set needed to complete the task.

examples

The following code snippet shows a function FindMax that takes two integer values and returns the larger of the two. It has the public access modifier, so it can be accessed from outside the class using instances of the class.

examples

class NumberManipulator

{

public int FindMax(int num1, int num2)

{

/* Local variable declaration */

int result;

if (num1 > num2)

result = num1;

else

result = num2;

return result;

}

...

}
