Declaration of the C # method

A method is a member of a class that is used to perform calculations or other behaviors. Let's look at the declaration format of the method:

Method-header Method-body

The format of the method header Method-header:

Attributes Method-modifiers Return-type member-name (formal-parameter-list)

The parameters passed to the method are declared in the formal parameter table Formal-parameter-list of the method, which we will discuss in detail later.

In the declaration of a method, at least the method name, modifier, and parameter type should be included, and the return value and parameter names are not required.

Note: The method name Member-name should not have the same name as the other methods in the same class or the other member names in the class.

Modifiers

The modifier method-modifier of the method can be:

New

Public

Protected

Internal

Private

Static

Virtual

Sealed

Override

Abstract

extern

For methods that use the abstract and extern modifiers, the execution body of the method method-body only a simple semicolon. All other method bodies should contain the statements to be executed to invoke the method.

return value

The type of the return value of a method can be a valid data type for C #. C # Gets the return value in the execution part of the method, such as:

Program Listing 11-1:

Using System;
Class Test
{public
  int max (int x,int y) {
    if (x>y) return
       x;
    else return
       y;
  }
  public void Main () {
     Console.WriteLine ("The max of 6 ADN 8 is:{0}", Max (6,8));
  }

The output of the program is:

The max of 6 and 8 Is:8

If you do not follow any value after return, the method returns the value is void.
