difference between static and non-static members

Declaring a member in a class as static is a member of a static member class, or static, or non-static, in general, a static member is a non-static member belonging to a class and is an instance object of a class. The following example code demonstrates how to declare a static and Non-static member

Program Listing 10-5

Using System;

Class Test

{

int x;

static int y;

void F ()

{

x = 1; Correct, equivalent to This.x = 1

y = 1; Correct, equivalent to Test.y = 1

}

static void G ()

{

x = 1; Error cannot access this.x

y = 1; Correct, equivalent to Test.y = 1

}

static void Main ()

{

Test T = new Test ();

T.x = 1; That's right

T.Y = 1; Errors cannot access static members in instances of a class

Test.x = 1; Error cannot access non-static members by class

Test.y = 1; Correct}}

A non-static member of a class belongs to an instance of a class. All instances of creating a class open an area in memory for Non-static members, and the class's static members belong to all instances of the class, regardless of how many replicas the class creates. A static member occupies only one area of memory.
