these operate on the created data type:
System.IO.StreamReader nn = new StreamReader();
nn.Read();
nn.Write();
Static members thus operate on an instance of a class.
Along with static member, it is possible to create static variables. These are often
used to keep track of the number of instances of a class. An example is shown in
Program 8.4 where a static member variable of numberProfile is created to count
the number of instances of the class. This is part of the class, and not part of any instance
of it.
Program 8.4:
using System;
namespace ConsoleApplication5
{
class Profile
{
static int numberProfile=0;
string code, name, telephone;

public string Name
{

get { return name; }
}
public string Telephone
{
set { telephone=value; }
get { return telephone; }

public void Display()
{
Console.WriteLine("Code: " + code + " Name: " + name +
" Telephone: " + telephone);
Console.ReadLine();
}
public static void HowMany()
{
Console.WriteLine("There are " + numberProfile + " profiles ");
Console.ReadLine();
