- · Internal: Access limited to the containing of the program only
- · Protected: Access limited to the containing class or types derived from the
- contained class

Example for public
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace demo_18
{
public class test
{
public int x;
public int y;
}
class Program
{
static void Main(string[] args)
{
int result;
test test1 = new test();
test1.x = 5;
test1.y = 10;
result = test1.x + test1.y;
Console.WriteLine(result);
}
}
}
-- In the above program, class 'test' is initialized with public access modifier, hence that class is accessed by another class i.e., program
So we would get the output as
Output:
15
... press any key to continue
Private :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace demo_18
{
private class test
{
public int x;
public int y;
}
class Program
{
static void Main(string[] args)
{
int result;
test test1 = new test();
test1.x = 5;
test1.y = 10;
result = test1.x + test1.y;
Console.WriteLine(result);
}
}
}
In above namespace, demo_18 class test is intizlised with private access modifier, where the accessibility of the test class is limited to the class test only... So above program with produce error..
" Error 1 Elements defined in a namespace cannot be explicitly declared as private, protected, or protected internal D:\Suresh Babu\demo_18\demo_18\Program.cs 8 24 demo_18"
