Private Access Specifiers (C#)


The private access specifiers restrict the member variable or function to be called outside from the parent class. A private function or variable cannot be called outside from the same class. It hides its member variable and method from other class and methods. However, you can store or retrieve value from private access modifiers using get set property. You will learn more about get set property in lateral chapter.


Example:

using System;

namespace Private_Access_Specifiers
{
  class access
   {
     // String Variable declared as private
     private string name;
     public void print() // public method
      {
        Console.WriteLine("\nMy name is " + name);
      }
   }

  class Program
   {
     static void Main(string[] args)
      {
        access ac = new access();
        Console.Write("Enter your name:\t");
        // raise error because of its protection level
        ac.name = Console.ReadLine();
        ac.print();
        Console.ReadLine();
      }
   }
}



Output:


Error 1: Private_Access_Specifiers.access.name' is inaccessible due to its protection level



 
In the above example, you cannot call name variable outside the class because it is declared as private.

Write a program to enter a number from 1 to 7 and display the corresponding day of the week. Hint: 1 = Monday ..

using System; class sevenday { public static void Main() { int num1; Console.WriteLine("Enter Number From 1 - 7 to find the correponding day"); num1=Convert.ToInt32(Console.ReadLine()); switch(num1) { case 1: Console.WriteLine(" 1 is Monday"); break; case 2: Console.WriteLine("2 is tuesday"); break; case 3: Console.WriteLine("3 is wednesday"); break; case 4: Console.WriteLine("4 is Thrusday"); break; case 5: Console.WriteLine("5 is friday"); break; case 6: Console.WriteLine("6 is saturday"); break; case 7: Console.WriteLine("7 is sunday"); break; default: Console.WriteLine(" Your Number is Invalid Please Enter Correct Number"); break; } } }

C# Statements

There are various basic things in C# that you need to know. These are very small but too effective. These are called statements in C#. Without covering statements in C#, you can’t be a good programmer. In C# programming, there is various statements as block, empty, goto-label, break, continue, return, throw, checked, unchecked, lock, using etc. These are small but give powerful control you to write your program. List of Contents C# Statements Chapter 1: Block Chapter 2: Empty Chapter 3: Goto-label Chapter 4: Break Chapter 5: Continue Chapter 6: Return Chapter 7: Throw Chapter 8: Checked Chapter 9: Unchecked Chapter 10: Lock Chapter 11: Using Chapter 12: Enumeration Chapter 13: Structure Chapter 14: Examples

C# Enumeration

Enumeration provides efficient way to assign multiple constant integral values to a single variable. Enumeration improves code clarity and makes program easier to maintain. Enumeration in C# also provides more security by better error-checking technology and compiler warnings. An enumeration can be defined using enum keyword. In enumeration, you can define special set of value that can be assigned with enumeration. For Example, you are creating an attendance log application in which a variable can contains value only Monday to Friday. The other value will not be applicable with variables. In order to fulfill this requirement you need to use enumeration that will hold only assigned values and will returns numeric position of values starting with zero. Programming Example of Enumeration (C#) using System; namespace Enumeration {    // creating enumeration for storing day.    public enum attandance    {       ...
