How To Access Private Variables of a Class In another class in C#

In this blog you will learn How To Access Private Variables of a Class In another class in C#.

We can access private variable of a class in a different class in so many ways. Here is some of them:

1. By using Public Method
   
   We can access a private variable in a different class by putting that variable with in a Public method and calling that method from another class by creating object of that class.
   
   Example:
   

   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Text;
   namespace ConsoleApplication1
   {
       class PrivateVariable
       {
           private int i = 10; //Declaring and initializing a private variable
           public void DisplayVariable()
           {
               Console.Write("The Value of Private Variable=" + i); //Accessing Private variable with in a public methode
           }
       }
       class DisplayPrivateVariable
       {
           static void Main()
           {
               PrivateVariable objPrivateVariable = new PrivateVariable();
               objPrivateVariable.DisplayVariable(); //Calling the public method
           }
       }
   }

2. By Using Inner class
   
   By using inner class also we can access a private variable of a class in another class. For better understanding have look at the example.
   
   Example:
   

   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Text;
   namespace ConsoleApplication1
   {
       class PrivateVariable2
       {
           class Outerclass
           {
               private int i = 10;
               private int j = 20;
               class Innerclass
               {
                   static void Main()
                   {
                       Outerclass objouter = new Outerclass();
                       int Result = objouter.i + objouter.j;
                       Console.Write("Sum=" + Result);
                       Console.ReadLine();
                   }
               }
           }
       }
   }

3. By Using Properties
   
   By using properties also we can do the same work as previous.
   
   Example:
   

   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Text;
   namespace ConsoleApplication1
   {
       class Employee
       {
           private int _EmpID = 1001;
           private string _EmpName;
           public int EmpID
           {
               get
               {
                   return _EmpID;
               }
           }
           public string EmpName
           {
               get
               {
                   return _EmpName;
               }
               set
               {
                   _EmpName = "Smith";
               }
           }
       }
       class AcessEmployee
       {
           static void Main()
           {
               Employee objEmployee = new Employee();
               Console.WriteLine("Employee ID: " + objEmployee.EmpID);
               Console.WriteLine("Employee old Name: " + objEmployee.EmpName);
               objEmployee.EmpName = "Dyne Smith";
               Console.WriteLine("Employee New Name: " + objEmployee.EmpName);
               Console.ReadLine();
           }
       }
   }
