Copy Constructor in C#

         Unlike some languages, C# does not provide a copy constructor. If you create a new object and want to copy the values from an existing object, you have to write the appropriate method yourself.

The following program describes copy constructor...

class sample     {         string nme;         int number;         public sample()         {                 }                 // Parameterised Constructor.............         public sample(string name, int no)         {             this.nme = name;             this.number = no;         }         // Copy Constructor -------------------------         public sample (sample object11)         {             nme=object11.nme;             number = object11.number;                         }         public void show()         {             Console.WriteLine("Name is " + nme);             Console.WriteLine("Number is " + number);         }     }                 class Program     {         static void Main(string[] args)         {             sample obj = new sample("radha",101);             sample obj1 = new sample(obj);             obj.show();             obj1.show();             Console.Read();         }     } Output: Name is radha Number is 101 Name is radha Number is 101
