This example, shows how a method can return object in C#.Net?

C# program for method returning object

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1 {
  class Sample {
    //private data member
    private int value;

    //method to set value
    public void setValue(int v) {
      value = v;
    }

    //method to print value
    public void printValue() {
      Console.WriteLine("Value : " + value);
    }

    //methdo that will return an object 
    public Sample AddOb(Sample S1) {
      //creating object 
      Sample S = new Sample();
      //adding value of passed object in current object
      //and adding sum in another object 
      S.value = value + S1.value;
      //returning object 
      return S;
    }
  }

  //main class containing main method
  class Program {
    //main method 
    static void Main() {
      //declaring objects 
      Sample S1 = new Sample();
      Sample S2 = new Sample();

      //setting values to the objects
      S1.setValue(10);
      S2.setValue(20);

      //adding value of both objects, result will be 
      //assigned in the third object
      Sample S3 = S1.AddOb(S2);

      //printing all values
      S1.printValue();
      S2.printValue();
      S3.printValue();
    }
  }
}

Output

Value : 10
Value : 20
Value : 30

Explanation

In above program, we are creating a user define class named Sample. It contains a data member value. We create method AddOb(), it returns sum of current object and passed object into this method. Here, AddOb() method is returning the object.
