  public void Method() {
    Console.WriteLine("Sample1.Method() called");
  }
}

// Creating class "Sample2"
class Sample2 {
  public void Method() {
    Console.WriteLine("Sample2.Method() called");
  }

// The main class
class NewDemo {
  // Main() code/function
  static void Main() {
    // Creating the obejcts with the help 
    // of new keyword
    Sample1 S1 = new Sample1();
    Sample2 S2 = new Sample2();
    
    // Calling the member function
    S1.Method();
    S2.Method();
  }
}

Output

Sample1.Method() called
Sample2.Method() called
Press any key to continue . . .

Explanation

In the above program, we created three classes Sample1, Sample2, and NewDemo. Sample1 and Sample2 class contains a method Method(). The NewDemo class contains the Main() method. In the Main() method we created the object S1 and S2 of Sample1 and Sample2 class. Then print the method Method() of both classes.
