Partial class in C#.Net


When we want to split class we use partial keyword. The main advantage of partial class is that more than one programmer can work on same class at a time i.e. they can implement same class.

Example

 

private void btnAdd_Click(object sender, EventArgs e)

        {

//creating instance of class

            c c1 = new c();

//calling add() method of class

            MessageBox.Show(c1.add(2, 4).ToString());

        }

 

        private void btnSub_Click(object sender, EventArgs e)

        {

            c c1 = new c();

//calling sub() method of class

            MessageBox.Show(c1.sub(4, 3).ToString());

        }

   

//half of the class is defined here

    public partial class c

    {

        public int add(int a, int b)

        {

            return a+b;

        }

    }       

 //another half of class c

public int sub(int a, int b)

        {

            return a - b;

        }
