Using Anonymous Method in C#




Implementing an Anonymous Method:

-Open windows form application

public Form1()
        {
            InitializeComponent();

            Button btnHello = new Button();
            btnHello.Text = "Hello";

            btnHello.Click +=
                delegate
                {
                    MessageBox.Show("Hello");
                };

            Controls.Add(btnHello);
        }



Using Parameters with Anonymous Methods

Button btnHello = new Button();
            //Button btnGoodBye = new Button();
            btnHello.Text = "Hello";

            btnHello.Click +=
                delegate(object sender, EventArgs e)
                {
                    string message = (sender as Button).Text;
                    MessageBox.Show(message);
                };

            Controls.Add(btnHello);


Why should we use Anonymous method?

We can reduce the code by preventing delegate instantiation and registering it with methods. It increases the
readability and maintainability of our code by keeping the caller of the method and the method itself as close to one another as possible
