You could do it this way:

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        // This is the square method
        // C# has no funtions
        // Watch out for overflow here
        int Square(int x)
        {
            return x * x;
        }

        // This is the Click handler of a button I put on the form
        private void Compute_Click(object sender, EventArgs e)
        {
            int X;
            // Parse the text of the textbox
            // You should test here that it contains only digits
            X = int.Parse(inputTextbox.Text);
            // Put the output of the calculation back in the sam place
            inputTextbox.Text = Square(X).ToString();
        }

    }
