c#
Hi, I'am new with C#. How works in C# functions?
My try:
        private void Form1_Load(object sender, EventArgs e)
    {
        MessageBox.Show(Convert.ToString(number_p(5)));            
    }
    public void number_p(int number)
    {
        int one = 1;
        number = number + one;
        return number;
    }
Error: return, why? Thanks
