C# work with functions

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

You Method is of type "void" so there is no return value

If you want to return a number of type int you have to declare your method to be of type int instead of void

Maybe you should grab a book and read the very raw principles of c# first before posting here

Your function (typically referred to as a 'method' in C#) is defined as returning void. Change it to:

public int number_p(int number)

At first glance, it looks like the problem may be that your function is declared to return void (i.e. nothing). Try changing it to return int.

public int number_p(int number)
{
    int one = 1;
    number = number + one;
    return number;
}
