Both Method1() and GiveAction() are instance method (as apposed to static methods) and therefor there's no problem at all accessing Method1() from GiveAction(). Now, let's take a look at the code and add some comments to explain what's going on:

class Program
{
    // An instance field.
    int i = 4; 

    // The only static method in the class, also, the traditional starting point of c# applications.
    static void Main(string[] args)
    {
        // Set p as a new instance of the Program class.
        Program p = new Program(); 

        // Action y1 is initialized with the result of p.GiveAction() which is p.Method1().
        Action y1 = p.GiveAction(); 

        // This execute p.Method1(), so does the next row.
        y1();
        y1();
        Console.WriteLine();
    }

    // An instance method returning an Action.
    private  Action GiveAction()
    {
        return new Action(Method1);
    }

    // An instance method.
    public  void Method1()
    {
        this.i++;
    }
}
