How do I extend a class with c# extension methods?

Question

Can extension methods be applied to the class?

For example, extend DateTime to include a Tomorrow() method that could be invoked like:

DateTime.Tomor         


        

Answer 1

I would do the same as Kumu

namespace ExtensionMethods
{
    public static class MyExtensionMethods
    {
        public static DateTime Tomorrow(this DateTime date)
        {
           return date.AddDays(1);
        }    
    }
}

but call it like this new DateTime().Tomorrow();

Think it makes more seens than DateTime.Now.Tomorrow();
