Cannot call a function from a static method

Ok, this may sound like a very novice question.. i'm actually surprised i'm asking it. I can't seem to remember how to call a function from inside static void Main()

namespace myNameSpace
{
    class Program
    {
         static void Main()
         {
              Run(); // I receive an error here.
              Console.ReadLine();
         }
         void Run()
         {
              Console.WriteLine("Hello World!");
         }
    }
}

error:

An object reference is required for the non-static field, method, or property 'myNameSpace.Program.Run()'

The other way is to encapsulate your Run() method inside a nested class and invoke it.

        static void Main(string[] args)
    {
        new NestedClass().Run();
    }

    class NestedClass
    {
        public void Run()
        { 
        }
    }

cause static function is not associate with an instance. while the none static function must have an instance.
So you have to create a new instance (each way you want) and then call the function.

Run() must also be static or you need to create a new instance of the object like new Program().Run();

You need to either make Run a static method or you need an object instance to call Run() of. So your alternatives are:

1.) Use an instance:

new Program().Run();

2.) Make Run() static:

static void Run()
{
   /..
}

Declare your Run() method as static too:

static void Run()
{
   Console.WriteLine("Hello World!");
}
