method in method

Question

Hi
this code works, but i have three questions:
1) why is static before  void hello2() (wrong version of c#?)
2) Because method hello2() is non-static, how come it is called without instance?
3) what difference does it make between  void hello2()  and static   void hello2()  (asuming it's allowed)?
Thanks
using System;
class Oef1
{
static void hello()
{
string name = "Bob";
Console.WriteLine(name);
void hello2()
{
string vname = "Bill";
Console.WriteLine(vname);
}
hello2();
}
static void Main()
{ hello(); }
}

Hello Valerie
1) why is static before  void hello2()
This is normal static method. But, unlike a regular function, is not associated with an instance of the class.
2) Because method hello2() is non-static, how come it is called without instance?
hello2() is a local function. The local function allows you to declare a method inside the body of an already defined method. Or in other words, we can say that a local function is a private function of a function whose scope is limited to that function in which it is created. The type of local function is similar to the type of function in which it is defined. You can only call the local function from their container members.

3) what difference does it make between  void hello2()   and  static   void hello2().
In C# 8.0, you are allowed to use a static modifier with the local function. This ensures that the static local function does not reference any variable from the enclosing or surrounding scope. If a static local function tries to access the variable from the enclosed scope, then the compiler will throw an error.
