c# - Method Within A Method

Question

I am creating a C# library with some reusable code and was trying to create a method inside a method. I have a method like this:

public static void Method1()
{
   // Code
}

What I would like to do is this:

public static void Method1()
{
   public static void Method2()
   {
   }
   public static void Method3()
   {
   }
}

Then I could choose either Method1.Method2 or Method1.Method3. Obviously the compiler isn't happy about this, any help is much appreciated. Thanks.

If by nested method, you mean a method that is only callable within that method (like in Delphi) you could use delegates.

public static void Method1()
{
   var method2 = new Action(() => { /* action body */ } );
   var method3 = new Action(() => { /* action body */ } );

   //call them like normal methods
   method2();
   method3();

   //if you want an argument
   var actionWithArgument = new Action<int>(i => { Console.WriteLine(i); });
   actionWithArgument(5);

   //if you want to return something
   var function = new Func<int, int>(i => { return i++; });
   int test = function(6);
}
