C# Language Tutorial => Underlying references of named method...

Example

When assigning named methods to delegates, they will refer to the same underlying object if:

They are the same instance method, on the same instance of a class

They are the same static method on a class

public class Greeter
{
    public void WriteInstance()
    {
        Console.WriteLine("Instance");
    }

    public static void WriteStatic()
    {
        Console.WriteLine("Static");
    }
}

// ...

Greeter greeter1 = new Greeter();
Greeter greeter2 = new Greeter();

Action instance1 = greeter1.WriteInstance;
Action instance2 = greeter2.WriteInstance;
Action instance1Again = greeter1.WriteInstance;

Console.WriteLine(instance1.Equals(instance2)); // False
Console.WriteLine(instance1.Equals(instance1Again)); // True

Action @static = Greeter.WriteStatic;
Action staticAgain = Greeter.WriteStatic;

Console.WriteLine(@static.Equals(staticAgain)); // True
