Underlying references of named method delegates
suggest changeWhen 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
Found a mistake? Have a question or improvement idea?
Let me know.
