Add method to auto-generated class

Question

How can I add bool Equals(object obj) method to class that is created automatically (in my case by edmx model).

One solution that I mean is to inherit this class and use this new class, but I'm looking for something different.

Answer 1

The class is partial, so you can create a new partial class.

public partial class MyClass
{
  bool Equals(object obj)
  {
    // code here
  }
}

Answer 2

You can use Extension Methods

public static class ExM
{
    public static bool Equals(this MyClass obj1, MyClass obj2)
    {
        // code here
    }
}

It will add that method Equals in Intellisense of MyClass object so that when you call it like this

bool b = MyClassObject1.Equals(MyClassObject2);
