Assuming you have created a Class in your system. Which is an appropriate way of notifying the class that the object is going out of scope?

46.

No notification mechanism is available in .NET. .NET does it’s own memory management and therefore is unable to tell us when an object has gone out of scope.

You would need to implement the IDisposable interface in the class and wrap the instance of the object with the “using” block.

You would need to implement the Dispose method and call it manually right before the object went out of scope.

Either 2 or 3 would work.

View Description

The following sample shows how a user-defined class can implement its own Dispose behavior. Note that your type must inherit from IDisposable.

using System;
class C : IDisposable
{
    public void UseLimitedResource()
    {
        Console.WriteLine("Using limited resource...");
    }
    void IDisposable.Dispose()
    {
        Console.WriteLine("Disposing limited resource.");
    }
}

class Program
{
    static void Main()
    {
        using (C c = new C())
        {
            c.UseLimitedResource();
        }
        Console.WriteLine("Now outside using statement.");
        Console.ReadLine();
    }
}
