Disposable pattern using IDisposable in C#

public interface ISomeInterface : IDisposable
    {
        void SomeMethod();
    }

    public class MyClass : ISomeInterface
    {
        public void SomeMethod()
        {
        }

        public void Dispose()
        {
            this.Dispose(true);
        }

        ~MyClass()
        {
            this.Dispose(false);
        }

        protected virtual void Dispose(bool disposing)
        {
            if (disposing)
                GC.SuppressFinalize(this);
        }
    }

Code to execute:

MyClass myClass = new MyClass();

            try
            {
                myClass.SomeMethod();
            }
            finally
            {
                myClass.Dispose();
                myClass = null;
            }

Please note that, if the object is of IDisposable; it is better to use using {....} block in C#. It internally takes care of the garbage collection.
