Using Dispose method in C#

This piece of code will show you some memory management in classes.

When we give application to client, we don't know how will he use that whether he will call dispose or not?

It may be missing at client side so our application should be smart enough to free used resources, here is code that will give the idea to implement finalizer and dispose in same class to take care of resource cleaning.

using System;
namespace disposeConsole
{
    class ResourceManagement : IDisposable
    {
        public ResourceManagement()
        {}
        private bool IsDisposed = false;
        public void Free()
        {
            if (IsDisposed)
                throw new System.ObjectDisposedException("Object Name");
        }
        //Call Dispose to free resources explicitly
        public void Dispose()
        {
            //Pass true in dispose method to clean managed resources too and say GC to skip finalize in next line.
            Dispose(true);
            //If dispose is called already then say GC to skip finalize on this instance.
            GC.SuppressFinalize(this);
        }
        ~ResourceManagement()
        {
            //Pass false as param because no need to free managed resources when you call finalize it will be done
            //by GC itself as its work of finalize to manage managed resources.
            Dispose(false);
        }
        //Implement dispose to free resources
        protected virtual void Dispose(bool disposedStatus)
        {
            if (!IsDisposed)
            {
                IsDisposed = true;
                // Released unmanaged Resources
                if (disposedStatus)
                {
                    // Released managed Resources
                }
            }
        }
    }
}
