Question

I have following event class. I have a question related to the Property method set {userAccount = value;} It will make a copy of the userAccount object (deep copy?) or it will make a copy of the userAccount object reference (shallow copy?) Do I need to make a method in UserAccountInfo class to do value copy?

class EvEndGetUserAccount
    {
        private UserAccountInfo userAccount;

        /// <summary>
        /// An event class for getting user account
        /// </summary>
        /// <param name="account"></param>
        public EvEndGetUserAccount(UserAccountInfo account)
        {
            userAccount = account;
        }

        /// <summary>
        /// Get/Set userAccount
        /// </summary>
        public UserAccountInfo UserAccount
        {
            get { return userAccount; }
            set { userAccount = value; }
        }

        /// <summary>
        /// returns the content of this EvEndGetUserAccount event.
        /// </summary>
        /// <returns>string represent of the EvEndGetUserAccount object</returns>
        public override string ToString()
        {           
            return userAccount.ToString();
        }
    }

It will make a shallow copy, in other words it will just copy the reference. If you want to make a deep copy (or clone), add the IClonable interface to your class. It will force you to add a new Clone method that implements the exact deep-copying logic
