c# - 在不实现 ICommand 的情况下创建 RelayCommand

Question

我的问题是如何创建一个行为与 RelayCommand 相同但不为我的 MVVM 应用程序实现 ICommand 的类？任何建议都非常感谢。

我的 RelayCommand [实现 ICommand] 如下：

 public class RelayCommand:ICommand
    {
        private readonly Action<object> m_Execute;
        private readonly Predicate<object> m_CanExecute;

        public RelayCommand(Action<object> exec) : this(exec, null) { }
        public RelayCommand(Action<object> exec, Predicate<object> canExec)
        {
            if (exec == null)
                throw new ArgumentNullException("exec");

            m_Execute = exec;
            m_CanExecute = canExec;
        }

        #region ICommand Members

        public bool CanExecute(object parameter)
        {
            if (parameter == null)
                return true;
            else
                return m_CanExecute(parameter);
        }

        public event EventHandler CanExecuteChanged
        {
            add
            {
                if (m_CanExecute != null)
                    CommandManager.RequerySuggested += value;
            }
            remove
            {
                if (m_CanExecute != null)
                    CommandManager.RequerySuggested -= value;
            }
        }

        public void Execute(object parameter)
        {
            m_Execute(parameter);
        }

        #endregion
    }
