窗体最小化、最大化、关闭按钮的命令WindowBtnCommand：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Input;

namespace SunCreate.Common.Controls
{
    public class WindowBtnCommand : ICommand
    {
        public Action<int> DoAction { get; set; }

        public event EventHandler CanExecuteChanged
        {
            add { CommandManager.RequerySuggested += value; }
            remove { CommandManager.RequerySuggested -= value; }
        }

        public bool CanExecute(object parameter)
        {
            return true;
        }

        public void Execute(object parameter)
        {
            if (DoAction != null)
            {
                DoAction(Convert.ToInt32(parameter));
            }
        }
    }
}
