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)); } } } }
