## App.xaml ##

> 程序启动文件

### App.xaml ###

引入资源程序集

```css
```

### App.xaml.cs ###

ValidatInstance 设置程序为单例 

定义整个应用程序需要用到的变量

```css
	namespace CFileWall
	{
	    ///
	    /// App.xaml 的交互逻辑
	    ///
	    public partial class App : Application
	    {
	        Mutex mutex;
	        public static FileInfo[] Files { get; set; }
	        public static CFileWall.Model.FileModel[] FileModels { get; set; }
	
	        protected override void OnStartup(StartupEventArgs e)
	        {
	            ValidatInstance();
	            Environment.CurrentDirectory = AppDomain.CurrentDomain.BaseDirectory;
	
	            base.OnStartup(e);
	        }
	
	        void ValidatInstance()
	        {
	            bool creatednew = false;
	            mutex = new Mutex(false, "CFileWall", out creatednew);
	            if (!creatednew)
	            {

	                App.Current.Shutdown();
	                return;
