这篇主要解决宝妈不用到配置文件去改视频存放路径的问题，而是改成界面的方式。而我是打算使用Json格式，保存配置的数据。那么需要做的是主界面需要一个入口，弹入设置界面。
主界面自定义
由于需要在标题栏是加按钮，只能自定义了，不过WPF似乎有瑕疵，自定义了以后时不时的出现白边。

关键点
自定义后，顶部我们习惯了可拖拽，那还需要加上这句，但加了之后，会导致 关闭、最大化、设置等按钮，点不到，所以需要在这些控件属性，加是穿透 WindowChrome.IsHitTestVisibleInChrome="True"

WPF文件夹选择窗
//播放器选择
System.Windows.Forms.OpenFileDialog openFileDialog = new System.Windows.Forms.OpenFileDialog();
openFileDialog.Filter = "可执行文件(*.exe)|*.exe";
openFileDialog.FilterIndex = 1;
openFileDialog.RestoreDirectory = true;
openFileDialog.Title = "选择播放器";
openFileDialog.Multiselect = false;//选择单个
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
Config.PlayerPath = openFileDialog.FileName;
}WPF文件选择窗
//文件夹选择
FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();
folderBrowserDialog.SelectedPath = Config.FolderPath; //设置初始目录
if (folderBrowserDialog.ShowDialog() == DialogResult.OK)
{
Config.FolderPath = folderBrowserDialog.SelectedPath; //获取选择的文件夹的全路径名
}Newtonsoft.Json
这组件并非只是字符串转对象那么简单的基本功能，它有很多高级用法，可以设置打印格式、某些对象是否打印等等
这是就不贴代码了，可以看看其他博主写的

AutoMapper
简单的说帮助我们完成对象间的赋值，特别是实体对象类似相同属性又一堆的情况下，需要写一堆的 modelA.id = modelB.id.......，有了他们能省不少事，同样它的高级用法很多

MwvmLight.Messenger
这是在WPF中不得不用到消息穿梭器，怎么说呢，在我们这例子中，如果我在软件设置界面点了保存，需要通知主界面重新加载就用到它了，当然他可以用在任何地方。
主界面注册信息接收的标识
Messenger.Default.Register
public MainViewModel()
{
VideoList = new ObservableCollection<CardModel>();
AppConfig = Common.CacheData.AppConfig;
// 通知变更
Messenger.Default.Register<string>(this, "MainView", (o) =>
{
LoadData();
});
}设置界面按标识发送通知
Messenger.Default.Send
/// <summary>
/// 重新配置文件
/// </summary>
public RelayCommand<System.Windows.Window> SaveConfigurationCommand
{
get
{
var command = new RelayCommand<System.Windows.Window>((System.Windows.Window win) =>
{
// https://www.donet5.com/Doc/12/2274
var configuration = new MapperConfiguration(cfg =>
{
cfg.CreateMap<ViewModel.AppConfigUI, Model.AppConfigModel>();
});
var mapper = configuration.CreateMapper();
CacheData.AppConfig = mapper.Map<Model.AppConfigModel>(Config);
//保存配置文件
Common.CacheData.SaveConfig();
//生成桌面图标
new Common.QuickIcon(Common.CacheData.AppConfig.AppName).SetIcon(true, Common.CacheData.AppConfig.IsAutoStart);
//通知变更
Messenger.Default.Send("", "MainView");
win.Close();
});
return command;
}
}
