关闭材料设计对话框

Question

我有材料设计对话框：<materialDesign:DialogHost CloseOnClickAway="True" IsOpen="{Binding IsOpenDialogAddingEP, UpdateSourceTrigger=PropertyChanged}">...</materialDesign:DialogHost><Button Command="{Binding CloseDialogAddingEPCommand}"/>我想在单击按钮时关闭对话框，在代码后面：public ICommand CloseDialogAddingEPCommand { get; private set; }public MyPage(){    InitializeComponent();    DataContext = this;    CloseDialogAddingEPCommand = new RelayCommand(CloseDialogAddingEP);}void CloseDialogAddingEP(){     IsOpenDialogAddingEP = false;}private bool isOpenDialogAddingEP;public bool IsOpenDialogAddingEP{   get { return isOpenDialogAddingEP; }   set   {        isOpenDialogAddingEP = value;        OnPropertyChanged("IsOpenDialogAddingEP");    }}public event PropertyChangedEventHandler PropertyChanged;protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null){            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));}但按钮没有任何作用，你能告诉我为什么吗？

您是否添加了：

public partial class Window:Window, INotifyPropertyChanged
