如何退出wpf应用程序

Question

我有一个WPF项目，它是解决方案的一部分，它是“ProjectFilesSelector”。一个名为A.的项目，如下图所示调用ProjectFilesSelector：

!!!更新：

namespace ProjectFilesSelector
{
   ...
   public class ViewModel 
   {
        ...
        public ICommand cancel
        {
            get
            {
                return new WPFExtensions.RelayCommand(_ =>
                    {
                        this.window.Visibility = Visibility.Hidden;
                        this.window.Close();

                    });
            }
        }

   }   


public partial class Window1 : Window, IDisposable
   {
        public Window1(ProjectTypes.Project pro)
        {
            InitializeComponent();

        var context = new ViewModel(this, new ATChecker.ViewModel.ProjectModel(pro));
        this.DataContext = context;
    }


...
   }

}

namespace ATCheckerView
{
    public class ViewerClientExt : INotifyPropertyChanged
    { 
        ...

    public ICommand CheckPrinciplies
    {
        get
        {
            var cmnd =
                new RelayCommand(project =>
                {
                    var proj = (ViewModel.ProjectModel)project;

                    ProjectFilesSelector.ViewModel dc;

                    using (var a = new ProjectFilesSelector.Window1(proj.project))
                    {
                        a.ShowDialog(); // cancel command was called
                        dc = (ProjectFilesSelector.ViewModel)a.DataContext;
                    }
                    ....
                    // some code 
                    // and I can still see the window of Window1. Why? 


                });

var context = new ViewModel(this, new ATChecker.ViewModel.ProjectModel(pro)); this.DataContext = context; }

public ICommand CheckPrinciplies { get { var cmnd = new RelayCommand(project => { var proj = (ViewModel.ProjectModel)project; ProjectFilesSelector.ViewModel dc; using (var a = new ProjectFilesSelector.Window1(proj.project)) { a.ShowDialog(); // cancel command was called dc = (ProjectFilesSelector.ViewModel)a.DataContext; } .... // some code // and I can still see the window of Window1. Why? });

我认为您不想退出该应用程序。您可能只想关闭窗口。 取消按钮只是将IsCancel设置为true。对于ok按钮，最好的方法是在viewmodel中创建一个事件以启动视图。
