使用代码浏览WPF控件模版

纯代码创建，不需要创建界面，创建WPF工程后，直接复制代码就可以使用。

当你手头没有Blend，又不记得以下这段代码，但是又想浏览控件模版的时候，就可以直接复制拿来用了。

  public partial class MainWindow : Window
    {
        ListBox lbox;
        TextBox tbox;
        Grid grid;
        public MainWindow()
        {
            InitializeComponent();
            InitializeControl();
            LoadControlTemplate();

        }

        /// <summary>
        /// 创建界面
        /// </summary>
        private void InitializeControl()
        {
            grid = new Grid();
            ColumnDefinition col1 = new ColumnDefinition();
            ColumnDefinition col2 = new ColumnDefinition();
            col1.Width = GridLength.Auto;
            grid.ColumnDefinitions.Add(col1);
            grid.ColumnDefinitions.Add(col2);

            //List
            lbox = new ListBox();
            lbox.SelectionChanged += (a, b) => { ShowControlTemplate(); };
            //TextBox
            tbox = new TextBox();
            tbox.VerticalScrollBarVisibility = ScrollBarVisibility.Auto;
            tbox.HorizontalScrollBarVisibility = ScrollBarVisibility.Auto;

            grid.Children.Add(lbox);
            grid.Children.Add(tbox);

            Grid.SetColumn(lbox, 0);
            Grid.SetColumn(tbox, 1);

            this.Content = grid;
        }

        private void LoadControlTemplate()
        {
            Type type = typeof(System.Windows.Controls.Control);
            List<Type> controlType = new List<Type>();
            System.Reflection.Assembly assembly = System.Reflection.Assembly.GetAssembly(typeof(System.Windows.Controls.Control));

            foreach (Type item in assembly.GetTypes())
            {
                if (item.IsSubclassOf(type) && !item.IsAbstract && item.IsPublic)
                {
                    controlType.Add(item);
                }
            }
            lbox.ItemsSource = controlType;
        }

        private void ShowControlTemplate()
        {
            try
            {
                Type type = (Type)lbox.SelectedItem;
                System.Reflection.ConstructorInfo info = type.GetConstructor(Type.EmptyTypes);
                Control control = (Control)info.Invoke(null);
                control.Visibility = Visibility.Collapsed;
                grid.Children.Add(control);
                ControlTemplate template = control.Template;

                System.Xml.XmlWriterSettings setting = new System.Xml.XmlWriterSettings();
                setting.Indent = true;
                StringBuilder sb = new StringBuilder();
                System.Xml.XmlWriter writer = System.Xml.XmlWriter.Create(sb, setting);
                System.Windows.Markup.XamlWriter.Save(template, writer);
                tbox.Text = sb.ToString();
                grid.Children.Remove(control);

            }
            catch (Exception ex)
            {
                tbox.Text = ex.Message;
            }
        }
    }
