本文详细介绍了如何使用XAML代码实现Tab控件与按钮的动态添加、删除及交互操作，包括Tab项的创建、文本设置、按钮的事件绑定等关键步骤。通过实例演示了如何灵活地管理和响应用户操作，增强应用的交互性和用户体验。

        </sdk:TabControl>
        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="325,0,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click"/>
        <TextBox Height="23" HorizontalAlignment="Left" Margin="240,0,0,0" Name="textBox1" VerticalAlignment="Top" Width="79" />
        <ListBox Height="262" HorizontalAlignment="Left" Margin="240,38,0,0" Name="listBox1" VerticalAlignment="Top" Width="148" />
    </Grid>

string name = textBox1.Text.Trim();
            StackPanel sp1 = new StackPanel
            {
                Orientation = Orientation.Horizontal
            };
            TabItem tab = new TabItem
            {
                Name = "tab" + TabCount,
                Header = sp1
            };

            TextBlock tb1 = new TextBlock
            {
                Text = "tab" + name
            };
            Image ii = new Image
            {
                Source = new BitmapImage(new Uri("Images/QQ截图20140507193021.jpg", UriKind.Relative))
            };

            Button btn = new Button
            {
                //按钮背景是图片
                //Content = ii,
                Tag = "tab" + TabCount,
                Content = "X",
                Width = 14,
                Height = 14,
                Padding = new Thickness(0),
                BorderThickness = new Thickness(0),

            };
            sp1.Children.Add(tb1);
            sp1.Children.Add(btn);
            this.tabControl1.Items.Add(tab);
            TabCount++;
            btn.Click += new RoutedEventHandler(button_Click);
        }

        void button_Click(object sender, RoutedEventArgs e)
        {
            Button b = sender as Button;

this.Parent as TabItem).Parent as TabControl).Items.Remove((this.Parent as TabItem));

            TabItem item = this.tabControl1.FindName(b.Tag.ToString()) as TabItem;
            tabControl1.Items.Remove(item);
            TabCount--;
        }
