wpf 去除window默认样式

去除window最上面的一行的样式

WindowStyle="None"

添加closing事件 ，可拖拽事件

 Height="450" Width="800" Background="#2D2F2F" 
        WindowStyle="None"   ResizeMode="NoResize" MouseLeftButtonDown="Window_MouseLeftButtonDown"
        Closing="MainWindow_Closing" WindowStartupLocation="CenterScreen" Foreground="White"

        private void MainWindow_Closing(object sender, System.ComponentModel.CancelEventArgs e)
        {
            Application.Current.Shutdown();
        }
        private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            if (e.LeftButton == MouseButtonState.Pressed)
            {
                this.DragMove();
            }
        }

自己添加关闭按钮和标题

            <Grid Grid.Row="0">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition/>
                    <ColumnDefinition/>
                </Grid.ColumnDefinitions>
                <Grid Grid.Column="0">
                    <TextBlock VerticalAlignment="Center" FontSize="20" Margin="20,0,0,0">Restore Tool</TextBlock>
                </Grid>
                <Grid Grid.Column="1">
                    <Button Height="49" Width="49" HorizontalAlignment="Right"  Click="btnClose_Click">X</Button>
                </Grid>
            </Grid>

        private void btnClose_Click(object sender, RoutedEventArgs e)
        {
            this.Close();
        }
