为c＃windows应用程序提供自定义样式

Question

I am wondering if there is a way to customize style of windows forms application built in visual studio using c#. I have searched through the internet and couldn't find simple solution for overriding default view of the layout. Is there a way to change layout with cascading style sheets? Thanks in advance.

Answer 1

Windows Forms apps do not support CSS , it is used when developing websites.

In Winforms you are limited to the styles which are listed in Properties window in GUI editor, unless you'd like to override OnPaint event and do custom drawing.

Some examples are:

If you are looking for more customizable solution, you can turn to WPF.

you can find answer here..

or

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        // Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
    }
}

You can use a static resource such as this.

Inside button tag Style="{DynamicResource sty3dBtn}" (You can set margins here too but sometimes thats best to do for each button depending on your own needs)

You can use xml styling. The button is set to have a dropshadow and gradient and lights up when pressed etc. As I wanted to reuse these effects with similar buttons I created a reusable style in my Application.xaml enclosed in Application - Application.Resources tags and referenced its x:Key in style attribute of the button I wanted the effect on. You can do this on each page you choose but I think it can be better to place in a common area so its reusable throughout the scope of the class you place it in. Note the Target Type must match.

I'll post snippet of the xml style it turns a regular button into one with 3d effect. You can reference this as many times as you need. It cuts down on inline code clutter too so makes the page more readable in my opinion.

    <Style x:Key="sty3dBtn" TargetType="Button">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Grid>
                        <Rectangle x:Name="GelBackground" Opacity="1" RadiusX="9" RadiusY="9"
                               Fill="{TemplateBinding Background}" StrokeThickness="0.35"
                                   RenderTransformOrigin="0.5,0.5">
                            <Rectangle.Stroke>
                                <LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
                                    <GradientStop Color="YellowGreen" Offset="0" />
                                    <GradientStop Color="Green" Offset="1" />
                                </LinearGradientBrush>
                            </Rectangle.Stroke>
                        </Rectangle>
                        <Rectangle x:Name="GelShine" Margin="2,2,2,0" VerticalAlignment="Top"
                                   RadiusX="6" RadiusY="6" Opacity="1" Stroke="Transparent" Height="15px">
                            <Rectangle.Fill>
                                <LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
                                    <GradientStop Color="Yellow" Offset="0"/>
                                    <GradientStop Color="Transparent" Offset="1"/>
                                </LinearGradientBrush>
                            </Rectangle.Fill>
                        </Rectangle>
                        <ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center"/>
