如何在WPF应用程序中使用标准的Windows警告/错误图标?

I'm making a custom error dialog in my WPF app and I want to use a standard windows error icon. Can I get the OS-specific icon from WPF? If not, does anyone know where to get .pngs with transparency of them? Or know where in Windows to go extract them from?

我在我的WPF应用中创建了一个自定义错误对话框，我想使用一个标准的windows错误图标。我可以从WPF上获得os特定的图标吗?如果没有，有没有人知道在哪里可以找到透明的。pngs ?或者知道在Windows中从哪里提取它们?

So far my searches have turned up nothing.

到目前为止，我的搜索一无所获。

There is a SystemIcons class, but it need adjustment for WPF needs (i.e. converting Icon to ImageSource).

有一个systemicon类，但是它需要根据WPF的需要进行调整(即将图标转换为ImageSource)。

The vast majority of developers out there don't know that Visual Studio comes with an Image Library. So here goes two links that highlight it:

绝大多数开发人员都不知道Visual Studio附带了一个图像库。这里有两个链接，突出显示:

This is how I used a System icon in XAML:

这就是我在XAML中使用系统图标的方式:

xmlns:draw="clr-namespace:System.Drawing;assembly=System.Drawing"
...
<Image Source="{Binding Source={x:Static draw:SystemIcons.Warning},
        Converter={StaticResource IconToImageSourceConverter},
        Mode=OneWay}" />

I used this converter to turn an Icon to ImageSource:

我用这个转换器将图标转换为ImageSource:

public class IconToImageSourceConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        var icon = value as Icon;
        if (icon == null)
        {
            Trace.TraceWarning("Attempted to convert {0} instead of Icon object in IconToImageSourceConverter", value);
            return null;
        }

        ImageSource imageSource = Imaging.CreateBitmapSourceFromHIcon(
            icon.Handle,
            Int32Rect.Empty,
            BitmapSizeOptions.FromEmptyOptions());
        return imageSource;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

In Visual Studio, use File + Open + File and select c:\windows\system32\user32.dll. Open the Icon node and double-click 103. On my machine that's the Error icon. Back, right-click it and select Export to save it to a file.

在Visual Studio中，使用File + Open +文件并选择c:\windows\system32\user32.dll。打开图标节点，双击103。在我的机器上，这是错误的图标。返回，右键单击它并选择Export将其保存到文件中。

That's the iffy way. These icons are also available in Visual Studio. From your Visual Studio install directory, navigate to Common7\VS2008ImageLibrary\xxxx\VS2008ImageLibrary.zip + VS2008ImageLibrary\Annotations&Buttons\ico_format\WinVista\error.ico. The redist.txt file in the Visual Studio install directly explicitly gives you the right to use this icon in your own application.

这是不确定的。这些图标也可以在Visual Studio中使用。从Visual Studio安装目录中导航到Common7\VS2008ImageLibrary\xxxx\VS2008ImageLibrary。zip + VS2008ImageLibrary \ Annotations&Buttons \ ico_format \ WinVista \ error.ico。redist。Visual Studio安装中的txt文件直接显式地允许您在自己的应用程序中使用此图标。

p/invoke LoadImage with the OIC_ERROR (other icons available, but you wanted the error/stop icon), you need the LR_SHARED flag.
p/调用LoadImage并带有OIC_ERROR(其他图标可用，但是需要error/stop图标)，需要LR_SHARED标志。
If you want a different size, p/invoke CopyImage
如果需要不同的大小，请p/invoke CopyImage
Call System.Drawing.Icon.FromHandle with the IntPtr you got from LoadImage
System.Drawing.Icon打电话。从LoadImage得到的IntPtr
For GDI+, Draw your Drawing.Icon, or Clone it for later use.
对于GDI+，画出你的图画。图标，或克隆它供以后使用。
For WPF, turn it into a BitmapSource
对于WPF，将它转换为位图源
p/invoke DestroyIcon if you used CopyImage
如果你使用的是CopyImage，那么就调用毁灭图标。

You can use .NET's SystemIcons class for roughly the first three steps if the default size is ok, see modosansreves answer

如果默认大小合适，您可以使用.NET的systemicon类来完成前三个步骤，请参阅modosansreves的回答

So it could be as simple as:

所以可以这么简单:

 Imaging.CreateBitmapSourceFromHIcon(SystemIcons.Error.Handle)

#6

Use this:

用这个:

using System;
using System.Drawing;
using System.Windows;
using System.Windows.Interop;
using System.Windows.Markup;
using System.Windows.Media.Imaging;

using Extensions
{
    [ContentProperty("Icon")]
    public class ImageSourceFromIconExtension : MarkupExtension
    {
        public Icon Icon { get; set; }

        public ImageSourceFromIconExtension()
        {
        }

        public ImageSourceFromIconExtension(Icon icon)
        {
            Icon = icon;
        }

        public override object ProvideValue(IServiceProvider serviceProvider)
        {
            return Imaging.CreateBitmapSourceFromHIcon(Icon.Handle, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
        }
    }
}

Don't forget to add System.Drawing reference to your project from global location.

不要忘记添加系统。从全局位置绘制对项目的引用。

Then use this in your xaml:

然后在你的xaml中使用这个:

<WindowOrSomething x:Class="BlaBlaWindow"
    xmlns:draw="clr-namespace:System.Drawing;assembly=System.Drawing"
    xmlns:ext="clr-namespace:Extensions">
    <Image Source="{ext:ImageSourceFromIcon {x:Static draw:SystemIcons.Error}}"/>
</WindowOrSomething>

Can't you simply use Windows API?

你不能简单地使用Windows API吗?

Delphi Example:

Delphi的例子:

procedure TForm1.FormClick(Sender: TObject);
var
  errIcon: HICON;
begin
  errIcon := LoadIcon(0, IDI_ERROR);
  DrawIcon(Canvas.Handle, 10, 10, errIcon)
end;

#8

You can draw it like this:

你可以这样画:

Graphics g = this.CreateGraphics();
g.DrawIcon(SystemIcons.Question, 40, 40);

#9

use SystemIcons and convert them to an ImageSource like so:

使用systemicon并将它们转换为ImageSource，如下所示:

try   
{
    var temp = SystemIcons.WinLogo.ToBitmap();  //Your icon here
    BitmapImage bitmapImage = new BitmapImage();
    using (MemoryStream memory = new MemoryStream())
    {
       temp.Save(memory, ImageFormat.Png);
       memory.Position = 0;
       bitmapImage.BeginInit();
       bitmapImage.StreamSource = memory;
       bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
       bitmapImage.EndInit();
    }
    this.Icon = bitmapImage;
}
catch (Exception ex)
{
    this.Icon = null;
}

Convert SystemIcons.Error etc to .png (maintains transparency) then add output to resources and use as usual in WPF Image control.

SystemIcons进行转换。错误等等。png(保持透明度)然后将输出添加到资源中，并在WPF图像控制中使用。

    System.Drawing.SystemIcons.Error.ToBitmap().Save("Error.png", System.Drawing.Imaging.ImageFormat.Png);
