如何在现代 window wpf 中设置表单图标

Question

我正在使用现代 UI 模板开发 Visual Studio 2013 WPF 应用程序。当我设置表单图标然后调试时，出现错误：

这是我的源代码：

    <mui:Link DisplayName="settings" Source="/Pages/SettingsPage.xaml" />
    <mui:Link DisplayName="help" Source="https://github.com/firstfloorsoftware/mui" />
</mui:ModernWindow.TitleLinks>

当我删除 "Icon" 属性时，调试工作正常但没有图标出现在 Windows 任务栏中。请帮助我

Answer 1

我发现在代码隐藏中设置图标属性更容易。

例如

public partial class MainWindow 
    : ModernWindow
{
    public MainWindow()
    {
        InitializeComponent();
        Icon = DieuBeni002.Properties.Resources.logo.ToImageSource();
    }
}

我们需要转换徽标，因为它返回为 System.Drawing.Bitmap 类型，而 Icon 需要 System.Windows.Media.ImageSource 类型。

internal static class IconUtilities
{
    public static ImageSource ToImageSource(this Bitmap bitmap)
    {
        if (bitmap == null) throw new ArgumentNullException("bitmap");

        return Imaging.CreateBitmapSourceFromHBitmap(bitmap.GetHbitmap(), IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
    }
}

P.S。要从图标类型转换，您可以使用建议解释 here。
