推荐答案

最好的现成解决方案是使用 FontDialog 表单 System.Windows.Forms 程序集，但是您将

The best out of the box solution is using FontDialog form System.Windows.Forms assembly, but you will have to convert it's output to apply it to WPF elements.

FontDialog fd = new FontDialog();
var result = fd.ShowDialog();
if (result == System.Windows.Forms.DialogResult.OK)
{
    Debug.WriteLine(fd.Font);

    tbFonttest.FontFamily = new FontFamily(fd.Font.Name);
    tbFonttest.FontSize = fd.Font.Size * 96.0 / 72.0;
    tbFonttest.FontWeight = fd.Font.Bold ? FontWeights.Bold : FontWeights.Regular;
    tbFonttest.FontStyle = fd.Font.Italic ? FontStyles.Italic : FontStyles.Normal;

    TextDecorationCollection tdc = new TextDecorationCollection();
    if (fd.Font.Underline) tdc.Add(TextDecorations.Underline);
    if (fd.Font.Strikeout) tdc.Add(TextDecorations.Strikethrough);
    tbFonttest.TextDecorations = tdc;
}

请注意，winforms对话框不支持许多WPF字体属性，例如超粗字体

Notice that winforms dialog does not support many of WPF font properties like extra bold fonts.

颜色对话框要容易得多：

Color dialog is much easier:

ColorDialog cd = new ColorDialog();
var result = cd.ShowDialog();
if (result == System.Windows.Forms.DialogResult.OK)
{
    tbFonttest.Foreground = new SolidColorBrush(Color.FromArgb(cd.Color.A, cd.Color.R, cd.Color.G, cd.Color.B));
}

不过它不支持alpha。

It does not support alpha though.
