The best out of the box solution is using FontDialogform System.Windows.Formsassembly, but you will have to convert it's output to apply it to WPF elements.
最好的开箱即用解决方案是使用FontDialog表单System.Windows.Forms程序集，但您必须转换它的输出才能将其应用于 WPF 元素。
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;
}
Notice that winforms dialog does not support many of WPF font properties like extra bold fonts.
请注意，winforms 对话框不支持许多 WPF 字体属性，例如额外的粗体字体。
Color dialog is much easier:
颜色对话框要容易得多：
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));
}
It does not support alpha though.
虽然它不支持 alpha。

You can use classes from System.Windows.Forms, there is nothing wrong with using them. You'll probably need to convert values to WPF-specific though.
您可以使用来自 的类System.Windows.Forms，使用它们没有任何问题。不过，您可能需要将值转换为 WPF 特定的值。
Alternatively, you can implement your own dialogs or use third-party controls, see Free font and color chooser for WPF?.
或者，您可以实现自己的对话框或使用第三方控件，请参阅WPF 的免费字体和颜色选择器？.
