解决方法
在尝试了线程
WPF listbox. Skip underscore symbols in strings中的所有解决方案之后,我似乎没有在MenuItems上工作,我这样做了：
public class EscapeMnemonicsStringConverter : IValueConverter
{
public object Convert(object value,Type targetType,object parameter,CultureInfo culture)
{
string str = value as string;
return str != null ? str.Replace("_","__") : value;
}
public object ConvertBack(object value,CultureInfo culture)
{
throw new NotImplementedException();
}
}
