//转换输入字符串中的任何转义字符。
System.Text.RegularExpressions.Regex.Unescape(s)
//通过替换为转义码来转义最小的字符集（\、*、+、?、|、{、[、(、)、^、$、.、# 和空白）。
//这将指示正则表达式引擎按原义解释这些字符而不是解释为元字符。
System.Text.RegularExpressions.Regex.Escape(s)
XAML中使用Converter对值进行处理
<StackPanel Orientation="Horizontal" VerticalAlignment="Center" HorizontalAlignment="Center">
<TextBlock Text="{Binding Path=Authority_icon,Converter={x:Static local:ConverterUtil.StringToIconConverter}}" Style="{StaticResource IconStyle}"/>
</StackPanel>
Converter中把值String转义
public class StringToIconConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
if (value != null)
{
return Regex.Unescape(StringToUnicode(value.ToString()));
}
return value;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
/// <summary>
/// 字符串转为UniCode码字符串
/// </summary>
public static string StringToUnicode(string s)
{
if (!string.IsNullOrEmpty(s))
{
//这里把格式 转为 \ue625
return s.Replace(@"&#x",@"\u").Replace(";","");
}
return s;
}
}
