使用转换器，将字符串值做处理：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | using System;using System.Collections.Generic;using System.Globalization;using System.Linq;using System.Text;using System.Windows;using System.Windows.Data;namespace Controls.Converters{ public class StringSpaceConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { string str = string.Empty; if(!string.IsNullOrWhiteSpace((string)value)) { str = (string)value; var a = System.Text.RegularExpressions.Regex.Replace(str, @"(\w{4})", "$1 ").Trim(' '); return a; } return str; } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } }} |
页面上使用静态资源，引用此转换：
<convert:StringSpaceConverter x:Key="StringSpaceConverter" />
<TextBlock FontSize="48" HorizontalAlignment="Left" Foreground="{DynamicResource CardFontForBrush}" Text="{Binding DataModel.vip_no,Converter={StaticResource StringSpaceConverter}}" />
