使用转换器,将字符串值做处理:
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}}" />标签:string,object,System,value,位数,str,字符串,using,WPF From: https://www.cnblogs.com/jnyyq/p/17727953.html
