WPF 分散对齐TextBlock

用了一个UserControl实现（可以设置文字对齐方式外，单独提供一个bool量控制是否分散分散，分散对齐情况下HorizontalContentAlignment和VerticalContentAlignment失效）

内部代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;namespace Test
{/// <summary>/// UserControl1.xaml 的交互逻辑/// </summary>public partial class UTextBlock : UserControl{public UTextBlock(){InitializeComponent();}public TextDecorationCollectionTextDecorations{get { return (TextDecorationCollection)GetValue(TextDecorationsProperty);

}set { SetValue(isFensanduiqiProperty, value); }}//设置分散对齐private void setSplitAlignment(){grid1.Children.Clear();grid1.ColumnDefinitions.Clear();if (IsFenSanDuiQi){for (int i = 0; i < Text.Length; i++){ColumnDefinition cd = new ColumnDefinition();grid1.ColumnDefinitions.Add(cd);}char[] ch = Text.ToCharArray();for (int i = 0;

}

xaml界面代码：

<UserControl x:Class="Test.UTextBlock"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:local="clr-namespace:Test"mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"><Grid Name="grid1" Background="{Binding Background,RelativeSource={RelativeSource  Mode= FindAncestor,AncestorType={x:Type local:UTextBlock}}}"></Grid>
</UserControl>

<userControl:UTextBlock Name="xx1" Text="1243" Margin="64,216,169,65" IsFenSanDuiQi="true" FontSize="32" BorderThickness="2" BorderBrush="Black"/>

<userControl:UTextBlock Name="xx1" Text="1243" Margin="64,216,169,65" IsFenSanDuiQi="False" FontSize="32" HorizontalContentAlignment="Right" BorderThickness="2" BorderBrush="Black"/>
