字符串開頭的文本修整

Question

我在WPF中有一個應用程序，我希望在我的文本框中只能看到字符串的末尾。

XAML：

<Grid Height="109" Width="126"> 
    <Grid.RowDefinitions> 
     <RowDefinition Height="166*" /> 
     <RowDefinition Height="145*" /> 
    </Grid.RowDefinitions> 
    <TextBlock Text="10000004" TextTrimming="CharacterEllipsis" TextWrapping="NoWrap" Width="40" Background="LightBlue"/> 
    <TextBlock Text="10000005" TextTrimming="CharacterEllipsis" TextWrapping="NoWrap" Width="40" Grid.Row="1" Background="LightGreen"/> 
</Grid> 

Answer 1

int Len = 4; //put this equcal to how many digits you need from last... 
//path is the actual string 
string endText = path.Substring(path.Length - Len, path.Length) 

Answer 2

As you probably have seen on MSDN，你需要創建/用自己的TextTrimmingProperty依賴屬性擴展。

Look at this擴展您的TextBlock，以便您可以創建自己的TextTrimmingProperty以不同的方式工作。
