倒计时控件

最近做一个WPF小项目需要使用到计时器，因此写了一个计时控件，记录下来，以便下次使用。

 

前台的XAML：

<UserControl x:Class="Test.CountDown"
             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" 
             mc:Ignorable="d" 
             d:DesignHeight="110" d:DesignWidth="150">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="43*" />
            <ColumnDefinition Width="13"/>
            <ColumnDefinition Width="43*" />
            <ColumnDefinition Width="13"/>
            <ColumnDefinition Width="43*" />
        </Grid.ColumnDefinitions>
        <TextBlock Text="00" Name="HourArea"  VerticalAlignment="Center" FontSize="30" Background="Transparent" Grid.Column="0" Foreground="DarkOrange" />
        <TextBlock Text=":" Name="HourSplitMinute"  VerticalAlignment="Center" FontSize="30" Background="Transparent" Grid.Column="1" Foreground="DarkOrange" />
        <TextBlock Text="00" Name="MinuteArea" VerticalAlignment="Center" FontSize="30" Background="Transparent" Grid.Column="2" Foreground="DarkOrange" />
        <TextBlock Text=":" Name="MinuteSplitSecond"  VerticalAlignment="Center" FontSize="30" Background="Transparent" Grid.Column="3" Foreground="DarkOrange" />
        <TextBlock Text="00"  Name="SecondArea" VerticalAlignment="Center" FontSize="30" Background="Transparent" Grid.Column="4" Foreground="DarkOrange" />
    </Grid>
</UserControl>
