WPF add a clock to my GUI
提问by Unknown Coder
Simple Request - I want to be able to display the current time within my WPF application window. Are there free controls out there for this? Just need to display the time, nothing else.
简单请求 - 我希望能够在我的 WPF 应用程序窗口中显示当前时间。有免费的控件吗？只需要显示时间，没有别的。

You could have a label or a text block and have its content bound to System.DateTime.Now
您可以有一个标签或一个文本块，并将其内容绑定到 System.DateTime.Now

You can create an analog clock with The Gauge Libraryfrom Arction. The library is not open source but it is free, so no problems there. Download the library from their site (by requesting a link per email) and add the Arction.WPF.Gauges.dlllibrary to your project. Then add the Gauge Control to a Window. (Don't forget to add the line xmlns:agc="http://www.arction.com/gauges/")
你可以创建一个模拟时钟计图书馆从Arction。该库不是开源的，但它是免费的，所以没有问题。从他们的站点下载库（通过每封电子邮件请求链接）并将Arction.WPF.Gauges.dll库添加到您的项目中。然后将仪表控件添加到窗口。（不要忘记添加行xmlns:agc="http://www.arction.com/gauges/"）
<Window x:Class="ClockDemo.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:agc="http://www.arction.com/gauges/"
xmlns:local="clr-namespace:ClockDemo"
mc:Ignorable="d"
Title="MainWindow" Height="400" Width="400">
<Grid>
<agc:Gauge Name="Clock"/>
</Grid>
</Window>
Then all you need is some code to create a Timer that will handle each second of the clock and the styling/scales of the clock.
然后，您只需要一些代码来创建一个 Timer，它将处理时钟的每一秒和时钟的样式/比例。
