WPF User Control Library 制作用户控件库（时间控件）并且引用（一）

首先创建一个User Control Library工程，工程名为UserTimeEditer

控件库工程程序集如下

 UserControl1.xaml 前台文件如下：

<UserControl x:Class="UserTimeEditer.UserControl1"
             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" 
             >
    <Border   BorderThickness="1" BorderBrush="#FFABADB3" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"  >
        <StackPanel   Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center" >
            <TextBox  Text="{Binding Hour,StringFormat={}{0:00}}" FontSize="{Binding FontTime}" BorderThickness="0" HorizontalAlignment="Center" VerticalAlignment="Stretch" />
            <TextBlock Text=" : " HorizontalAlignment="Center" FontSize="{Binding FontTime}" VerticalAlignment="Center"/>
            <TextBox  Text="{Binding Minute,StringFormat={}{0:00}}" FontSize="{Binding FontTime}" BorderThickness="0" HorizontalAlignment="Center" VerticalAlignment="Center" />
            <TextBlock Text=" : " HorizontalAlignment="Center" FontSize="{Binding FontTime}" VerticalAlignment="Center"/>
            <TextBox  Text="{Binding Second,StringFormat={}{0:00}}" FontSize="{Binding FontTime}" BorderThickness="0" HorizontalAlignment="Center" VerticalAlignment="Center" />
        </StackPanel>
    </Border>
</UserControl>

UserControl1.xaml.cs 后台代码如下：

using System;
using System.ComponentModel;
using System.Runtime.CompilerServices;
using System.Windows.Controls;

namespace UserTimeEditer
{
    /// <summary>
    /// Interaction logic for UserControl1.xaml
    /// </summary>
    public partial class UserControl1 : UserControl , INotifyPropertyChanged
    {
        public UserControl1()
        {
            InitializeComponent();
            DataContext = this;
        }

        private int _fontTime = 0;
        public int FontTime
        {
            get { return _fontTime; }
            set { _fontTime = value; NotifyPropertyChanged(); }
        }
        private int _Hour = 0;
        public int Hour
        {
            get { return _Hour; }
            set { _Hour = value; NotifyPropertyChanged(); }
        }

        private int _Minute = 0;
        public int Minute
        {
            get { return _Minute; }
            set { _Minute = value; NotifyPropertyChanged(); }
        }

        private int _Second = 0;
        public int Second
        {
            get { return _Second; }
            set { _Second = value; NotifyPropertyChanged(); }
        }

        public event PropertyChangedEventHandler PropertyChanged;
        private void NotifyPropertyChanged([CallerMemberName] String propertyName = "")
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            }
        }
    }
}

 编译该控件库程序集，编译成功生成UserTimeEditer.dll动态链接库

再创建一个WPF App工程来测试一下，工程名为：TestUserTimeEditer

整体项目如下：

 右击App程序集的依赖项，点击添加引用

在项目->解决方案下找到刚才生成的UserTimeEditer.dll动态链接库，点击确定添加进来

 

 在工具箱内就能找到刚才生成的时间控件，此时就能把该控件拖进MainWindow.xaml布局器中

MainWindow.xaml前台文件如下：

<Window
        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:local="clr-namespace:TestUserTimeEditer"
        xmlns:UserTimeEditer="clr-namespace:UserTimeEditer;assembly=UserTimeEditer" x:Class="TestUserTimeEditer.MainWindow"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <StackPanel>
        <UserTimeEditer:UserControl1 x:Name="TimeEditer" FontTime="30">
        </UserTimeEditer:UserControl1>
        <Button Content="读时间" Click="btnClickReadTime"/>
    </StackPanel>
</Window>

MainWindow.xam.cs后台代码如下:

using System.Windows;

namespace TestUserTimeEditer
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void btnClickReadTime(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("时间为： " + TimeEditer.Hour.ToString("00") + " : " + TimeEditer.Minute.ToString("00") + " : " + TimeEditer.Second.ToString("00"));
        }

    }
}

运行结果如下：
