wpf(三) 安静点

导入程序集和引用其中的空间名称

比如说做一个计算工资的组件，然后可以在程序中的其它地方也可以进行调用。

新建：

 创建一个简单的计算工资的界面：

<UserControl x:Class="MyControlLibrary.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" 
             xmlns:local="clr-namespace:MyControlLibrary"
             mc:Ignorable="d" 
             d:DesignHeight="250" d:DesignWidth="320">
    <Canvas>
        <Label Content="基本工资" Canvas.Left="23" Canvas.Top="45" Height="27" Width="62"/>
        <Label Content="岗位工资" Canvas.Left="23" Canvas.Top="103"/>
        <Label Content="实际工资" Canvas.Left="23" Canvas.Top="151"/>
        <TextBox Name="t1" Height="23" Canvas.Left="90" TextWrapping="Wrap" Text="" Canvas.Top="49" Width="120"/>
        <TextBox Name="t2" Height="23" Canvas.Left="90" TextWrapping="Wrap" Text="" Canvas.Top="105" Width="120"/>
        <TextBox Name="t3" Height="23" Canvas.Left="90" TextWrapping="Wrap" Text="" Canvas.Top="151" Width="120"/>
        <Button Content="计算" Canvas.Left="90" Canvas.Top="202" Width="120" Height="17" Click="Button_Click"/>
 
    </Canvas>
</UserControl>

界面：

 后台代码：

namespace MyControlLibrary
{
    /// <summary>
    /// UserControl1.xaml 的交互逻辑
    /// </summary>
    public partial class UserControl1 : UserControl
    {
        public UserControl1()
        {
            InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            this.t3.Text = this.t2.Text + t1.Text;
        }
    }
}

比如说我们在主界面来调用，我们先将主界面划分出4个区域：

<Window x:Class="MyWpf.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:local="clr-namespace:MyWpf"
        xmlns:sys="clr-namespace:System;assembly=mscorlib"
        mc:Ignorable="d" 
        Title="MainWindow" Height="250" Width="500">
    <Grid>
        <!--将整个界面分成2行-->
        <Grid.RowDefinitions>
            <RowDefinition></RowDefinition> 
            <RowDefinition></RowDefinition>
        </Grid.RowDefinitions>
        <!--将整个界面分成2列-->
        <Grid.ColumnDefinitions>
            <ColumnDefinition>
            </ColumnDefinition>
            <ColumnDefinition>
            </ColumnDefinition>
        </Grid.ColumnDefinitions>
    </Grid>
</Window>

界面：

 下面进行调用(前提是已经将程序集引用到主界面这个程序集中了)，在window标签中加入下面属性：

xmlns:control="clr-namespace:MyControlLibrary;assembly=MyControlLibrary"

 完整代码：

<Window x:Class="MyWpf.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:control="clr-namespace:MyControlLibrary;assembly=MyControlLibrary"
        xmlns:local="clr-namespace:MyWpf"
        xmlns:sys="clr-namespace:System;assembly=mscorlib"
        mc:Ignorable="d" 
        Title="MainWindow" Height="550" Width="500">
    <Grid>
        <!--将整个界面分成2行-->
        <Grid.RowDefinitions>
            <RowDefinition></RowDefinition> 
            <RowDefinition></RowDefinition>
        </Grid.RowDefinitions>
        <!--将整个界面分成2列-->
        <Grid.ColumnDefinitions>
            <ColumnDefinition>
            </ColumnDefinition>
            <ColumnDefinition>
            </ColumnDefinition>
        </Grid.ColumnDefinitions> 
        <control:UserControl1 Grid.Column="0" Grid.Row="0" ></control:UserControl1> 
        <control:UserControl1 Grid.Column="1" Grid.Row="0" ></control:UserControl1> 
        <control:UserControl1 Grid.Column="0" Grid.Row="1" ></control:UserControl1> 
        <control:UserControl1 Grid.Column="1" Grid.Row="1" ></control:UserControl1>
    </Grid> 
</Window>

 结果：
