资源引用、资源字典引用以及容器模板和数据模板

本文主要是介绍资源引用、资源字典引用以及容器模板和数据模板，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

一、资源引用

​ 语法：

//基本语法
pack://application:,,,/项目名称;component/文件名称  
//引用字体
<TextBlock Text="&#xe60d;" FontFamily="pack://application:,,,/WpfApp3;component/Font/#iconfont" FontSize="100"></TextBlock>
//备注：
    字体文件的属性必须是资源。

二、资源字典与样式

​ 基本语法：

//新建资源文件：Dictionary1.xaml
//引用资源文件
  <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary                     Source="pack://application:,,,/WpfApp3;component/Dictionary1.xaml"></ResourceDictionary>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>
 //备注：
    ResourceDictionary.MergedDictionaries ：合并资源文件

示例代码：

<Window x:Class="WpfApp3.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:WpfApp3"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/WpfApp3;component/Dictionary1.xaml"></ResourceDictionary>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>
    <Grid>
        <Button  Style="{StaticResource btn}"  Tag="1">
            <!--<Button.Content> 
                    <TextBlock Text="Button"></TextBlock> 
            </Button.Content>-->
        </Button>
    </Grid>
</Window>

Dictionary1.xaml代码：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:sys="clr-namespace:System;assembly=System.Runtime">
    <sys:String x:Key="text">Button</sys:String>
    <Style TargetType="Button" x:Key="btn">
        <Style.Setters>
            <Setter Property="Width" Value="100"></Setter>
            <Setter Property="Height" Value="100"></Setter>
            <Setter Property="HorizontalAlignment" Value="Center"></Setter>
            <Setter Property="VerticalAlignment" Value="Center"></Setter>
            <Setter Property="BorderBrush" Value="Black"></Setter>
            <Setter Property="BorderThickness"  Value="1"></Setter>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate>
                        <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" >
                            <TextBlock Text="buttton" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}" x:Name="txt"></TextBlock>
                        </Border>
                        <ControlTemplate.Triggers >
                            <Trigger Property="BorderThickness" Value="1">
                                <Setter Property="FontSize" Value="30" TargetName="txt"></Setter>
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate> 
                </Setter.Value>  
            </Setter>   
        </Style.Setters>
        <Style.Triggers>
            <Trigger Property="Tag" Value="1">
                <Setter Property="BorderThickness" Value="5"></Setter>
                <Setter Property="BorderBrush" Value="Red"></Setter>
            </Trigger>
        </Style.Triggers>
    </Style>
</ResourceDictionary> 
//备注：
    Tag ：设置标签值   可以存放任何值
    TargetName：在控件模板中给哪个Name设置样式。

三、容器模板与数据模板

<Window x:Class="WpfApp3.Window1"
        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:WpfApp3"
        mc:Ignorable="d"
        Title="Window1" Height="450" Width="800">
    <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/WpfApp3;component/Dictionary2.xaml"></ResourceDictionary> 
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary> 
    </Window.Resources>
    <Grid>
        <ScrollViewer>
            <ListView ItemsSource="{StaticResource per}"  AlternationCount="2">
                 <!--容器样式-->
                <ListView.ItemContainerStyle>
                    <Style TargetType="ListViewItem">
                        <Style.Triggers>
                            <Trigger Property="ItemsControl.AlternationIndex"  Value="1">
                                <Setter Property="Background" Value="Orange"></Setter>
                            </Trigger>
                        </Style.Triggers>
                    </Style>
                </ListView.ItemContainerStyle>
                <!--样式选择器-->
                <ListView.ItemTemplateSelector>
                    <local:ListViewTemplateSelector NoTemp="{StaticResource NoTemp}" 
                                                    Temp="{StaticResource Temp}">
                    </local:ListViewTemplateSelector>
                </ListView.ItemTemplateSelector>
                <ListView.ItemsPanel>
                    <!--容器模板-->
                    <ItemsPanelTemplate>
                        <StackPanel></StackPanel>
                    </ItemsPanelTemplate>
                </ListView.ItemsPanel> 
            </ListView>
        </ScrollViewer>
    </Grid>
</Window>

备注：
  AlternationCount： 比如：值=2  已两个为一组进行循环。
  ItemsControl.AlternationIndex: 比如：值=1  下标为1的进行样式设置。

资源文件

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

using System.Threading.Tasks;

namespace WpfApp3
{
    public class Person
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public int Age { get; set; }
    }
}

namespace WpfApp3
{
    public class ListViewTemplateSelector:DataTemplateSelector
    {
        public DataTemplate NoTemp { get; set; }
        public DataTemplate Temp { get; set; }

        /// <summary>
        /// 选择器

        public override DataTemplate SelectTemplate(object item, DependencyObject container)
