WPF Xaml中建立集合

首先在xaml中建立集合是一个不可取的方法。学习

本方法仅做为xaml的学习。spa

本文略微无聊，主要是编写的东西都是老玩意。code

首先是定义一个类，做为你要加载集合的模型。blog

结构以下get

internal class Student { public string Name { get; set; } public int Age { get; set; } } internal class StudentList:List<Student> { } class StringCollect { public StudentList Students { get; set; } }

XAML中string

<Window.DataContext>
        <local:StringCollect  x:Name="c2"  >
            <local:StringCollect.Students>
                <local:StudentList>
                    <local:Student Age="18" Name="A1"/>
                    <local:Student Age="18" Name="A2"/>
                    <local:Student Age="18" Name="A3"/>
                </local:StudentList>
            </local:StringCollect.Students>
        </local:StringCollect>
    </Window.DataContext>
    <Grid>
        <ListBox ItemsSource="{Binding ElementName=c2,Path=Students}">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition Width="*"/>
                        </Grid.ColumnDefinitions>
                        <TextBlock>
                            <Run Text="Name:"/>
                            <Run Text="{Binding Name}"/>
                        </TextBlock>
                        <TextBlock Grid.Column="1">
                            <Run Text="Age:"/>
                            <Run Text="{Binding Age}"/>
                        </TextBlock>
                    </Grid>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
    </Grid>

那么还有别的方法吗？io

固然了，好比XAML中的X:Array关键字class

好比List

<ListBox  >
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition Width="*"/>
                        </Grid.ColumnDefinitions>
                        <TextBlock>
                            <Run Text="Name:"/>
                            <Run Text="{Binding Name}"/>
                        </TextBlock>
                        <TextBlock Grid.Column="1">
                            <Run Text="Age:"/>
                            <Run Text="{Binding Age}"/>
                        </TextBlock>
                    </Grid>
                </DataTemplate>
            </ListBox.ItemTemplate>
            <ListBox.ItemsSource>
                <x:Array Type="{x:Type local:Student}">
                    <local:Student Age="18" Name="b1"/>
                    <local:Student Age="18" Name="b2"/>
                    <local:Student Age="18" Name="b3"/>
                </x:Array>
            </ListBox.ItemsSource>
        </ListBox>

我以为在xaml建立集合是一个比较无聊的事情。
