【WPF】自定义数据集合绑定到UI界面

需要展示列表项，从https://github.com/jdscodelab/File-Manager-UI-Wpf这个项目，只有前端UI。复用了其文件内容列表

主要源码：

<StackPanel Orientation="Vertical">

                        <Button Style="{DynamicResource ButtonStyle1}">

                            <Button.Content>

                            <Button.Content>

                                        <TextBlock Margin="5,0,0,0" Text="Some music track" VerticalAlignment="Center" TextAlignment="Left" HorizontalAlignment="Left" FontWeight="Bold" Foreground="LightSlateGray"/>

                                    <TextBlock Grid.Column="2" Text="March 19, 2019" VerticalAlignment="Center" TextAlignment="Left" HorizontalAlignment="Left" Foreground="LightSlateGray"/>

                                    <TextBlock Grid.Column="3" Text="5 Mb" VerticalAlignment="Center" TextAlignment="Left" HorizontalAlignment="Left" Foreground="LightSlateGray"/>

                                </Grid>

                            </Button.Content>

                        </Button>

                    </StackPanel>

现在需要动态绑定数据，需要使用到数据模板，写在Resource节点里面：

<DataTemplate x:Key="UserDataTemplate">

            <Button Style="{DynamicResource ButtonStyle1}">

                <Button.Content>

                    <Grid>

                        <Grid.ColumnDefinitions>

                            <ColumnDefinition Width="*"/>

                            <ColumnDefinition Width="100"/>

                            <ColumnDefinition Width="140"/>

                            <ColumnDefinition Width="120"/>

                        </Grid.ColumnDefinitions>

                        <StackPanel Grid.Column="0" Orientation="Horizontal" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">

                            <Image Margin="5,0,0,0" Width="50" Stretch="Uniform" Source="{Binding Path=FileExtensionImg}" HorizontalAlignment="Left"/>

                            <TextBlock Margin="5,0,0,0" Text="{Binding Path=FileName}" VerticalAlignment="Center" TextAlignment="Left" HorizontalAlignment="Left" FontWeight="Bold" Foreground="LightSlateGray"/>

                        </StackPanel>

                        <TextBlock Grid.Column="1" Text="{Binding Path=ItemsCount}" VerticalAlignment="Center" TextAlignment="Left" HorizontalAlignment="Left" Foreground="LightSlateGray"/>

                        <TextBlock Grid.Column="2" Text="{Binding Path=LastModyTime}" VerticalAlignment="Center" TextAlignment="Left" HorizontalAlignment="Left" Foreground="LightSlateGray"/>

                        <TextBlock Grid.Column="3" Text="{Binding Path=FileSize}" VerticalAlignment="Center" TextAlignment="Left" HorizontalAlignment="Left" Foreground="LightSlateGray"/>

                    </Grid>

                </Button.Content>

            </Button>

        </DataTemplate>

更新后的StackPanel：

<StackPanel Orientation="Vertical">

<ItemsControl x:Name="UserList" ItemTemplate="{StaticResource UserDataTemplate}" />

 </StackPanel>

代码绑定：

UserList.ItemsSource = list;

这样做，还是方便。
