C#列表框，每个项目的背景不同

我有xaml中的列表框：

  <ListBox Name="feedListBox" Height="758" HorizontalAlignment="Center" Margin="0,10,0,0" VerticalAlignment="Top" Width="480" ScrollViewer.VerticalScrollBarVisibility="Auto" SelectionChanged="feedListBox_SelectionChanged" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="1" Background="White">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <StackPanel VerticalAlignment="Top" Width="480">
                    <TextBlock FontWeight="Bold" FontSize="24" Name="feedTitle" TextWrapping="Wrap" Margin="12,0,0,0" HorizontalAlignment="Left" Foreground="#FF000000" Text="{Binding Title.Text, Converter={StaticResource RssTextTrimmer}}" />
                    <TextBlock Name="feedSummary" Foreground="#FF000000" TextWrapping="Wrap" Margin="12,0,0,0" Text="{Binding Summary.Text, Converter={StaticResource RssTextTrimmer}}" />
                    <TextBlock Name="feedPubDate" Foreground="#FF939393" Margin="12,0,10,10" Text="{Binding PublishDate.DateTime}" HorizontalAlignment="Right" />
                    <Border BorderThickness="1" Height="2" HorizontalAlignment="Center" VerticalAlignment="Top" Width="480" BorderBrush="Black" />
                </StackPanel>
            </DataTemplate>
        </ListBox.ItemTemplate>
  </ListBox>

如何为每个项目指定不同的背景？

向viewmodel添加一个

笔刷属性，并将
数据模板中的控件绑定到它

视图模型：

using System.ComponentModel;
using System.Windows.Media;
...
public class YourViewModel : INotifyPropertyChanged{
    ...
    private Brush _backgroundCol = Brushes.Red; //Default color
    public Brush BackgroundCol
    {
        get { return _backgroundCol; }
        set 
        {
            _backgroundCol = value;
            OnPropertyChanged("BackgroundCol");
        }
    }
    ...
}

xaml：

尝试以下操作：

公共类数据
{

公共字符串feedTitleBack{get；set；}
公共字符串摘要{get；set；}
公共字符串反馈汇总{get；set；}
公共字符串PublishDate{get；set；}
公共字符串feedPubDateBack{get；set；}
公共数据（）{}
公共数据（字符串标题、字符串feedTitleBack、字符串摘要、字符串feedSummaryBack、字符串PublishDate、字符串feedPubDateBack）
{
这个.Title=Title；
this.feedTitleBack=feedTitleBack；
这个.总结=总结；
this.feedSummaryBack=feedSummaryBack；
this.PublishDate=PublishDate；
this.feedPubDateBack=feedPubDateBack；
}
}
void loadData（）
{
List obj=新列表（）；
对象添加（新数据（“标题1”、“红色”、“摘要1”、“绿色”、“日期”、“蓝色”）；
目标添加（新数据（“标题1”、“DD4B39”、“摘要1”、“006621”、“日期”、“DAB”）；
feedListBox.ItemsSource=obj；
}

{

loadData（）；
}
为笔刷属性可能希望成为get、set的每个项目指定不同的颜色property@user1很好的一点-我已经更新了我的代码示例，以反映您的建议您解决了这个问题吗？如果是，请将对您帮助最大的答案标记为已接受答案。
<TextBlock Name="feedPubDate" Background="{Binding Path=BackgroundCol}" />

            <ListBox Name="feedListBox" Height="758" HorizontalAlignment="Center" Margin="0,10,0,0" VerticalAlignment="Top" Width="480" ScrollViewer.VerticalScrollBarVisibility="Auto" SelectionChanged="feedListBox_SelectionChanged" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="1" Background="White">
