c＃为什么ListBoxItem不能显示每张图片（左侧）？

Question

我有一个ListBox，应该显示与每个项目的图片。我编写代码，当我运行它时，图片无法显示，但只显示文本。我的代码中有什么错误？我确保图像文件路径是正确的。

我想显示每个项目的文字（右侧）和图标（左侧）。

WPF：

<ListBox Name="ListTest" DisplayMemberPath="Name" HorizontalAlignment="Left" Height="358" Margin="603,38,0,0" VerticalAlignment="Top" Width="361"> 
</ListBox> 

C＃

public partial class UserControl2 : UserControl 
{ 
    public UserControl2() 
    { 
     InitializeComponent(); 
     this.LoadLogos(); 
    } 

    private void LoadLogos() 
    { 
     this.ListTest.Items.Add(new CompanyDataContext("Adobe", "Adobe is a designing tool.", "/Company Logos/testDinner.jpg")); 
     this.ListTest.Items.Add(new CompanyDataContext("Facebook", "FedEx is a social networking website.", "/Company Logos/facebook.jpg")); 
     this.ListTest.Items.Add(new CompanyDataContext("FedEx", "FedEx is a courier company.", "/Company Logos/fedex.jpg")); 

    } 

    private class CompanyDataContext 
    { 
     public CompanyDataContext(string name, string about, string image) 
     { 
      this.Name = name; 
      this.About = about; 
      this.Image = image; 
     } 

     public string Name { get; private set; } 
     public string About { get; private set; } 
     public string Image { get; private set; } 
    } 
}

您需要CompanyDataContext一个DataTemplate，因为它不从Visual继承，WPF不知道如何因此使其它调用ToString方法上这个。

这可以用aDataTemplate进行处理为ListBox

未经测试的模板：

<ListBox.ItemTemplate> 
            <DataTemplate> 
                <Border x:Name="bord" CornerRadius="5" Margin="2" BorderBrush="LightGray" BorderThickness="3" Background="DarkGray"> 
                    <StackPanel Margin="5"> 
                        <TextBlock x:Name="txt" Text="{Binding Name}" FontWeight="Bold"/> 
                        <Image Source="{Binding Image}" Height="100"/> 
                    </StackPanel> 
                </Border> 

            </DataTemplate> 
</ListBox.ItemTemplate>
