无法在列表视图中显示图片

Question

你好，我有问题在列表视图中显示图片。我有一个网址的数组，我必须下载图片，但为了测试目的，我尝试从我的本地硬盘驱动器填充每行相同的图片。我可以绑定数据，但到目前为止，我可以打印到图片collumn的唯一的事情就是对象的名称，但不是图片本身（DisplayData.Image）这是我的XAML和C＃代码：

XAML

C＃

 GNews gnews = new GNews(); 
     List<NewsModel> bla = gnews.getTopNews(); 


     for (int i = 0; i < bla.Count - 1; i++) 
     { 


      DisplayData data = new DisplayData(); 
      data.Name = bla[i].title; 
      data.Value = bla[i].url; 
      ImageSource mySource = new BitmapImage(new Uri("D:\\New folder\\New folder\\other\\Wall\\010.jpg")); 
      data.Image = new Image(); 
      data.Image.Source = mySource; 

      this.testView.Items.Add(data); 

     } 
    } 
} 

public class DisplayData 
{ 
    public string Name { get; set; } 
    public string Value { get; set; } 

    public Image Image { get; set; } 

}

Answer 1

你应该结合开放的我们不是一个图像。然后

public class DisplayData 
{ 
    public string Name { get; set; } 
    public string Value { get; set; } 

    public Uri Image { get; set; } 
} 

你的循环会看起来像

for (int i = 0; i < bla.Count - 1; i++) 
    { 


     DisplayData data = new DisplayData(); 
     data.Name = bla[i].title; 
     data.Value = bla[i].url; 

     data.Image = new Uri("D:\\New folder\\New folder\\other\\Wall\\010.jpg"); 


     this.testView.Items.Add(data); 

    }
