我想根据搜索从我的视频类中返回列表视图条目。在Videos类中，有单独的Video对象具有多个属性，如标题，视图，作者和上传日期。Xamarin自定义列表视图搜索

如何查询视频以基于搜索栏返回视频对象？最后，我希望它根据标题属性的查询返回视频对象的所有属性。

如果title.contatins（关键字）：返回视频对象

Homepage.xaml.cs：

public partial class Homepage : ContentPage 
{ 
    List<Video> Videos = new List<Video> 
     { 
      new Video 
      { 
       Title = "Video 1", 
       Author = "FedEx", 
       Views = 322, 
       Upload_DateTime = new DateTime(1996, 8, 26), 
       ImageURL = "icon.png", 

      }, 
      new Video 
      { 
       Title = "Video 2", 
       Author = "FedEx", 
       Views = 554, 
       Upload_DateTime = new DateTime(2017, 1, 23), 
       ImageURL = "icon.png", 
      }, 
      new Video 
      { 
       Title = "Video 3", 
       Author = "FedEx", 
       Views = 23, 
       Upload_DateTime = new DateTime(2012, 3, 11), 
       ImageURL = "icon.png", 
      }, 

     }; 


    public Homepage() 
    { 
     InitializeComponent(); 

     VideoListView.ItemsSource = Videos; 
    } 

    private void MainSearchBar_Pressed(object sender, EventArgs e) 
    { 
     var keyword = MainSearchBar.Text; 
     VideoListView.ItemsSource = Videos.Where(Title = keyword); 

    } 

}

Video.cs：

class Video 
{ 
    public string Title { get; set; } 

    public string Author { get; set; } 
    public int Views { get; set; } 
    public DateTime Upload_DateTime { get; set; } 
    public string ImageURL { get; set; } 
}

注意：MainSearchBar_Pressed事件处理程序是抛出荷兰国际集团我送行

解决方案：

 private void MainSearchBar_Pressed(object sender, EventArgs e) 
    { 
     var keyword = MainSearchBar.Text; 
     VideoListView.ItemsSource = Videos.Where(a => a.Title.Contains(keyword)); 

    }
