我一直在尝试填充我的选择器,但我不知道如何。我看了一些在线教程,但他们是一种混乱,他们都创建了一个项目列表,我还没有这样做。
namespace FYP.ViewModels
{
public class NewGames
{
public int Id { get; set; }
public string GameTitle { get; set; }
public double Rating { get; set; }
public string ImageSource { set; get; }
}
}
●使用系统.组件模型;使用系统文本;
命名空间FYP. ViewModels {
public class NewReleasesViewModel : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
private ObservableCollection<NewGames> NewGames;
public ObservableCollection<NewGames> Games
{
get { return NewGames; }
set { NewGames = value;
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("Games"));
}
}
public NewReleasesViewModel()
{
Games = new ObservableCollection<NewGames>();
AddData();
}
private void AddData()
{
Games.Add(new NewGames
{
Id = 0,
GameTitle = "The Elder Scrolls Online",
Rating = 4.9,
ImageSource= "https://assets-prd.ignimgs.com/2022/01/05/elderscrollsonline- 1641413357689.jpg"
});
Games.Add(new NewGames
{
Id = 1,
GameTitle = "World Of Warcraft",
Rating = 4.9,
ImageSource = "https://assets-prd.ignimgs.com/2021/12/10/wow-1639126324635.jpg"
});
Games.Add(new NewGames
{
Id = 2,
GameTitle = "Star Wars: The Old Republic",
Rating = 4.9,
ImageSource = "https://assets-prd.ignimgs.com/2022/01/27/swotor-sq1-1643302998212.jpg"
});
}

你需要指定一个
ItemSource
你需要告诉它要显示哪个属性
