如何将列表的属性与datagrid WPF的rowindex绑定

<Window x:Class="YourNamespace.YourWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Your Window" Height="450" Width="800">
    <Grid>
        <DataGrid x:Name="dataGrid" ItemsSource="{Binding YourListProperty}" SelectedIndex="{Binding SelectedIndexProperty}" />
    </Grid>
</Window>

using System.ComponentModel;

namespace YourNamespace
{
    public class YourViewModel : INotifyPropertyChanged
    {
        private List<YourItem> yourList;
        public List<YourItem> YourListProperty
        {
            get { return yourList; }
            set
            {
                yourList = value;
                OnPropertyChanged("YourListProperty");
            }
        }

        private int selectedIndex;
        public int SelectedIndexProperty
        {
            get { return selectedIndex; }
            set
            {
                selectedIndex = value;
                OnPropertyChanged("SelectedIndexProperty");
            }
        }

        public event PropertyChangedEventHandler PropertyChanged;

        protected virtual void OnPropertyChanged(string propertyName)
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

using System.Windows;

namespace YourNamespace
{
    public partial class YourWindow : Window
    {
        public YourWindow()
        {
            InitializeComponent();

            YourViewModel viewModel = new YourViewModel();
            viewModel.YourListProperty = GetYourList(); // 获取列表数据的方法

            DataContext = viewModel;
        }
    }
}
