WPF MVVM使用绑定从datagrid加载textbox中的对象

// MainViewModel.cs
public class MainViewModel : INotifyPropertyChanged
{
    private ObservableCollection<MyObject> myObjects;
    public ObservableCollection<MyObject> MyObjects
    {
        get { return myObjects; }
        set
        {
            myObjects = value;
            OnPropertyChanged(nameof(MyObjects));
        }
    }

    // 其他属性和命令...

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

// MyObject.cs
public class MyObject
{
    public string Name { get; set; }
    public int Age { get; set; }
    // 其他属性...
}
