namespace XamarinFormsSorting
{
    public class Person : INotifyPropertyChanged
    {
        private string name;

                    name = value;
                    OnPropertyChanged(nameof(Name));
                }
            }
        }

        public event PropertyChangedEventHandler PropertyChanged;

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

    public class MainPageViewModel
    {
        public ObservableCollection<Person> People { get; set; }

        public MainPageViewModel()

            People = new ObservableCollection<Person>
            {
                new Person { Name = "John" },
                new Person { Name = "Alice" },
                new Person { Name = "Bob" }
            };

            // 按Name属性进行排序
            People = new ObservableCollection<Person>(People.OrderBy(p => p.Name));
        }
    }
}
