WPF Datagrid点击表头排序是按编码排序的，怎么改成按拼音首字母排序？
示例代码：
ObservableCollection<Name> names = new ObservableCollection<Name>();
public MainWindow()
{
InitializeComponent();
names.Add(new Name { FirstName = "盼晴", LastName = "刘" });
names.Add(new Name { FirstName = "小柳", LastName = "张" });
names.Add(new Name { FirstName = "环", LastName = "伊" });
names.Add(new Name { FirstName = "冰岚", LastName = "宁" });
dataGrid.ItemsSource = names;
}
public class Name
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
<DataGrid Name="dataGrid" ItemsSource="{Binding}"/>
分别点击表头排序后：
- FirstName：B冰岚 - X小柳 - H环 - P盼晴（应该是B-H-P-X）
- LastName：Y伊 - L刘 - N宁 - Z张（应该是L-N-Y-Z）
如何按拼音首字母排序？
