我有一个对象集合,我想按它们的名称属性按字母顺序排序。
我尝试了以下方法:

List<Item> itemsToSort = dataProvider.Items.ToList();
List<Item> sortedItems = itemsToSort.OrderBy(x=>x.Name).ToList();


这不起作用。仍以与以前相同的方式列出项目,而不是按字母顺序列出。

编辑

这是一个更完整的示例:

类:

public class MeasureStation
{
    #region Properties

    public int ID
    {
        get { return _measureStation.ID; }
        set { _measureStation.ID = value; }
    }

    [Required(ErrorMessage = "Navn skal udfyldes")]
    public String Name
    {
        get { return _measureStation.Name; }
        set { _measureStation.Name = value; }
    }

    public DateTime? DateEstablished
    {
        get { return _measureStation.DateEstablished; }
        set { _measureStation.DateEstablished = value; }
    }

    public DateTime? OperationPeriodStart
    {
        get { return _measureStation.OperationPeriodStart; }
        set { _measureStation.OperationPeriodStart = value; }
    }
    .
    .
    and so on...
}


查询是:

measureStations = dataProvider.MeasureStations.ToList();
var orderedMeasureStations = measureStations.OrderBy(x => x.Name);


当查看orderedMeasureStations查询结果时,它看起来如下所示:
条目开头:

F...
S...
a...
L...


因此,显然不是按名称排序。

最佳答案

我看不出您的class MeasureStation如何运作

什么是_measureStation,它是this吗?

如果是,则应看起来像这样,请注意该属性不能与其各自的私有成员具有相同的名称

  public class MeasureStation
  {
    private int id;//private is optional as it is default
    public int ID
    {
      get { return this.id; }
      set { this.id = value; }
    }
    private String name;//private is optional as it is default
    public String Name
    {
      get { return this.name; }
      set { this.name = value; }
    }
  }


但是,它等效于具有自动属性的类:

public class MeasureStation
{
  public int ID {get;set;}
  public String Name {get;set;}
}


所以,我和他们两个都碰头

private static void Main(string[] args)
{
  List<MeasureStation> itemsToSort
    = new List<MeasureStation>()
        {
          new MeasureStation() {ID = 01, Name = "Bbbb"},
          new MeasureStation() {ID = 01, Name = "Aaaa"},
          new MeasureStation() {ID = 01, Name = "Cccc"}
        };
  List<MeasureStation> sortedItems = itemsToSort.OrderBy(x => x.Name).ToList();

  Console.WriteLine("******itemsToSort*****");
  foreach (var item in itemsToSort)
      Console.WriteLine(item.Name.ToString());

  Console.WriteLine("******sortedItems*****");
  foreach (var item in sortedItems)
        Console.WriteLine(item.Name.ToString());

  Console.ReadLine();
}


得到命令的输出:

******itemsToSort*****
Bbbb
Aaaa
Cccc
******sortedItems*****
Aaaa
Bbbb
Cccc
