Linq OrderBy字符串

Question

我有一个对象集合，我想按字母顺序按其名称属性进行排序。 我试过以下内容：

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

哪个行不通。这些项目仍按照以前相同的方式列出，而不是按字母顺序排列。

编辑

下面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); 

当考虑看看orderedMeasureStations查询结果，它看起来像以下内容： 条目开始于：

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

所以很显然不按名称排序。

我怎么没看到你class MeasureStation将永远工作

什么是_measureStation，是它this？

如果是，那么它应该是什么样子，请注意属性不能有相同的名称作为其各自的私有成员

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; } 
    } 
    } 

虽然，它等同于用自动属性类：

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

所以，我跑反对他们两个

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(); 
} 

具有得到有序输出：

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