对 ObservableCollection 进行排序
假设我有员工类的 ObservableCollection
public ObservableCollection<Employee> employeeCollection = new ObservableCollection<Employee>();
public class Employee
{
public string FirstName { get; set; }
public string LastName { get; set; }
public double MobileNumber { get; set; }
public string City { get; set; }
public int Age { get; set; }
public Employee() {}
}
，现在我正在尝试对 ObservableCollection （“employeeCollection”）进行排序 通过用户从组合框中进行适当的选择[它将是…按名字排序…按手机号码排序等…]..
并且需要返回排序的可观察集合…. 意味着它不应该采用“var”的形式，而应该是 ObservableCollection
所以我可以将它分配回 “ItemsControl” 的 “ItemsSource” 属性…
谢谢……
Suppose I have ObservableCollection of employee class
public ObservableCollection<Employee> employeeCollection = new ObservableCollection<Employee>();
public class Employee
{
public string FirstName { get; set; }
public string LastName { get; set; }
public double MobileNumber { get; set; }
public string City { get; set; }
public int Age { get; set; }
public Employee() {}
}
now I am trying to sort the ObservableCollection (“employeeCollection”)
by appropriate selection by user from combobox[it will be….Sort By FirstName….Sort By MobileNumber etc…]..
and it is required to get back sorted observable collection….
Means it should not be in form of “var” it should beObservableCollection<Employee>
So I can assign back it to “ItemsSource” property of “ItemsControl”…
Thanks……

您可以对集合的视图进行排序，而不是对集合本身进行排序：
然后您可以使用 CollectionViewSource 作为 ItemSource：
You can sort the view of the collection rather that sorting the collection itself:
And then you can use the CollectionViewSource as ItemSource:
我认为 PVitt 可能有最好的解决方案...但是，我确实找到了这个
SortedObservableCollection 类也许可以提供帮助？

我实现了一个
ObservableCollectionView，它支持使用 lambda 进行排序和过滤（类似于 LINQ，但实时）和项目跟踪：https://mytoolkit.codeplex.com/wikipage?title=ObservableCollectionView

您不需要自己排序，而是可以让 WPF 为您完成排序。例如，请参阅 SortDescription。
You don't need to sort yourself, but can let WPF do it for you. See SortDescription, for example.
