过滤器可观察到的ObservableCollection - WPF

Question

ObservableCollection<Person> Persons = new ObservableCollection<Person>(); 

Persons.Add(new Person() { Name = "John 1", Age = 25, City = "New Delhi", Email ="abc@abc.com" }); 

Persons.Add(new Person() { Name = "John 2", Age = 25, City = "New Delhi", Email = "abc@abc.com" }); 

Persons.Add(new Person() { Name = "John 3", Age = 25, City = "New Delhi", Email = "abc@abc.com" }); 

Persons.Add(new Person() { Name = "John 4", Age = 25, City = "New Delhi", Email = "abc@abc.com" }); 

Persons.Add(new Person() { Name = "John 5", Age = 25, City = "New Delhi", Email = "abc@abc.com" }); 

Persons.Add(new Person() { Name = "John 6", Age = 25, City = "New Delhi", Email = "abc@abc.com" }); 

     ObservableCollection<Person> PersonsNew = new ObservableCollection<Person>(); 

我的问题是，
PersonsNew =跳过3和Persons取4和PersonsNew存储作为ObservableCollection<Person> 但不为Var

注：仔细阅读输出应该在ObservableCollection<Person>

编辑： 见，Persons的ObservableCollection，我已经在它的Person类增加6个成员，现在我需要从它filterd人并将其存储在Person类的新的ObservableCollection说PersonNew 感谢。 .......

Answer 1

ObservableCollection<Person> PersonsNew = new ObservableCollection<Person>(Persons.Skip(3).Take(4)); 

或者，更简洁：

var PersonsNew = new ObservableCollection<Person>(Persons.Skip(3).Take(4)); 

如果你有一些您可以使用collection view从人员收集中选择人员的标准。
