過濾器可觀察到的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>(); 

我的問題是，
PersonsNew =跳過3和Persons取4和PersonsNew存儲作爲ObservableCollection<Person> 但不爲Var

注：仔細閱讀輸出應該在ObservableCollection<Person>

編輯： 見，Persons的ObservableCollection，我已經在它的Person類增加6個成員，現在我需要從它filterd人並將其存儲在Person類的新的ObservableCollection說PersonNew 感謝。 .......

Answer 1

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

或者，更簡潔：

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

如果你有一些您可以使用collection view從人員收集中選擇人員的標準。
