filter Observable 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并从Persons获取4并将其存储在PersonsNew ObservableCollection<Person>             但不是为Var

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

修改 请参阅Persons ObservableCollection，我在Person类中添加了6个成员，现在我需要从中过滤掉人员并将其存储在Person类的新ObservableCollection中，并说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));

如果您有一些可以从Persons集合中选择人员的标准，您还可以使用collection view。
