Linq查詢過濾Observable集合中的字符串列表

Question

從Observable集合我想過濾名稱爲aaa，bbb，ccc，ddd，eee的項目。這個怎麼做？

public class Item 
{ 
public string ItemName {get; set;} 
public int ItemNumber {get; set;} 
} 

public ObservableCollection<Item> _items; 

public List<string> searchItems = new List<string>(5); 
searchItems.Add("aaa"); 
searchItems.Add("bbb"); 
searchItems.Add("ccc"); 
searchItems.Add("ddd"); 
searchItems.Add("eee"); 

我在LINQ嘗試了一下。但我不知道如何爲列表做..

var filteredItems = from item in _items 
        where _items.Any(x => x.ItemName == "aaa") 
        select x; 

Answer 1

您可以使用包含;

var filteredItems = from item in _items 
        where _items.Any(x => searchItems.Contains(x.ItemName)) 
        /*select x;*/ 
        select item;
