LINQ过滤列表对象

Question

我有list对象,我需要在VB.NET中使用LINQ检查逗号分隔字符串中的id,如下所示:

dim strId as String = "1,2,3,5,"
dim myList = from objmylist where objmylist.id in (strId)

Answer 1

dim strId as String = "1,2,3,5,"
dim IDs as String() = strId.Split(",")
dim myList = from objmylist where IDs.Contains(objmylist.id) 
             select objmylist
