导读:我有两个列表 ListString l_lstNames = new ListString { "A1","A3","A2","A4","A0" };ListTest l_lstStudents = new ListTest { new Test { Age = 20,Name = "A0" },new Test { Age = 21,Name = "A1" },new Test { Age = 22,Name = "A2" },new Test { Age =
我有两个列表
List<String> l_lstNames = new List<String> { "A1","A3","A2","A4","A0" }; List<Test> l_lstStudents = new List<Test> { new Test { Age = 20,Name = "A0" },new Test { Age = 21,Name = "A1" },new Test { Age = 22,Name = "A2" },new Test { Age = 23,Name = "A3" },new Test { Age = 24,Name = "A4" },}; 测试就是类 public class Test { public String Name; public Int32 Age; } 我需要根据l_lstNames对l_lst学生中的项进行排序.所以排序的列表会像, List<Test> l_lstStudents = new List<Test> { new Test { Age = 21,new Test { Age = 20,}; 现在我正在用这样做. 喜欢 >创建一个新的测试对象列表. 请帮我以简单的方式(Linq或Lambda) 解决方法
尝试这个:
l_lstStudents = l_lstStudents.OrderBy(s => l_lstNames.IndexOf(s.Name)).ToList() 我觉得这个意思很清楚. (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
