linq查询怎么返回指定列生成匿名类

linq查询如何返回指定列生成匿名类.
var niming = from s in strlist select new { s.Studentid, s.Studentname }; //获取strlist中student对象的两个属性


  var niming = strlist.Select();//如何在这里通过select限制查询出的列..跟上面的一样,只是换了一种方式

[解决办法]

C# code

//你上面是在转LIst?new {m.Stuendid,m.Studentname}).ToList();
[解决办法]
class Student  
{  
   public int Age { get; set; }  
   public string Name { get; set; }  
public bool Sex { get; set; }  
}  
private List <Student> GetStudents()  
   {  
       List <Student> students = new List <Student> {  
           new Student{ Name="a", Age=1, Sex =true},  
           new Student{ Name="b", Age=2, Sex =false},  
       };  
       return students;  
   }  
List <Student>  tmp = GetStudents.Where(p=>p.Sex ==True);  
List<Student> studentList = GetStudents
var stu2 =from st in stulist
    select new {name = st.Name, age= st.Age}
