An issue with modifying the value of an object in EF ... (When the field is super many)

The general EF modifies the value of a single object, which is how I handle it.

such as: DBEntities db=new dbentities ();

Student Stu = Db.student.firstOrdefault (m=>m.id==id);

Stu.name= "SB";

stu.age=11;

......

Db. SaveChange ();

If there are fewer fields, there is no problem (there seems to be a modified method in EF, regardless of it).

What if 200 fields? Are you going to go to a. Attribute?

I can solve this problem with reflection. Concrete method See younger brother before writing essays (clone What, what deep copy, shallow copy of the trial under unsuccessful. Do not know whether to open the wrong way)

Other solutions please the great God to enlighten you!
