@Zeeshan, thanks for asking a question here.

Firstly, you need to Create relation one-to-many relation, between Order table and User Table.
For example, there must be a Primary key in Users table which is named as "Id" (as per above image), in Student(or Order) table, there must a column named as "UserId", this column should be foreign key and "Id" of User table must be primary key.

Now in the C# code, you need to fetch logged in user id, to save it in the database, looking at your above code, you should do some changes and correct code should be

public ActionResult Create( Student student)
{

if (ModelState.IsValid)
{
//Get Currently Logged in user id, don't forget to include using Microsoft.AspNet.Identity;
var UserId= User.Identity.GetUserId();

//to save UserId in model
student.User_ID_id=UserId;

db.Students.Add(student);
db.SaveChanges();
return RedirectToAction("Index");
}

return View(student);
}

That's it, it should work, thanks, upvote my answer if it works for you

as you are referring student.User_Id.Id, which is wrong, you nee to save Id of int type in Student table. So create a column of type int in Student table, save UserId in that table, suppose column name is UserId, code should be. Student.UserId=UserId. Right now you are referring User Object from Student object, which is not correct 0
