是否可以创建“类”运行时？

Question

For the backend of a website, I need to fetch certain datacolumns from a database, depending on which sitesettings the user has. So there is no way of knowing which columns I will need beforehand.

Is there any way I can make a list of "objects" containing only the different types I need to return to the frontend?

For example:

The class students is stored in the database:

Students
{
string name;
int age;
double averageGrade;
string class;
Student bestFriend;
}

Let's say the user on the site wants to see only the student's name and best friend, how can I put those in an object, and put those objects in a list?

exampleStudent {name, bestFriend};

Thanks in advance!

One solution would be to store the properties using a dictionary:

Dictionary<string, object> student = new Dictionary<string, object>();
student["name"] = "Alex";
