Q: How can I assign values to attributes of an object?

Recently, I have just come into contact with "entity classes ".
There is a question, that is, the issue of assigning values to the attributes of an object.
For example, I have a student object class. Its attributes include studentid, studentname, studentsex, studentclass, and so on.
I need to assign a value to the corresponding lable in page_load:
For example:
This. lbl_studentid.text = student. studentid;
This. lbl_studentname.text = student. studentname;
This. lbl_studentsex.text = student. studentsex;
This. lbl_studentclass.text = student. studentclass;
.......
I wonder if the object class should be used like this?
When assigning values to attributes of an object, do I use the table in dateset to assign values to the expected attributes?
So what are the advantages of assigning values to controls using tables in dateset?
