Question

[Display(Name="Name")]
public string StudentName { get; set; }

why use the Display attribute and how i can use them ? for what !

Answer 1

The Display attribute is used to modify the text that displays on the screen when a control is rendered for your view.

For example (in your view CSHTML file):

@Html.LabelFor(x => x.StudentName)

Will display a label with the text "Name" because of the Display attribute in your example, rather than the default value of "Student Name" had you not included the attribute. This is also true of validation messages.
