Set all values in SelectList in C#

Question

In a SelectList object, I want that the Text property of each element of the SelectList should also be the value. For eg:

SelectList s=new SelectList(some list);
s.ElementAt(i).Value=s.ElementAt(i).Text;

Is there any way to do this APART from using a loop? Is there any inbuilt method or something like that to accomplish this?

You can use the following Constructor overload for SelectList:

public SelectList(
    IEnumerable items,
    string dataValueField,
    string dataTextField
)

You can then, provided same list member for dataValueField and dataTextField.

You mean like : new SelectList(some list, "Text", "Text"); – karan k Jun 26 '12 at 08:01
Can you inform how is your list like? Is it like List or what? – Ebad Masood Jun 26 '12 at 08:04
@karank : yes, exactly new SelectList(some list, "Text", "Text"); should work. – Ebad Masood Jun 26 '12 at 08:06

If you really want to do it without a loop, just use linq foreach (which is a loop in the background):

s.ToList().ForEach(c=>c.Text = c.Value)

He said, he does'nt want to loop through the list. – Ebad Masood Jun 26 '12 at 08:07
@ebad86 That's why I suggested linq – Oskar Kjellin Jun 26 '12 at 08:08
