Creating a select list from an array

how to find the index particular items in the list using linq?

I am trying to create a IEnumerable<SelectListItem> from an array of strings.

string[] months = { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };

model.month = months
        .Select(r => new SelectListItem{Text = r, Value = ???});

Is there a way to access their index within this query?

Solution 1

Use overloaded Enumerable.Select method:

model.month = months
    .Select((r,index) => new SelectListItem{Text = r, Value = index.ToString()});

Solution 2

Try with Enumerable.Select.

Projects each element of a sequence into a new form by incorporating the element's index.

model.month = months
        .Select((r, i) => new SelectListItem{Text = r, Value = i.ToString()});

Solution 3

Jeff this should work for you based on the example on the link that lila G posted

string[] months = { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };
var query = months.Select((r, index) => new  { Text = r, Value = index });
