Using foreach with two types of conditions in c#

Question

I used dropdown for search. The text value should different from the value. So, I created 2 types of methods:

    List<string> lstRoles = new List<string>();
    lstRoles = _repository.GetRolesForFindJobseekers();
    List<string> lstFunctions = new List<string>();
    lstFunctions = _repository.GetFunctionsForRolesFindJobSeekers();


    List<SelectListItem> selectListRoles = new List<SelectListItem>();

    int i = 1;
    foreach (string role in lstRoles)
    {

            selectListRoles.Add(new SelectListItem
            {
                Text = role,
                Value = role,
                Selected = (i == 0)
            });

            i++;

    }
    ViewData["RolesForJobSeekers"] = selectListRoles;

lstFunctions should come in the value field. How will I add this?

You could use linq and get it done in one query:

var selectListRoles =
    lstRoles
        .Zip(lstFunctions, (role, function) => new { role, function })
        .Select((rf, i) => new SelectListItem()
        {
            Text = rf.role,
            Value = rf.function,
            Selected = (i + 1 == 0),
        })
        .ToList();

ViewData["RolesForJobSeekers"] = selectListRoles;
