Access static selectListItem from multiple controller-CodePudding

I have a selectListItem in a controller that I use to populate a dropdownlist.

    public List<SelectListItem> BankSelectList()
    {
        List<SelectListItem> Region = new List<SelectListItem>()
        {
                new SelectListItem { Text = "" , Value = "",Selected = true},
                new SelectListItem { Text = "North" , Value = "North"},
                new SelectListItem { Text = "East" , Value = "East"},
                new SelectListItem { Text = "North East" , Value = "North East"},
                new SelectListItem { Text = "West" , Value = "West"},
        };
        return bank;
    }

Is there a way I can reuse this in a different controller without needing to declare the list again in the other controller? I dont want to go to each controllers to update in case there are any changes in the future. I dont put it in database because the probability of changes are low, and Im also trying to save on performace.

Use the static class :

public static class DataStaticSelectList
    {
        public static List<SelectListItem> BankSelectList()
        {
            List<SelectListItem> Region = new List<SelectListItem>()
            {
            new SelectListItem { Text = "" , Value = "",Selected = true},
            new SelectListItem { Text = "North" , Value = "North"},
            new SelectListItem { Text = "East" , Value = "East"},
            new SelectListItem { Text = "North East" , Value = "North East"},
            new SelectListItem { Text = "West" , Value = "West"},
            };
            return bank;
        }
    }

And in your Controller to access the data :

var selectList = DataStaticSelectList.BankSelectList() ;

As mentioned above a static class could work. You could also make a seperate class that provides you with the required SelectListItem collection via a specific method. This potentially opens the option to use DI and populate the contents via whatever dataset your using.

public List<SelectListItem> GetBankSelectList()
{
    return new List<SelectListItem>()
    {
            new SelectListItem { Text = "" , Value = "",Selected = true},
            new SelectListItem { Text = "North" , Value = "North"},
            new SelectListItem { Text = "East" , Value = "East"},
            new SelectListItem { Text = "North East" , Value = "North East"},
            new SelectListItem { Text = "West" , Value = "West"},
    };
    
}
