Question

I have the following method calls:

var types = CityTypeExt.GetOptions();
var statuses = CityStatusExt.GetOptions();

and the following methods:

public static class CityTypeExt
{
    public static SelectList GetOptions()
    {
        var values = EnumUtilities.GetSpacedOptions<CityType>();
        var options = new SelectList(values, "Value", "Text");
        return options;
    }
}

public static class CityStatusExt
{
    public static SelectList GetOptions()
    {
        var values = EnumUtilities.GetSpacedOptions<CityStatus>();
        var options = new SelectList(values, "Value", "Text");
        return options;
    }

}

Is there a way I could make a generic method that would combine CityTypeExt and CityStatusExt ?

Note that CityType and CityStatus are Enums.

Answer 1

Try this:

public static class CityExt
{
    public static SelectList GetOptions<T>() where T : struct, IConvertible

    {
        var values = EnumUtilities.GetSpacedOptions<T>();
        var options = new SelectList(values, "Value", "Text");
        return options;
    }

}

var types = CityExt.GetOptions<CityType>();
var statuses = CityExt.GetOptions<CityStatus>();
