Wanting to splite the following

 var options = Model.Value<IEnumerable<string>>("robotMetaTagDropdown");

    foreach (var option in options)
    {
        @option
    }

But if I do this:

var options = Model.Value<IEnumerable<string>>("robotMetaTagDropdown").ToString().Split(",");

I get the following error:

cannot convert from 'string' to 'char'

I've been digging throug Google but with no success. Has anyone comma separated the dropdown values from backend?
