Add ref to list

Question

I've read places that Controls cannot be loaded into an array or list and accessed in this manner, but I'm intrigued.

My problem is as follows: I am displaying a week's worth of forecast data within my application. The forecast data is retrieved from Wunderground's JSON API and stored into an object that contains the fields necessary for display (high/low temps, condition summary, etc). My app uses the Bing maps API to perform a geocoded search and the lat/long retrieved from the Bing Maps control is passed to the request to Wunderground's service to retrieve forecast data based on a lat/long coordinate. The response contains a list of "ForecastDay" objects, which hold the forecast data for each day.

Each day is displayed in its own custom user control, and I have named them accordingly as such: forecastDay1, forecastDay2, and so on.

I'm curious as to if there's a way to add these controls to a list by reference sort of like

forecastDayControls.Add(ref forecastDay1);

so I can iterate through the controls and populate them with information based on the corresponding day, each of which has been already been put into a list by the JSON deserialization. My code is perfectly functional, but it'd be nice and pretty looking

for(int i = 0; i < forecastDayControls.Count; i++)
{
    forecastDayControls[0].ForecastDay = forecastDay[0];
}

if I could get them into a list and handle them that way, instead of going through 1 by 1 and having ugly code:

forecastDay1 = forecast.forecastDay[0];
forecastDay2 = forecast.forecastDay[1];
forecastDay3 = forecast.forecastDay[2];
forecastDay4 = forecast.forecastDay[3];
forecastDay5 = forecast.forecastDay[4];
forecastDay6 = forecast.forecastDay[5];
forecastDay7 = forecast.forecastDay[6];

Thanks!

Just do this:

forecastDayControls.Add(forecastDay1);

You do not need the ref keyword, because forecastDay1 is a class and therefore it is always passed by reference.
