How to add limit prices in List<IOrder> collection?

[er111222]

What is the correct code?

List<IOrder> longLimitPricesList = new List<IOrder>();
			if (longOrder != null && longOrder == order)
			{
			    longLimitPricesList.Add(longOrder.LimitPrice);  //compile error here
			}

Hello er111222,
You have created a list of IOrder and thus you have to add an IOrder only. longOrder.LimitPrice refers to a double.

List<IOrder> longLimitPricesList = new List<IOrder>();
if (longOrder != null && longOrder == order)
{
	    longLimitPricesList.Add(longOrder);  
}
