Modernizing double loops in C#?
In C#, concerning an IEnumerable, is there a better way to handle searching? The code is currently using a double for loop to search in a "radius" around the character. 
            for (int dx = -radius; dx <= radius; dx++)
            {
                for (int dy = -radius; dy <= radius; dy++)
                {
                    Vector2 loc = currentLocation + new Vector2(dx, dy);
                    if (location.Objects.ContainsKey(loc) && location.Objects[loc] is T t)
                    {
                        list.Add(t);
                    }
                }
            }
            for (int dx = -radius; dx <= radius; dx++)
            {
                for (int dy = -radius; dy <= radius; dy++)
                {
                    Vector2 loc = currentLocation + new Vector2(dx, dy);
                    if (location.Objects.ContainsKey(loc) && location.Objects[loc] is T t)
                    {
                        list.Add(t);
                    }
                }
            }
I was thinking something along the lines of: location.Objects is a SerializableDictionary<Vector2, object> Is it possible to use a Where()/Intersects()/Any()/other()? Maybe by testing overlap with a Rectangle? Rectangle bubba = new Rectangle((int)location.X, (int)location.Y, radius, radius); IEnumerable<T> shortlist = location.Objects.Where(?????);
