An explicit conversion exists

perhaps I will stay with programming

program is hobby that make some money as side effect

List<Point> listPoint = new List<Point>();
Point pointToAdd;
pointToAdd = new Point(1, 1);
for (int i = 0; i <= 10; i++)
{
    if (!listPoint.Contains(pointToAdd))
    {
        listPoint.Add(pointToAdd);
    }
}
Console.WriteLine(listPoint.Count);

List<Point> CleanList(List<Point> listPoint)
{
    List<Point> cleanList = new List<Point>();
    foreach (Point currentPoint in listPoint)
    {
        if (!(cleanList.Contains(currentPoint)))
        {
           cleanList.Add(currentPoint);
        }
    }
return cleanList;
}
