下面的代碼不添加矩形。任何人都能建議我錯過了什麼？ mainCanvas.Children.Add(rectangle[i]);不起作用。
RoomX.Count = 5我怎麼能去與添加所有五個矩形具有不同的寬度和高度，這是在RoomX，寬敞WPF在畫布上添加矩形
private void UserControl_Loaded(object sender, RoutedEventArgs e)
{
HProDataContext db = new HProDataContext();
var RoomX = (from d in db.rooms select d.sizex).ToList();
var RoomY = (from d in db.rooms select d.sizey).ToList();
for (int i = 0; i < RoomX.Count; i++)
{
var random = new Random();
var rectangle = new Rectangle()
{
Stroke = Brushes.Black,
Fill = Brushes.SkyBlue,
Width = Convert.ToDouble(RoomX),
Height = Convert.ToDouble(RoomY),
Margin = new Thickness(left: random.NextDouble() * 300,
top: random.NextDouble() * 150,
right: 0,
bottom: 0),
HorizontalAlignment = HorizontalAlignment.Center,
VerticalAlignment = VerticalAlignment.Center,
};
mainCanvas.Children.Add(rectangle);
}
}
