C# 试图阻止随机生成的图片框彼此不相交

我正在windows窗体中开发一个程序，生成随机坐标点来绘制鱼。我需要鱼停止相互交叉，但我编写的代码不起作用。生成的坐标应放入矩形中，然后对照所有其他点矩形进行检查。鱼不停地交叉。知道为什么吗？

for（int i=0；i

试试下面的方法。它仅在确定该点不与任何其他鱼相交后添加该点：

Size fishSize = new Size(200, 134);
for (int i = 0; i < fishNumber;i++)
{
    Point pt;
    bool collided;
    do
    {
        collided = false;
        pt = new Point(x.Next(200, 3100), y.Next(100, 1620));
        Rectangle rcNewFish = new Rectangle(pt, fishSize);
        foreach(Point otherPt in fishPoints)
        {
            if (rcNewFish.IntersectsWith(new Rectangle(otherPt, fishSize)))
            {
                collided = true;
                break;
            }
        }
    } while (collided);
    fishPoints.Add(pt);
}

Size fishSize=新尺寸（200134）；
对于（int i=0；i

刚刚添加了它。。

Size fishSize = new Size(200, 134);
for (int i = 0; i < fishNumber;i++)
{
    Point pt;
    bool collided;
    do
    {
        collided = false;
        pt = new Point(x.Next(200, 3100), y.Next(100, 1620));
        Rectangle rcNewFish = new Rectangle(pt, fishSize);
        foreach(Point otherPt in fishPoints)
        {
            if (rcNewFish.IntersectsWith(new Rectangle(otherPt, fishSize)))
            {
                collided = true;
                break;
            }
        }
    } while (collided);
    fishPoints.Add(pt);
}
