C# 从结构中获取图片框

C# Getting pictureboxes from Struct

我想获取在结构中创建的对象。不过,显示代码会更好地解释它。

 private void Obstacle() 
    {

        obstacle_pos_x = obstacle_random_x.Next(1000);
        obstacle_pos_y = obstacle_random_y.Next(700);
        picture = new PictureBox 
        {
            Name = "pictureBox" + obstacle_numb,
            Size = new Size(32, 32),
            Location = new Point(obstacle_pos_x,obstacle_pos_y),               
            BackColor = Color.Black,
        };
        this.Controls.Add(picture);       
    }

这是 Obstacle 方法内部的结构。如您所见,此方法创建了图片框,我想将它们拉入 KeyPressEvents。比如,如果我按 W,所有由 struct 创建的图片框都必须移动 -10(y 轴)。

else if (e.KeyCode == Keys.W)
        {
            y -= chrspeed;
            obstacle_numb++;
            Obstacle();
            for (int i = 0; i <= obstacle_numb; i++)
            {

            }
        }

好吧,这次活动。但它只是创建图片框。 For 循环是空的,因为我不知道该怎么做。我只是想做那样的事情,

图片+obstacle_numb.Location = new Point(x,y); (我需要这张图片+obstacle_numb组合。)

但也知道这是不可能的。我想到了foreach,但我不知道如何使用它。如果修复,也许这样的东西可以工作。

foreach(PictureBox objects from picture) //It doesn't work too.

我现在被卡住了,等待你的帮助。提前致谢。

最简单的方法是迭代 PictureBox 类型的所有子控件:

...
foreach (var pict in this.Controls.OfType<PictureBox>())
{
    // pict is now a Picturebox, you can access all its properties as you have constructed it
    // the name was constructed that way: Name = "pictureBox" + obstacle_numb,
    if (pict.Name != "pictureBox1")
    {
        pict.Location = new Point(pict.X, pict.Y-10);
    }
}
