C# 引用多个实例化的pictureboxes

我对C#很陌生，但如果我的语法不准确，请耐心学习。我可以用一个按钮创建一个picturebox，它会出现在屏幕上。然后我可以用鼠标下/鼠标移动功能在屏幕上移动它。然后，我点击按钮实例化另一个要创建的picturebox，并可以移动该picturebox，但当我尝试移动第一个picturebox时，第二个picturebox反而会移动，并变得疯狂。有没有一种方法可以在实例化时引用或标记这些框，以便当我单击其中任何一个框时，可以在屏幕上移动它们

public partial class Form1 : Form
{
    Point MP;
    private static Control PB;        

    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        int picSizeX = Properties.Resources.police.Width / 3;
        int picSizeY = Properties.Resources.police.Height / 3;

        PictureBox pb = new PictureBox();
        pb.Location = new Point(100, 100);
        pb.Size = new Size(picSizeX, picSizeY);
        pb.Image = new Bitmap(Properties.Resources.police);
        pb.SizeMode = PictureBoxSizeMode.StretchImage;
        Controls.Add(pb);
        pb.Tag = "veh";
        PB = pb;

        pb.MouseDown += Pb_MouseDown;
        pb.MouseMove += Pb_MouseMove;
        pb.MouseHover += Pb_MouseHover;
    }

    private void Pb_MouseHover(object sender, EventArgs e)
    {
        PB.MouseHover += PB_MouseHover;
    }

    private void PB_MouseHover(object sender, EventArgs e)
    {

    }

    private void Pb_MouseDown(object sender, MouseEventArgs e)
    {
        MP = e.Location;
    }

    private void Pb_MouseMove(object sender, MouseEventArgs e)
    {
        if (e.Button == MouseButtons.Left)
        {
           PB.Left = e.X + PB.Left - MP.X;
           PB.Top = e.Y + PB.Top - MP.Y;
        }
    }
}

实际上，不需要在类级别进行控制

在event方法中，有一个名为

对象发送方

的参数，其中包含对引发事件的控件/对象的引用

Point MP;
//private Control PB; //commented out as it is not required

public Form1()
{
    InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
     int picSizeX = Properties.Resources.police.Width / 3;
     int picSizeY = Properties.Resources.police.Height / 3;

     PictureBox pb = new PictureBox();
     pb.Location = new Point(100, 100);
     pb.Size = new Size(picSizeX, picSizeY);
     pb.Image = new Bitmap(Properties.Resources.police);
     pb.SizeMode = PictureBoxSizeMode.StretchImage;
     Controls.Add(pb);
     pb.Tag = "veh";
     //PB = pb;

     pb.MouseDown += Pb_MouseDown;
     pb.MouseMove += Pb_MouseMove;
     pb.MouseHover += Pb_MouseHover;
}

private void Pb_MouseHover(object sender, EventArgs e)
{
     Control pbObj = sender as PictureBox; //sender refers to control that raised the event
     pbObj.MouseHover += PB_MouseHover;
}

private void PB_MouseHover(object sender, EventArgs e)
{

}

private void Pb_MouseDown(object sender, MouseEventArgs e)
{
    MP = e.Location;
}

private void Pb_MouseMove(object sender, MouseEventArgs e)
{
     Control pbObj = sender as PictureBox; //sender refers to control that raised the event

     if (e.Button == MouseButtons.Left)
     {
         pbObj.Left = e.X + pbObj.Left - MP.X;
         pbObj.Top = e.Y + pbObj.Top - MP.Y;
     }
}

我想我在你写这篇文章的时候把代码放在了编辑栏里。抱歉。为什么要将

静态
控件保留在类级别？这是我试图弄明白时留下的垃圾。我想我在发帖前已经把它擦掉了。我可以吻你。这正是我一直在寻找的答案。为了理解它，我还有更多的学习要做，但它是有效的，我很高兴。非常感谢。
