点击了一个生成的图片框。我想知道哪一个被点击了。我想知道“我”。点击完成后工人的价值。 [英] One of the resulting pictureboxes was clicked. I want to know which one is clicked. I want to know the "I" value of the worker when the click is done.

问题描述

for (int i = 0; i < 3; i++)
 {
     worker[i] = new PictureBox();
     worker[i].Name = "isci-" + i.ToString();
     worker[i].Location = new Point(10 + i, 20);
     worker[i].ImageLocation = "D:\\Proje Resim\\Folder.PNG";
     worker[i].Width = 150;
     worker[i].Height = 120;
     worker[i].Visible = true;
     worker[i].BackColor = Color.Transparent;
     worker[i].SizeMode = PictureBoxSizeMode.StretchImage;

     flowLayoutVideo.Controls.Add(worker[i]);
     worker[i].DoubleClick += new EventHandler(workerStart_Click);

推荐答案

最简单的方法是使用PictureBox的Tag属性（所有Control派生类都有Tag属性）并将其设置为i的值：

Easiest way is to use the Tag property of the PictureBox (all Control derived classes have a Tag property) and set it to the value of i:

worker[i] = new PictureBox();
worker[i].Tag = i;
worker[i].Name = "isci-" + i.ToString();

然后在Click处理程序中：

Then in the Click handler:

void allPictureBoxes_Click(object sender, EventArgs e)
    {
    PictureBox p = sender as PictureBox;
    if (p != null)
        {
        int i = (int) p.Tag;
        ...
        }
    }
