如何在 C# 中编写动态图片框单击事件

试试这个更新的代码。

private void button1_Click(object sender, EventArgs e)
    {
        int s = 4;
        int x = 0;
        int y = 0;
        for (int i = 0; i < s; i++)
        {
            if (i == 0)
            {
                x = 38;
                y = 60;
            }
            else
            {
                y += 50;
            }
            PictureBox dynamicPicture1 = new PictureBox();
            dynamicPicture1.Tag = i;
            dynamicPicture1.Location = new Point(x, y);
            dynamicPicture1.Name = "pictureBox" + i;
            dynamicPicture1.Size = new System.Drawing.Size(30, 27);
            dynamicPicture1.ImageLocation = @"C:'Users'nxa00960'Downloads'abc.jpg";
            panel1.Controls.Add(dynamicPicture1);
            dynamicPicture1.Click += dynamicPicture1_Click;
        }
    }
    void dynamicPicture1_Click(object sender, EventArgs e)
    {
        var pictureBox = sender as PictureBox;
        switch (pictureBox.Name)
        {
            case "pictureBox0":
                //do something
                break;
            case "pictureBox1":
                //do something
                break;
            case "pictureBox2":
                //do something
                break;
            case "pictureBox3":
                //do something
                break;
            default:
                break;
        }
    }

你应该把你的event handler Method名称：

dynamicPicture1.Click += dynamicPicture1_Click; //note the name here

并在某处定义事件处理程序：

void dynamicPicture1_Click(object sender, EventArgs e) {
    throw new NotImplementedException(); //default not implemented
}

事件处理程序的名称必须相互匹配...
