委托 button1.MouseClick 事件而不是更改其控件属性

Question

嗨，这是我的第一个post，请多多包涵。 ;)

我有一个小的 class 可以在事件发生时生成按钮。我似乎无法实现的是向委托添加代码 mybutton_MouseClick 在点击时更改单个生成按钮的颜色。

所以我正在寻找一些可以执行以下操作的代码： mybutton.BackColor = Color.Red;

namespace test_addObject
{
    public partial class Form1 : Form
    {
        ButtonCreation bc = new ButtonCreation();
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            bc.createButton();
        }
    }

    public class ButtonCreation
    {
        Random rdm = new Random();

        public void createButton()
        {
            Button mybutton = new Button();
            Form1.ActiveForm.Controls.Add(mybutton);

            mybutton.Location = new Point(
                rdm.Next(Form1.ActiveForm.Width - mybutton.Width),
                rdm.Next(Form1.ActiveForm.Height - mybutton.Height));

            //mybutton.BackColor = Color.Red;   //this will generate them red.
            mybutton.MouseClick += new MouseEventHandler(mybutton_MouseClick);
        }

        void mybutton_MouseClick(object sender, MouseEventArgs e)
        {
            //some code here to change the generated button color when they are clicked individually.
            //...
            //...
        }
    }
}

这里：void mybutton_MouseClick(object sender, MouseEventArgs e)发件人实际上是按钮被点击了。

因此只需将 sender 转换为 Button 即可设置其背景颜色。

像这样：

var mybutton = sender as Button;
mybutton.BackColor = Color.Red

委托 button1.MouseClick 事件而不是更改其控件属性

delegate button1.MouseClick event than changes its control properties
