Question

嗨，这是我第一篇请跟我说的帖子。 ;）

我有一个小类，在事件发生时生成按钮。我似乎无法实现的是将代码添加到委托mybutton_MouseClick 这会改变单个生成按钮的颜色。

所以我正在寻找一些可以做的代码： 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.
            //...
            //...
        }
    }
}

此处：void mybutton_MouseClick(object sender, MouseEventArgs e)发件人实际上是点击按钮。

所以只需将sender投射到Button，您就可以设置背景颜色了。

像这样：

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

委托button1.MouseClick事件比更改其控件属性
