为什么按钮会闪烁？

Question

当我进入主按钮时，我有2个按钮（从现在开始的自定义按钮）添加到按钮的控件（从现在开始的主按钮）我希望自定义按钮出现ImageBackground，这是例外。现在，当我用鼠标进入自定义按钮时，我希望2 ImageBackground再次出现，当发生这种情况时，我希望主按钮保持与我第一次使用鼠标输入时相同的颜色我想要它，但按钮是闪烁的，有时当我输入另一个主按钮的自定义按钮时，前一个按钮仍处于mouseEnter状态。这是为什么？我是否需要使用async / await或类似的东西？

我想也许是因为它必须在它发生时进行编译，这需要一点时间，这就是为什么它会闪烁，这就是我认为我需要使用async / await的原因，但这对我来说真的很新，所以我不喜欢我知道如何使用它。

public class MyButton : Button
    {
        public MyButton()
        {
            SetStyle(ControlStyles.StandardClick | ControlStyles.StandardDoubleClick | ControlStyles.UserMouse, true);

            Margin = new Padding(0);
            TextAlign = ContentAlignment.TopCenter;
            ImageAlign = ContentAlignment.TopLeft;
            TextImageRelation = TextImageRelation.ImageBeforeText;
            Font = new Font("Century Gothic", 11f, FontStyle.Bold);
            Size = new Size(200, 75);
            FlatStyle = FlatStyle.Flat;
            BackColor = Color.FromArgb(0, 255, 255, 255);
            FlatAppearance.MouseOverBackColor = ColorTranslator.Fromhtml("#64A4B3B6");
            FlatAppearance.BorderSize = 2;
            FlatAppearance.BorderColor = Color.FromArgb(0, 255, 255, 255);

            Button[] custom = CustomButtons();
            for (int i = 0; i < 2; i++)
            {
                Controls.Add(custom[i]);
                Controls[i].MouseHover += CustomOnMouseEnter;
            }

            MouseEnter += OnMouseEnter;
            MouseLeave += OnMouseLeave;
        }

        private Button[] CustomButtons()
        {

            Button delete = new Button();
            delete.Name = "delete";
            delete.Location = new Point(this.Size.Width - 22, 2);
            delete.Size = new Size(20, 20);
            delete.FlatStyle = FlatStyle.Flat;
            delete.BackColor = Color.Transparent;
            delete.FlatAppearance.MouseOverBackColor = ColorTranslator.FromHtml("#64A4B3B6");
            delete.FlatAppearance.BorderSize = 0;

            Button customize = new Button();
            customize.Name = "customize";
            customize.Location = new Point(delete.Left - 20, delete.Top);
            customize.Size = new Size(20, 20);
            customize.FlatStyle = FlatStyle.Flat;
            customize.BackColor = Color.Transparent;
            customize.FlatAppearance.MouseOverBackColor = ColorTranslator.FromHtml("#64A4B3B6");
            customize.FlatAppearance.BorderSize = 0;

            Button[] buttons = { delete, customize };
            return buttons;
        }

        private void OnMouseLeave(object sender, EventArgs e)
        {
            if (Controls.Count != 0)
            {
                Controls[0].BackgroundImage = null;
                Controls[1].BackgroundImage = null;
            }

            if (BackColor != ColorTranslator.FromHtml("#64389eed"))
            {
                BackColor = Color.FromArgb(0, 255, 255, 255);
            }
        }

        private void OnMouseEnter(object sender, EventArgs e)
        {
            if (Controls.Count != 0)
            {
                Controls[0].BackgroundImage = Resources.cross;
                Controls[1].BackgroundImage = Resources.settings;
            }
        }

        private void CustomOnMouseEnter(object sender, EventArgs e)
        {
            this.BackColor = ColorTranslator.FromHtml("#64A4B3B6");
            Controls[0].BackgroundImage = Resources.cross;
            Controls[1].BackgroundImage = Resources.settings;
        }
    }

这是代码的输出，你可以看到我输入自定义按钮时的闪烁和前一个按钮处于MouseEnter状态的方式，即使我离开它！

非常感谢每一位帮助！
