Winform notifyIcon托盘控件的使用

添加notifyIcon控件，选择控件属性页。Icon选择ico格式图标文件，作为托盘化后托盘栏图标；Ballon系列属性与气球状有关；ContextMenuStrip属性设置菜单。

            if (WindowState == FormWindowState.Minimized)
            {
                this.ShowInTaskbar = false;//任务栏
                notifyIcon1.Visible = true;

                this.WindowState = FormWindowState.Normal;//还原大小   可改成最大化
                this.Activate();
                this.ShowInTaskbar = true;//任务栏
                notifyIcon1.Visible = false;
