C＃

Question

我希望如果连接断开，例如1分钟。我的程序正在自动刷新

有可能吗？如果可以，怎么办？

这是我的代码

 public partial class Form1 : Form
   {
       public Form1()
       {
           InitializeComponent();
       }
       private void Form1_Load(object sender, EventArgs e)
       {
           // code die ervoor zorgt dat het programma opstart bij het opstarten van pc
           RegistryKey key = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);
           key.SetValue("youtube", Application.ExecutablePath.ToString());
           //de webbrowser die navigate naar youtube
           webBrowser2 = new WebBrowser();
           webBrowser2.Size = new System.Drawing.Size(78, 446);
           webBrowser2.Dock = System.Windows.Forms.DockStyle.Top;
           this.Controls.Add(webBrowser2);
           Random rand = new Random();
           string[] array = new string[]{ "https://www.youtube.com/watch?v=xQDZogqP4P8&list=PLGonWGLZdZJmvgpBTJDzlMqadJkr6LJ1H&loop=1", "https://www.youtube.com/watch?v=phPL5T168-Q&list=PLGonWGLZdZJmvgpBTJDzlMqadJkr6LJ1H&index=2&loop=1", "https://www.youtube.com/watch?v=gl_BwdQSapI&list=PLGonWGLZdZJmvgpBTJDzlMqadJkr6LJ1H&index=3&loop=1" };
           webBrowser2.Navigate(array[rand.Next(array.Length)]);
       }
   }
}
