异常后继续循环执行

Question

I want the for loop to continue execution if an exception occurs (99 out of 100, wiil be conection problem to portal), meaning move to connecting to next portal.

I thought using I finally compined with a goto but I dislike using goto .

 for (int i = 0; i < Portals.Count; i++)
{
    try
       {
        if (!Portals[i].IsConnected)
          {
             Portals[i].Connect();
             ///..Permorm variours actioms...
          }
        }
    catch 
        {
         Window7 win = new Window7();
         win.label1.Content = "Connect to Portal " + (i + 1).ToString() + " Failed..";
         win.ShowDialog();
         return;
        }

If you wish to continue with the code placed after the try/catch use this :
(simply remove the return; statement)

for (int i = 0; i < Portals.Count; i++)
{
    try
    {
        if (!Portal[i].IsConnected)
        {
            Portal[i].Connect();
            ///..Permorm variours actioms...
        }
    }
    catch 
    {
        Window7 win = new Window7();
        win.label1.Content = "Connect to Portal " + (i + 1).ToString() + " Failed..";
        win.ShowDialog();
    }
    // TODO - Some more code here
}

If you wish to stop that iteration if an Exception occurs, simply replace your return by a continue :

for (int i = 0; i < Portals.Count; i++)
{
    try
    {
        if (!Portal[i].IsConnected)
        {
            Portal[i].Connect();
            ///..Permorm variours actioms...
        }
    }
    catch 
    {
        Window7 win = new Window7();
        win.label1.Content = "Connect to Portal " + (i + 1).ToString() + " Failed..";
        win.ShowDialog();
        continue;
    }
    // TODO - Some more code here
}
