嘗試捕捉塊不阻止異常

我正在構建一個程序，將移動一堆文件。嘗試捕捉塊不阻止異常

  if (line.Contains("INSERT INTO BACKLOGITEM_ATTACHMENT VALUES")) 
      { 
       string AttachementID = line.Split(',', ')')[1]; 
       string FileName = AttachementsDictionary[AttachementID]; 
       string BacklogScrumID = BacklogLookupDictionary[AttachementID]; 
       BacklogItem Story = BacklogItemDictionary[BacklogScrumID]; 
       Product Product = ProductDictionary[Story.ProductScrumId]; 

       string FileToCopy = "\\\\dxScrum01v\\ScrumWorksPro\\scrumworks\\data\\attachments\\product" + Story.ProductScrumId + "\\attachement" + AttachementID; 
       string FileToSave = "C:\\ScrumWorksAttachementExport\\" + Product.ProductName + "\\" + Product.StoryPrefix + "-" + Story.StoryTitle + "\\" + FileName; 

       //Console.WriteLine(FileToCopy + " >>> " + FileToSave); 
       try 
       { 
        File.Copy(@FileToCopy, @FileToSave); 
       } 
       catch (Exception) 
       { 
        Console.WriteLine("Failed: " + FileToSave); 
        throw; 
       } 

      }

問題是我在運行程序時收到異常。有時文件不存在。

我該如何做到這一點，如果它失敗了，它只是輸出失敗，並繼續前進？
