嘗試Catch Block不會阻止異常

Question

我正在構建一個程序，它將移動一堆文件。

            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遇到異常。 有時文件不存在。

我怎樣才能做到這一點，如果它失敗了它只輸出失敗並繼續前進？

刪除throw; 如果您不希望您的應用程序中斷，您也可以處理異常
