無效的轉義序列（有效的轉義序列是\ b \ t \ n \ f \ r \「\'\\）

好的，所以即時編寫程序，從我的USB傳輸文件到計算機（所以我可以設置的東西快速爲週一即將做的事情），並試圖讓它在桌面上做一個快捷方式，所以你不必進入文件傳輸的源文件夾，所以你可以啓動程序，以防止你退出它。我的代碼，標題是錯誤即時得到。無效的轉義序列（有效的轉義序列是 b t n f r 「'\）

你似乎在Windows路徑中使用UNIX分隔符（'/'），您是否嘗試過使用'File.separator'來代替？ – 2012-03-30 19:14:00

錯誤是哪一行？ – 2012-03-30 19:15:02

String line = "-shortcut -t c:/ocuments and Settings/%username%/Desktop/TS3/ts3client_win32.exe" "-n Teamspeak 3.lnk";

此行似乎格式錯誤，你有兩個字符串，而不+之間。
