如何在批处理文件中使用 if - else 结构? [英] How to use if - else structure in a batch file?

问题描述

我有一个关于批处理文件中的 if - else 结构的问题.每个命令都单独运行，但我无法安全地使用if - else"块，因此我的程序的这些部分不起作用.我怎样才能让这些部分运行?谢谢.

I have a question about if - else structure in a batch file. Each command runs individually, but I couldn't use "if - else" blocks safely so these parts of my programme doesn't work. How can I do make these parts run? Thank you.

IF %F%==1 IF %C%==1 (
    ::copying the file c to d
    copy "%sourceFile%" "%destinationFile%"
    )
ELSE IF %F%==1 IF %C%==0 (
    ::moving the file c to d
    move "%sourceFile%" "%destinationFile%"
    )

ELSE IF %F%==0 IF %C%==1 (
    ::copying a directory c from d, /s:  boş olanlar hariç, /e:boş olanlar dahil
    xcopy "%sourceCopyDirectory%" "%destinationCopyDirectory%" /s/e
    )
ELSE IF %F%==0 IF %C%==0 (
    ::moving a directory
    xcopy /E "%sourceMoveDirectory%" "%destinationMoveDirectory%"
    rd /s /q "%sourceMoveDirectory%"
    )

推荐答案

您的语法不正确.您不能使用 ELSE IF.无论如何，您似乎并不真正需要它.只需使用多个 IF 语句:

Your syntax is incorrect. You can't use ELSE IF. It appears that you don't really need it anyway. Simply use multiple IF statements:

IF %F%==1 IF %C%==1 (
    ::copying the file c to d
    copy "%sourceFile%" "%destinationFile%"
    )

IF %F%==1 IF %C%==0 (
    ::moving the file c to d
    move "%sourceFile%" "%destinationFile%"
    )

IF %F%==0 IF %C%==1 (
    ::copying a directory c from d, /s:  boş olanlar hariç, /e:boş olanlar dahil
    xcopy "%sourceCopyDirectory%" "%destinationCopyDirectory%" /s/e
    )

IF %F%==0 IF %C%==0 (
    ::moving a directory
    xcopy /E "%sourceMoveDirectory%" "%destinationMoveDirectory%"
    rd /s /q "%sourceMoveDirectory%"
    )
