提问by user2323308
I am new to the batch script programming.Getting error while executing batch file if I give the relative path. I have following folder structure
我是批处理脚本编程的新手。如果我提供相对路径，则在执行批处理文件时会出错。我有以下文件夹结构
Script folder - C:\batch\script\ServiceRegister.bat
Bin path - C:\batch\bin\ERecruitGenerateReportsWindowsService.exe
ServiceRegister.bat Batch file –
ServiceRegister.bat 批处理文件 –
%windir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe %~dp0%~1\bin\ERecruitGenerateReportsWindowsService.exe
When I execute ServiceRegister.bat file I got the error:
当我执行 ServiceRegister.bat 文件时，出现错误：
Exception occurred while initializing the installation:
System.IO.FileNotFoundException: Could not load file or assembly 'file:///C:\batch\script\bin\ERecruitGenerateReportsWindowsService.exe' or one of its dependencies. The system cannot find the file specified.
I am using “%~dp0%~1” to go one level up in the directory still it gets its current path.
我正在使用“%~dp0%~1”在目录中上一级，但它仍然获得当前路径。
%~dp0%~1 - C:\batch\script\
I need the C:\batch\ path. How I can get this path? It works fine If I give the absolute path -
我需要 C:\batch\ 路径。我怎样才能得到这条路？如果我给出绝对路径，它工作正常 -
%windir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe C:\batch\bin\ERecruitGenerateReportsWindowsService.exe

Your attempt to use %~1to go up one level in the directory structure is inventive and totally invalid syntax. The proper syntax is just as simple - use ..\.
您尝试%~1在目录结构中上一级是创造性的且完全无效的语法。正确的语法同样简单易用..\。
A leading \is not required because %~dp0ends with a \.
\不需要前导，因为%~dp0以\.
%windir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe %~dp0..\bin\ERecruitGenerateReportsWindowsService.exe
