Process.Start（“ echo”，“％cd％”）引发W32Exception文件未找到 [英] Process.Start("echo", "%cd%") throws W32Exception File Not Found

问题描述

当我尝试执行 Process.Start（ echo，％cd％）时，它会引发 System.ComponentModel.Win32Exception：系统找不到指定的文件。
当我在 cmd 中手动执行此操作时，它会按应有的方式工作。我从来不知道有什么区别……

When I try to do Process.Start("echo", "%cd%") it raises a System.ComponentModel.Win32Exception: The system cannot find the file specified. When I do this manually in cmd it just works like it should. I never knew that there's a difference...

此外，当我执行 File.Exists（logfile.txt）（绝对路径）绝对应该存在的文件，它返回false。这是上面 echo 的原因：调试...

Also, when I do File.Exists(logfile.txt) (w/o path) of a file that should definitely be there, it returns false. This is btw the reason for the echo above: debugging...

此错误不会在我的计算机上发生开发机器，仅在我正在测试的另一台机器上。

This error doesn't occur on my developement machine, only on another one where I am testing on.

Path变量看起来很正常。两者都是WinXP。两者都在运行.NET 3.5

The Path variable looks normal. Both are WinXP. Both are running .NET 3.5

推荐答案

尝试 Process.Start（ cmd.exe， / c echo％CD％）

只要echo不是可执行文件而是内部命令。

as far as echo is not an executable but a command inside.
