本来用 Python 实现了一个类似功能，就想着用 Visual Studio C# 能不能实现个，纯属写着好玩。但一直提示这个错误，下断点，我看了值也没问题。故而求助下 V 友

初学者，写得不好还请见谅

1. Visual Studio Code != Visual Studio
2. 既然知道异常，为何不把异常贴出来？ PowerShell 路径问题。代码的路径写着是 C:\WINDOWS\system32\powershell.exe |

+1 路径问题吧，实际 powershell 可不在这个路径，我用下面这个就能调用到
ProcessStartInfo startInfo = new ProcessStartInfo { FileName = "powershell", Arguments = $"echo hello", RedirectStandardOutput = true, RedirectStandardError = true, UseShellExecute = false, CreateNoWindow = true }; |
