Today, during the test, I don’t know who added this sentence after the sentence

process.StartInfo = processStartInfo;

:

process.StartInfo.UseShellExecute = false;

I didn’t pay attention at first, and then kept reporting the following error:

The specified executable is not a validapplication for this OS platform.

Explanation:

ProcessStartInfo.UseShellExecute attribute: Gets or sets a value that indicates whether to use the operation The system shell starts the process.

Attribute Value:
To use the shell program when starting the process, it is TRUE; otherwise, the process of creating processes from executable files directly. Defaults to true. Setting the property to false redirects input, output, and error streams. Otherwise it won't work.
When you use the operating system shell to start a process, you can use the Process component to start any document (which can be any registered file type associated with an executable file with a default open action) and perform operations on the file (such as printing) . If UseShellExecute is false, the executable can only be launched using the Process component.
