我们如何访问传递给 Inno Setup 卸载程序的命令行开关？

Question

Can Inno Setup handle this?

How do we access command line parameters/switches passed to an Inno Setup uninstaller?

I'm trying to make a conditional uninstaller in Innosetup that can conditionally leave behind files. I'd like it to be silent, hence the command line switches.

Answer 1

You can use ParamStr and ParamCount functions.

In case your command-line switch have a value, using {param:ParamName} pseudo-constant can be more convenient.
