如何阅读命令行争论 [英] How to read command line arguements

问题描述

我在某处找到了此代码(我丢失了URL)，我想使其同时适用于fsi.exe和fsc.exe.对于fsi.exe，它似乎工作正常.我也该如何为fsc.exe工作?

I found this code somewhere (I lost the URL) and I would like to make it work for both fsi.exe and fsc.exe. It seems to work OK for fsi.exe. How can I make to work for fsc.exe too?

let argv = 
#if INTERACTIVE
  fsi.CommandLineArgs
#else
  Sys.argv
#endif

当我尝试编译fsc.exe时，我不断收到错误消息.这个神奇的数组Sys.argv在哪里定义?

I keep getting errors from fsc.exe when I try to compile it. Where is this magical array Sys.argv defined?

还:fsi是否有一个命令行参数，它将使它执行扩展名为.fs的文件，还是我必须将其重命名为扩展名为.fsx的文件?

Also: is there a command line argument for fsi that will make it execute a file with the extension of .fs or do I have to rename it to have an extension of .fsx?

以下代码对我有用读取fsc.exe的命令行参数.

The following code worked for me to read the command lines argument for fsc.exe.

let ary = System.Environment.GetCommandLineArgs()
Array.iter (printf "%s ") ary
