MacOS X 10.11.3 中的 F# 目录和路径

Question

Hi i'm a newbie in MacOS X (10.11.3) and have used so far F# in VS2015 on Win8.1

I have some questions:

1- in F# Interactive, if i wanna say, have the list of files of the directory ~/Documents

Directory.GetFiles(@"~/Documents") doesn't work. What is the right syntax ?

if i want to do a #r xxx.dll , how do i specify rightly the path

2- same question in a source file (.fs or .fsx)

thanks

EDIT for example I get the following in F# interactive

let CD = "/Documents";;

val CD : string = "/Documents"

Directory.GetFiles(CD);;

System.IO.DirectoryNotFoundException: Directory '/Documents' not found.

I assume maybe you're using Mono/Xamarin? I don't have experience with MacOS but .NET should be available. You can access your home directory with: System.Environment.GetEnvironmentVariable("USERPROFILE") There are also other variables accessing special folders but I'm not sure how windows specific is that. For your second question you can use #I @"path/to/dll" to specify the folder where the dll is and then add the dll name with #r @"file.dll" . This works in both fs and fsx files. You might want put this in between #if INTERACTIVE #endif block. And for compiled stuff you can add the reference to the DLL in your IDE directly.
