Working with paths

Concatenating paths shouldn't be done just using string concatenation, because the directory separator may differ on various platforms. This snippet shows a simple custom operator for working with paths.

/// Custom operator for combining paths
let (+/) path1 path2 = Path.Combine(path1, path2)

// Root path obtained from some function
let root = (...)
// Create path for a specific file
let file = root +/ "Subdirectory" +/ "Test.fsx"
namespace System
namespace System.IO
val path1 : string
val path2 : string
type Path =
  static val DirectorySeparatorChar : char
  static val AltDirectorySeparatorChar : char
  static val VolumeSeparatorChar : char
  static val InvalidPathChars : char[]
  static val PathSeparator : char
  static member ChangeExtension : path:string * extension:string -> string
  static member Combine : [<ParamArray>] paths:string[] -> string + 3 overloads
