有没有办法轻松解析可移植类库中的文件路径？

Question

I'm needing to parse a path into parts from within a portable class library and get things like the filename, extension, just directory name, etc.

All of these methods are fairly easy to access from within System.IO.Path, however, this doesn't seem to exist within portable class libraries. Is there an open source replacement for this or some other API that would give me the same functionality?

Answer 1

You may be able to use or adapt the code for System.IO.Path from Mono: https://github.com/mono/mono/blob/master/mcs/class/corlib/System.IO/Path.cs

EDIT: Also, my PCL Storage library provides some file IO APIs to PCLs, including PortablePath.Combine() .

Answer 2

I would use Uri class

var segments = new Uri("file://c:/dir1/dir2/a.txt").Segments

which is supported by PCL
