Question

To combine two parts of a file path, you can do

System.IO.Path.Combine (path1, path2);

However, you can’t do

System.IO.Path.Combine (path1, path2, path3);

Is there a simple way to do this?

Answer 1

As others have said, in .NET 3.5 and earlier versions there hasn’t been a way to do this neatly – you either have to write your own Combine method or call Path.Combine multiple times.

But rejoice – for in .NET 4.0, there is this overload:

public static string Combine(
    params string[] paths
)

There are also overloads taking 3 or 4 strings, presumably so that it doesn’t need to create an array unnecessarily for common cases.

Hopefully Mono will port those overloads soon – I’m sure they’d be easy to implement and much appreciated.
