How can one get an absolute or normalized file path in .NET?

Question

How can one with minimal effort (using some already existing facility, if possible) convert paths like c:\\aaa\\bbb\\..\\ccc to c:\\aaa\\ccc?

Answer 1

Canonicalization is one of the main responsibilities of the Uri class in .NET.

var path = @"c:\aaa\bbb\..\ccc";
var canonicalPath = new Uri(path).LocalPath; // c:\aaa\ccc
