C# Canonical file names

Question

How to get canonical file name by non-canonical one.

E.g. I want to call function which converts "C:\Program files\..\Windows\aaa.txt" to "C:\Windows\aaa.txt"

I am looking for something like Java File.getCanonicalPath()

is [this](http://msdn.microsoft.com/en-us/library/system.io.path.getfullpath.aspx) what you looking for? — Renatas M., Nov 11 '11 at 10:02

You can use the Path.GetFullPath method for this.

Example:

Console.WriteLine(Path.GetFullPath(@"C:\Program files\..\Windows\aaa.txt"));

Output:

C:\Windows\aaa.txt

It's good but be warned it's not a full replacement of CanonicalPath - Java's CanonicalPath will do things like normalize the capitalization of drive letters inside the path, and that is not happening in .NET's GetFullPath... In .NET the `Path` class has a GetFullPath method and there is similar functionality in the FullName property of `FileInfo`. – Mishax Aug 22 '13 at 10:49

System.IO.Path.GetFullPath("C:/Program files/../Windows/aaa.txt")

will return

"C:\\Windows\\aaa.txt"

Here is my suggestion:

string path = Path.GetFullPath(@"C:\Program files\..\Windows\aaa.txt");
