Path.Combine absolute with relative path strings

Question

I'm trying to join a Windows path with a relative path using Path.Combine.

However, Path.Combine(@"C:\blah",@"..\bling") returns C:\blah\..\bling instead of C:\bling\.

Does anyone know how to accomplish this without writing my own relative path resolver (which shouldn't be too hard)?

Answer 1

What Works:

string relativePath = "..\\bling.txt"; string baseDirectory = "C:\\blah\\"; string absolutePath = Path.GetFullPath(baseDirectory + relativePath); 

(result: absolutePath="C:\bling.txt")

What doesn't work

string relativePath = "..\\bling.txt"; Uri baseAbsoluteUri = new Uri("C:\\blah\\"); string absolutePath = new Uri(baseAbsoluteUri, relativePath).AbsolutePath; 

(result: absolutePath="C:/blah/bling.txt")

Answer 2

Call Path.GetFullPath on the combined path http://msdn.microsoft.com/en-us/library/system.io.path.getfullpath.aspx

> Path.GetFullPath(Path.Combine(@"C:\blah\",@"..\bling")) C:\bling 

(I agree Path.Combine ought to do this by itself)
