c# - 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:lah",@"..ling") returns C:lah..ling instead of C:ling.

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:ling.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")
