Path.Combine and the dot notation [duplicate]
Use Path.GetFullPath string path = Path.Combine(@”c:\alpha\beta”, @”..\gamma”); Console.WriteLine(Path.GetFullPath(path)); or the DirectoryInfo class: string path = Path.Combine(@”c:\alpha\beta”, @”..\gamma”); DirectoryInfo info = new DirectoryInfo(path); Console.WriteLine(info.FullName); Both will output: c:\alpha\gamma
