Question

If path = “\ProgramFiles\MobileApp\es-gl\a.dll”. I want to get “\ProgramFiles\MobileApp\es-gl” alone. Just want to know the parent directory of the file a.dll. Is there Any inbuilt method in c#? I am using .net Compact Framework

I also needed such a function to find the parent directory of a folder seamlessly. So I created one myself:

        public static string ExtractFolderFromPath(string fileName, string pathSeparator, bool includeSeparatorAtEnd)
        {
            int pos = fileName.LastIndexOf(pathSeparator);
            return fileName.Substring(0,(includeSeparatorAtEnd ? pos+1 : pos));
        }

Just send pathSeparator (“\” for windows and “/” for unix-like paths).
set last parameter true if you want separator included at the end. for ex:
C:\foo\
