Question

0.00/5 (No votes)

See more:

In windows 10 some CLSID keys newly added, like quick access folder, Frequent folder, etc..

in windows 10 and previous edition of windows there are CLSID keys like document, downloads...

Now, My problem is, I have below piece of code that are use to get the folder path. its working fine with old CLSID key but when I want to get the newly added(quick access folder, Frequent folder) folder path its giving exception like "The System can not find the file specified".

What I have tried:

Native method

C#

[DllImport("shell32.dll", CharSet = CharSet.Auto, SetLastError = true)] 
        public static extern int SHGetKnownFolderPath( 
            [MarshalAs(UnmanagedType.LPStruct)] Guid rfid, 
            uint dwFlags, 
            IntPtr hToken, 
            out IntPtr pszPath);

public static string SHGetKnownFolderPath(Guid rfid)
        {
            IntPtr pPath = IntPtr.Zero;
            string path = null;
            try
            {

                int hr = NativeMethods.SHGetKnownFolderPath(rfid, 0, IntPtr.Zero, out pPath);
                if (hr != 0)
                {
                    throw Marshal.GetExceptionForHR(hr);
                }
                path = Marshal.PtrToStringUni(pPath);
            }
            finally
            {
                if (pPath != IntPtr.Zero)
                {
                    Marshal.FreeCoTaskMem(pPath);
                    pPath = IntPtr.Zero;
                }
            }
            return path;
        }



Guid LocalAppDataGuid = new Guid("679f85cb-0220-4080-b29b-5540cc05aab6");
m_szFolderPath = SHGetKnownFolderPath(LocalAppDataGuid);

its working for document, download but but its not working for quick access windows 10.

679f85cb-0220-4080-b29b-5540cc05aab6 - quick access.

Is there any other approach to get the this path?.

Thanks in advance.

What is wrong with Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)?
