Get OneDrive path in Windows

I have a C# WPF application and I am trying to find a way to get the path to the root OneDrive directory in Windows. How can I do this programmatically? I have searched online, but I couldn't find anything. I wish I could supply some code but I have no clue; I mean, I have checked system environment variables and I couldn't find anything on my machine, thinking that could be a valid solution, but it didn't turn up anything.

Answer

On my Windows 8.1 computer, the registry key that holds this information is: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\SkyDrive\UserFolder

I'd try using the Registry.GetValue() method:

        const string userRoot = "HKEY_CURRENT_USER";
        const string subkey = @"Software\Microsoft\Windows\CurrentVersion\SkyDrive";
        const string keyName = userRoot + "\\" + subkey;

        string oneDrivePath = (string)Registry.GetValue(keyName,
        "UserFolder",
        "Return this default if NoSuchName does not exist.");
        Console.WriteLine("\r\n OneDrivePath : {0}", oneDrivePath);

I also found the path under:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\SyncRootManager\SkyDrive\UserSyncRoots\S-1-5-21-2696997101-1021499815-432504798-1004

HKEY_USERS\S-1-5-21-2696997101-1021499815-432504798-1004\Software\Microsoft\Windows\CurrentVersion\SkyDrive\UserFolder
