Access CurrentUser Registry Key for Impersonated User - Compatibility with .NET 3.5

Question

I\'ve recently written an application that impersonate user account, get a handle to CURRENT_USER registry key (using PInvoke \"LoadUserProfile\" to retrieve ProfileInfo.hPr

Answer 1

Wrote an Impersonation class I posted here to answer the same kind of question: Impersonate admin account to edit registry key not working (C#)

To write to the key, you just do:

string userName = "domain\user";
string password = "whatever";
string KEY_STR = "SomeSubKey\\ASubKeyToThat";

WindowsImpersonationContext adminContext = Impersonation.getWic(userName, password);
if (adminContext != null)
{
    try
    {
       RegistryKey key = Registry.CurrentUser.OpenSubKey(KEY_STR, true);
       key.SetValue("State", 0x60001);
    }
    catch (Exception ex)
    {
        Console.Out.WriteLine("\nUnable to set registry value:\n\t" + ex.Message);
        Impersonation.endImpersonation();
        adminContext.Undo();
    }
    finally
    {
        Impersonation.endImpersonation();
        // The above line does this --            
        //if (tokenHandle != IntPtr.Zero) CloseHandle(tokenHandle);
        adminContext.Undo();
    }
}

No handles or other fancy functions, other than to get the WindowsImpersonationContext needed. Didn't repost that part because it looks like you already know how to get the WIC.
