Can I turn off impersonation just in a couple instances

Question

I have an app that has impersonation used throughout. But when a user is logged in as an admin, a few operation require them to write to the server itself. Now if these users do not have rights on the actual server (some don't) it will not let them write.

What I want to do is turn off impersonation for just a couple commands.

Is there a way to do something like this?

using(HostingEnvironment.Impersonate.Off())
  //I know this isn't a command, but you get the idea?

Thank you.

Make sure the Application Pool do have the proper rights that you need.

Then, when you want to revert to the application pool identity... run the following:

private WindowsImpersonationContext context = null;
public void RevertToAppPool()
{
    try
    {
        if (!WindowsIdentity.GetCurrent().IsSystem)
        {
            context = WindowsIdentity.Impersonate(System.IntPtr.Zero);
        }
    }
    catch { }
}
public void UndoImpersonation()
{
    try
    {
        if (context != null)
        {
            context.Undo();
        }
    }
    catch { }
}
