I am trying to understand why this works ...

using (Process ProcRegEdit = Process .Start("REGEDIT.EXE", "/s
C:\\Ajay\\VS2005\\C#\\REGISTRY\\ajay.reg"))
  {

    ProcRegEdit.WaitForExit(); // Wait indefinitely
    if (ProcRegEdit.HasExited)
        {
         ProcRegEdit.Close();
        }

... but this does not.

           using (Process ProcRegEdit = new Process())
           {
               ProcRegEdit.Start("REGEDIT.EXE", "/s
C:\\Ajay\\VS2005\\C#\\REGISTRY\\ajay.reg");
               ProcRegEdit.WaitForExit(); // Wait indefinitely
                 if (ProcRegEdit.HasExited)
               {
                   ProcRegEdit.Close();
               }

           }
/* NOTES
This line ...

ProcRegEdit.Start("REGEDIT.EXE", "/s
C:\\Ajay\\VS2005\\C#\\REGISTRY\\ajay.reg");

... generates a build error with the following message

Static member 'member' cannot be accessed with an instance reference;
qualify it with a type name instead

Thanks.
