BeginWaitCursor and EndWaitCursor are used to display an hourglass
cursor. lock is used to synchronize access to a resource from multiple
accesses across threads. They are not related.

What are you trying to do?

my c++ code;
----------------
BeginWaitCursor();
if (test1)
//do stuff
else if (test2)
//then do this stuff
EndWaitCursor();

but if all i'm doing is showing an hourglass i can simply use the cursor
class?

Try:

Cursor.Current = Cursors.WaitCursor;

try
{
// Put your processing here.
if (test1)...
}
finally
{
Cursor.Current = Cursors.Default;
}

lock will serialise access to the contained code over multiple threads of
execution; probably not what you require in this instance.

The finally block above ensures that if any exceptions are thrown that the
cursor is restored to the default.

BeginWaitCursor();
if (test1)
//do stuff
else if (test2)
//then do this stuff
