Remarks

The valid lock flags for this method are:

LockFlags.Discard

LockFlags.NoDirtyUpdate

LockFlags.NoSystemLock

LockFlags.ReadOnly

For performance reasons, dirty regions are recorded only for level zero of a texture. Dirty regions are automatically recorded when Volume.LockBox is called without LockFlags.NoDirtyUpdate or LockFlags.ReadOnly. For more information, see Device.UpdateTexture.

Exceptions
