create With Wkid Or Null
Creates a spatial reference based on WKID for the horizontal coordinate system and vertical coordinate system. The method creates a spatial reference that has both horizontal and vertical coordinate systems. When the vertical WKID is null or less than or equal to 0, this is equivalent to calling SpatialReference.SpatialReference, and the spatial reference will not have a vertical coordinate system associated with it. If an error occurs due to an invalid wkid or verticalWkid, this function will return null.
