This line of code is the spatial reference that sets the PPoint, which is the projected coordinate of the point to be converted. If the projection coordinates are not known, the conversion will be reported as abnormal.
2414 is the enum value for the projection, if you want to query the wkid of the coordinate system, click Geographic coordinate system: www.cnblogs.com/hyqing/p/3660611.html and projected coordinate system www.cnblogs.com/hyqing/p/3660662.html
