2414 );

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

int ) esrisrgeocstype.esrisrgeocs_beijing1954));


Converts the projected coordinates of the point to latitude and longitude.

Latitude to projection:

Private int int Prjtype) {    new  spatialreferenceenvironmentclass ();     = Psrf.creategeographiccoordinatesystem (gcstype);    Ppoint.project (Psrf.createprojectedcoordinatesystem (Prjtype));     return

If it appears that the interop type hint cannot be embedded, right-click on the introduced AE Library and change the embed interop type in its properties to False
