Hi,

My requirement is to have spaital reference with User Defined Coordinate System ?? I am from India , and the rquirement is to add projection system of Indian Grid System (IGRS) . I went through the documentation

Spatial references—ArcGIS Runtime SDK for .NET | ArcGIS for Developers , but I am unable to understand how to achieve it, Can anyone help me with some example or some kind of help ?? Thanks in advance

If custom coordinate systems are supported at all, you would probably have to use it via a WKT (well-known text) string. Can you post the information for it:

geographic coordinate system / datum (+ ellipsoid)

map projection

parameters

linear units

I have a .prj (projection file) , which contains well known text. Will it be sufficient?

try

string wkt = File.ReadAllText(PATH_TO_PRJ_FILE);

SpatialReference sr = SpatialReference.Create(wkt);
