✅ System.NullReferenceException: 'Object reference not set to an instance of an object.'
I get error when I map one object to other. I checked
sdc object using debug and all properties aren't null. What can I do to solve the problem?
private Data.Entities.Station MapStationFeatureToStation(StationDetailsContract sdc)
{
return new Data.Entities.Station
{
Id = sdc.Id.ToString(),
TmsNumber = sdc.Properties.TmsNumber,
Name = sdc.Properties.Name,
Names =
{
Fi = sdc.Properties.Names?.Fi ?? string.Empty,
Sv = sdc.Properties.Names?.Sv ?? sdc.Properties.Names?.Fi ?? string.Empty,
En = sdc.Properties.Names?.En ?? sdc.Properties.Names?.Fi ?? string.Empty
},

{
Longitude = sdc.Geometry.Coordinates[0],

},
