SpatialReferenceEnvironment Class (ArcObjects .NET 10.8 SDK)
|
This document is archived and information here might be outdated. Recommended version. |
Creates various spatial reference objects.
SpatialReferenceEnvironment is a singleton object. However, if you are working in a multi-threaded environment, each thread will have its own SpatialReferenceEnvironment. You should not pass information between the threads.
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
