Creates a spatial reference from a PRJ file.
[Visual Basic .NET] Public Function CreateESRISpatialReferenceFromPRJFile ( _ ByVal prjFile As String _ ) As ISpatialReference
[C#] public ISpatialReference CreateESRISpatialReferenceFromPRJFile ( string prjFile );
[C++]
HRESULT CreateESRISpatialReferenceFromPRJFile(
BSTR prjFile
);
[C++] Parameters prjFile
prjFile is a parameter of type BSTR
Both old style (workstation) and new style (ArcGIS for Desktop Basic) prj files can be used with this method to create spatial reference system objects.
