public bool Remove[Type]( string issuer, string code )
Above, [Type]is a placeholder for the class name of the desired object.
The DataSource has a 'Remove' method for each type of object that can reside in the data source. The 'Remove' method will delete an object from the data source that matches the identifiers passed as argument. For example, in order to remove an AngularUnit from the data source, one would use the RemoveAngularUnit method, and to remove a PrimeMeridian from the data source, one would use the RemovePrimeMeridian method.
There are two parameters for the 'Remove' methods. The first argument is the issuer for the object, and the second is the code to identify the object in the data source.
If the specified identifier does not exist in the DataSource, a GeoCalcException will be thrown with ErrorCode specifying IdentifierNotFound. If the Editable property is false, then a GeoCalcException will be thrown with ErrorCode specifying FileReadOnly.
