IDataAccessAdapter.FetchProjection Method (List<IDataValueProjector>, IGeneralDataProjector, IDataReader, IRetrievalQuery)

Projects the current resultset of the passed in datareader using the value projectors and the projector specified. The reader will be left open

Namespace:  SD.LLBLGen.Pro.ORMSupportClasses
Assembly:  SD.LLBLGen.Pro.ORMSupportClasses (in SD.LLBLGen.Pro.ORMSupportClasses.dll) Version: 5.10.0.0 (5.10.0)
Syntax
Copy
void FetchProjection(
	List<IDataValueProjector> valueProjectors,
	IGeneralDataProjector projector,
	IDataReader reader,
	IRetrievalQuery executedQuery
)

Parameters

valueProjectors
Type: System.Collections.Generic.List<IDataValueProjector>
The value projectors.
projector
Type: SD.LLBLGen.Pro.ORMSupportClasses.IGeneralDataProjector
The projector to use for projecting a plain row onto a new object provided by the projector.
reader
Type: System.Data.IDataReader
The reader which points to the first row of a resultset
executedQuery
Type: SD.LLBLGen.Pro.ORMSupportClasses.IRetrievalQuery
the query object executed which produced the reader. Pass the executed query object to make sure resultset caching is possible.
Remarks
Use this overload together with FetchDataReader if your datareader contains multiple resultsets, so you have fine-grained control over how you want to project which resultset in the datareader. Resultset caching will occur if the passed in executedQuery is setup to cache its resultset.
