IDaoGetAsProjection Method (ListIDataValueProjector, IGeneralDataProjector, IRetrievalQuery, IDataReader)

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: 5.4.0.0 (5.4.0)

Syntax

Copy

void GetAsProjection(
	List<IDataValueProjector> valueProjectors,
	IGeneralDataProjector projector,
	IRetrievalQuery queryExecuted,
	IDataReader reader
)

Sub GetAsProjection ( 
	valueProjectors As List(Of IDataValueProjector),
	projector As IGeneralDataProjector,
	queryExecuted As IRetrievalQuery,
	reader As IDataReader
)

Parameters

valueProjectors: Type: System.Collections.GenericListIDataValueProjector
The value projectors.
projector: Type: SD.LLBLGen.Pro.ORMSupportClassesIGeneralDataProjector
The projector to use for projecting a plain row onto a new object provided by the projector.
queryExecuted: Type: SD.LLBLGen.Pro.ORMSupportClassesIRetrievalQuery
the query object executed which produced the reader. Pass the executed query object to make sure resultset caching is possible.
reader: Type: System.DataIDataReader
The reader which points to the first row of a resultset

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.
