DataReader object
Explain DataReader object?
Expert
DataReader object helps in accessing the data from the database in a read-only, forward-only mode. Base class for all DataReader objects is the DbDataReader class. The DataReader object is returned as a result of calling the ExecuteReader() method of the Command object. The DataReader object allows faster retrieval of the data from the databases and develops the performance of .NET applications by giving the rapid data access speed. Though, it is less preferred as compared to theDataAdapter object since the DataReader object requires an Open connection till it completes reading all the rows of specified table.
An Open connection required to read the data from large tables consumes many resources of the system. When multiple client applications at the same time access a database by using DataReader object, performance of the data retrieval and other related processes gets significantly reduced. In this case, database might refuses the connections to other .NET applications until other clients frees the resources.
