    >>The IDataReader is like the IDbConnection it lets you deal with most RDBMS
    >>IDataReader is refers to an interface.This means you can use any data reader you want basically. The method will accept your datareader because the datareader implements the IDataReader interface.
    >>The advantage of doing this is that the method is not specific to a specific type of data reader. You could also roll your own class that implements this interface.

    >>The SqlDataReader is a class which implements IDataReader. This means that anywhere an IDataReader may be used you can use SqlDataReader.

    It is an interface.It Provides a means of reading one or more forward-only streams of result sets obtained by executing a command at a data source, and is implemented by .NET Framework data providers that access relational databases.

    Difference between sqldatareader and idatareader:

    The IDataReader is an Interface for all Datareader classes.
    The SqlDataReader class inherits from the DbDataClass and adds some SQL-server specific code.
