Why sql Data Reader object not created

Answer Posted / boopathiraj

we can't create an object for data reader because the
datareader is used to retrive the data's from the database
and it uses only some small amount of databases unlike
dataset.We can just create the variable for the datareader
is possible.And then THE CONSTRUCTORS WAS NOT DEFINED BY
SYSTEM.DATA.SQLCLIENT.SQLDATAREADER.(i.e)when you typed
(System.data.sqlclient)upto this is possible if you use
(System.data.sqlclient)(.sqldatareader)--->Not possible and
it is applicable when you use microsoft visual studio.net
