asp.net - Can you use 2 'using' statements for both sqlconnection and sqldatareader?

Question

Can you use 2 'using' statements like:

using (SqlConnection ..)
{
    using(SqlDataReader reader = new SqlDataReader())
    {

     }

}

I'm trying to do this put getting an error on the constructor of the SqlDataReader

Answer 1

SqlDataReader has no constructor. You are returned a datareader by calling the ExecuteReader method of a SqlCommand object.

e.g.

using (SqlConnection ..) 
{ 
    SqlCommand cmd = new SqlCommand(...);
    using(SqlDataReader reader = cmd.ExecuteReader())) 
    { 

    } 

}
