ado.net Closing Connection when using “using” statement

Question

I am doing my database access methods to SQL Server like this

  using (SqlConnection con = new SqlConnection(//connection string)
  {
    using (SqlCommand c         


        

Answer 1

I think "using" was not required for SqlCommand. "Using" for SqlConnection would have done the job for you alone. In fact you connection is submitted to Connection pool.
