Closing SqlConnection and SqlCommand c#

Question

In my DAL I write queries like this:

using(SQLConnection conn = \"connection string here\")
{
    SQLCommand cmd = new (\"sql query\", conn);
    // execute          


        

Answer 1

It won't handle the SqlCommand, but the SqlCommand will eventually be handled by the garbage collector. I tend to do the following:

using (SqlConn conn ... )
using (SqlComm comm ... )
{
    conn.Open();
}

Stacking the using statements here will handle both.
