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

No, the using statement will not take care of the command.

You should wrap the commands with using statements as well, since this will properly call Dispose on them:

using(SQLConnection conn = 'connection string here')
{
    using(SQLCommand cmd = new ('sql query', conn))
    {
        //execute it blah blah
    }
}
