How to properly close ODP.net connection : dispose() or close()?

Question

this is my powershell code :

[void][System.Reflection.Assembly]::LoadFile(\"C:\\DLL\\Oracle.ManagedDataAccess.dll\")
$OracleConnexion = New-Object Oracle.Ma         


        

Answer 1

More standard implementation for resource which implement IDisposable is by wrapping it by using:

using (OracleConnection connection = new OracleConnection(connectionString)){
    using (OracleCommand command = new OracleCommand(sql, connection))
        using (OracleDataReader reader = cmd.ExecuteReader())
        {
        }
    connection.Close(); //optional
}

It is equivalent to implementing .Dispose after the execution block. Internally, Dispose will also handle the closing. Nevertheless, you could also call the .Close() after the command block.

A sample in the oracle documentation which uses Oracle.DataAccess encourages the use of Dispose too.
