The C# using statement, SQL, and SqlConnection

Question

Is this possible using a using statement C# SQL?

private static void CreateCommand(string queryString,
    string connectionString)
{
    using (SqlConnectio         


        

Answer 1

It's possible to do so in C# (I also see that code is exactly shown in MSDN http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlcommand.executenonquery.aspx). However, if you need to be defensive and for example log potential exceptions which would help troubleshooting in a production environment, you can take this approach:

private static void CreateCommand(string queryString,
string connectionString)
{
    using (SqlConnection connection = new SqlConnection(
           connectionString))
    {
        try
        {
            SqlCommand command = new SqlCommand(queryString, connection);
            command.Connection.Open();
            command.ExecuteNonQuery();
        }
        catch (InvalidOperationException)
        {
            //log and/or rethrow or ignore
        }
        catch (SqlException)
        {
            //log and/or rethrow or ignore
        }
        catch (ArgumentException)
        {
            //log and/or rethrow or ignore
        }
    }
}
