dbCommand.Close()也会关闭连接吗？

Question

我有以下ado.net代码,如果我已经使用使用来换我的DBCommand,我必须明确地关闭连接下？

谢谢,

       public static void ExecuteSQL(int Id)
        {
            Database db;
            const string sqlCommand = "Stored Procedure Name";
            try
            {
                db = DatabaseFactory.CreateDatabase();
                using (DbCommand dbCommand = db.GetStoredProcCommand(sqlCommand))
                {
                    db.AddInParameter(dbCommand, "p_Id", DbType.Int32, Id);
                    db.ExecuteNonQuery(dbCommand);
**//do I have to close connection explicitely here??**
                    if (dbCommand.Connection.State != ConnectionState.Closed)
                    {
                        dbCommand.Connection.Close();
                    }
                    dbCommand.Connection.Dispose();
                }
            }
            catch (Exception ex)
            {
                Logger.Log.Error(ex.StackTrace, ex);
                throw;
            }
        }

是的,如果您在using块中包含的所有内容都是DbCommand,那么您将必须显式关闭DbConnection,就像您目前在代码中所做的那样.然而,仅仅打电话就足够了Dispose.你不需要同时调用Close和Dispose.
