SQLHelper类-ExecuteNonQuery代码修改

发布于 2024-07-25 09:33:53 字数 1084 浏览 5 评论 0原文

我只是浏览 SQLHelper 类 V2 中的代码,我注意到以下内容:

    public static int ExecuteNonQuery(SqlTransaction transaction, CommandType commandType, string commandText, params SqlParameter[] commandParameters)
    {
        if( transaction == null ) throw new ArgumentNullException( "transaction" );
        if( transaction != null && transaction.Connection == null ) throw new ArgumentException( "The transaction was rollbacked or commited, please provide an open transaction.", "transaction" );

        // Create a command and prepare it for execution
        SqlCommand cmd = new SqlCommand();
        bool mustCloseConnection = false;
        PrepareCommand(cmd, transaction.Connection, transaction, commandType, commandText, commandParameters, out mustCloseConnection );

        // Finally, execute the command
        int retval = cmd.ExecuteNonQuery();

        // Detach the SqlParameters from the command object, so they can be used again
        cmd.Parameters.Clear();
        return retval;
    }

该命令不在“使用 Bolck”中是否有原因? 我在代码的其他地方看到了“使用块”的使用。

I am just browsing the code in the SQLHelper Class V2 and I notice the following

    public static int ExecuteNonQuery(SqlTransaction transaction, CommandType commandType, string commandText, params SqlParameter[] commandParameters)
    {
        if( transaction == null ) throw new ArgumentNullException( "transaction" );
        if( transaction != null && transaction.Connection == null ) throw new ArgumentException( "The transaction was rollbacked or commited, please provide an open transaction.", "transaction" );

        // Create a command and prepare it for execution
        SqlCommand cmd = new SqlCommand();
        bool mustCloseConnection = false;
        PrepareCommand(cmd, transaction.Connection, transaction, commandType, commandText, commandParameters, out mustCloseConnection );

        // Finally, execute the command
        int retval = cmd.ExecuteNonQuery();

        // Detach the SqlParameters from the command object, so they can be used again
        cmd.Parameters.Clear();
        return retval;
    }

Is there a reason why the command wasn't within a "Using Bolck"? I see the use of the"Using Block" elsewhere in the code.

我的猜测是,因为该命令在整个函数范围内使用,所以它只会添加额外的代码。 不同的开发人员喜欢不同的实现。

My guess is that its because the command is used throughout the scope of the function, so it would just add extra code. Different developer preferring different implementations.
