Reader.Read是一种将记录推进到下一个并返回布尔值的方法。如果预付款成功，则返回true，否则返回false。因此，Reader.Read会在循环的每次迭代中自动推进记录。如果你需要在你的循环中推进记录 - 在你需要预先的位置添加Reader.Read行。

感谢您提供信息，

我担心的是我需要将记录移动到我的表的下一行。

所以你基本上想要在For Each Row的下一次迭代中继续循环...等等等等等等。你已经有了For Each推进你的行...所以只需继续你的循环将退出到下一次迭代

Reader.Read is a method that advances the record to the next and returns a boolean. If an advance was successful, true is returned, if not, false is returned. Consequently While Reader.Read automatically advances the record on every iteration of your loop. If you need to advance the record inside your loop - add the line Reader.Read in the position you need the advance.

Thank you for the information,
My concern is I need to move the record to the next row of my table.

So you basically want to continue your loop at the next iteration of your For Each Row...blah blah blah. You''ve already got a For Each advancing your rows...so just Continue For your loop will exit to the next iteration
