您在那里发布了很多代码，但您的问题并不十分清楚。你说你“抓不到原始ID”-你到底是什么意思？额外的方括号是打字错误吗<代码>GetActiveServiceKeys.Rows[[“ActiveServiceKeyId”]不清楚您为什么需要原始ID。代码正在更新或插入。同一组数据是否有多行，您需要“记住”或查找现有ID？如果有现有数据，我希望运行更新而不是插入。我的问题是，我无法获取每行的每个ID。方括号et输入错误是故意的。我不知道如何获取原始id来运行更新。嗯……我对LINQ不太熟悉。这是拖放代码吗？@Bry4n：当然，只需要将自己创建为新类MyDTO。还要确保2

askta

方法实际返回一个整数。您必须确保

GetActiveServiceKeys。行

位是正确的。@p.campbell

dt

需要更改为

temproutedatable

不是吗？@p.campbell我在

originalID

上得到一个错误，它说它需要

int

在

foreach

中@Bry4n:对，

dt

是我在测试中的本地代码。re:

originalID

。。。确保它在DTO中定义为字符串，并且

GetActiveServiceKeys.Rows

返回字符串。请参阅我更新的pastebin链接。
