运行时出错 [英] Error during run time

问题描述

使用这行代码



使用（rdr为mysqldatareader = cmd.executereader（））

我收到错误说rdr没有宣布。当我删除括号使它变成



使用rdr作为MySqlDataReader = cmd.ExecuteReader（）

我在这一行得到错误tmpObj .No = rdr（No）。ToString（）说No不是project.Form.Appdata的成员，这行tmpObj.Template = templa8和Template不是project.Form.AppData的成员。 />


我尝试过：



使用（rdr为mysqldatareader = cmd。 executereader（））

我收到错误，说没有声明rdr。当我删除括号使它变成



使用rdr作为MySqlDataReader = cmd.ExecuteReader（）

我在这一行得到错误tmpObj .No = rdr（No）。ToString（）说No不是project.Form.Appdata的成员，这行tmpObj.Template = templa8和Template不是project.Form.AppData的成员。

With this line of code

using (rdr as mysqldatareader = cmd.executereader())
I get an error saying rdr is not declared. When I remove the brackets so that it becomes

Using rdr As MySqlDataReader = cmd.ExecuteReader()
I get error on this line tmpObj.No = rdr("No").ToString()saying No is not a member of the project.Form.Appdata and this line tmpObj.Template = templa8 and Template is not a member of the project.Form.AppData.

What I have tried:

using (rdr as mysqldatareader = cmd.executereader())
I get an error saying rdr is not declared. When I remove the brackets so that it becomes

Using rdr As MySqlDataReader = cmd.ExecuteReader()
I get error on this line tmpObj.No = rdr("No").ToString()saying No is not a member of the project.Form.Appdata and this line tmpObj.Template = templa8 and Template is not a member of the project.Form.AppData.

推荐答案

您被告知问题所在： L使用（rdr as mysqldatareader = cmd.executereader（））rdr [ ^ ]

之后只是将你的代码转储给我们，并且基本上说我不知道我在做什么，你把它解决并不会让你在这里成为任何朋友。



虽然我很感激你要做的任务，这是你付出的代价，而不是我们 - 所以忽略明确说出问题所在的错误信息对你的案子没有帮助。



只是把你的整个代码丢给我们是非常粗鲁的。

You have been told what the problem is: L get this an error on this line using (rdr as mysqldatareader = cmd.executereader()) rdr[^]
Just dumping your code on us afterwards and basically saying "I don't know what I'm doing, you sort it out" isn't going to make you any friends here.

While I appreciate you have a task to do, it's what you are paid for, not us - so ignoring error messages that are explicit in saying what the problem is does not help your case.

And just throwing your entire code at us is plain rude.
