问题描述

大家好，

它显示以下错误.

抱歉，回复晚了，这是我的配置文件，

Hi all,

While I bound data in the Datagridview in the Windows form application,
It shows the below error.

"An Error occurred while retrieving the information from the database

Failed to compare two elements in the Array"

What will be the error?

Also I am new to winforms.

Thanks in Advance.

推荐答案

看起来像您要比较的两个值不具有可比性.
在此处发布更多代码可能会有所帮助.

Looks like two values that you are trying to compare are not comparable.
Posting some more code here may help.
