我的asp项目有一个非常奇怪的问题。当我在本地主机上测试时，我的项目可以顺利运行。但是当我部署到服务器时

它给了我这个错误

        ApplicationException: Object reference not set to an instance of an object.]
       LewreERP_MixsolProject.Module.Sales.SalesOrder.SalesOrderListing.createGridView() in C:\Users\user\Desktop\30052012\LewreERP_MixsolProject\Module\Sales\SalesOrder\SalesOrderListing.aspx.cs:309

            <!-- end of rightColumnModule2 -->
        </div>
    </ContentTemplate>
</asp:UpdatePanel>

我非常确定我已经删除了一个函数名createGridView()并且我还注释了 pageLoad 方法中的所有函数。

我尝试清除并重建解决方案，但仍然保留相同的错误。请帮忙 。谢谢

你调用的对象是空的

告诉您程序中的变量之一是null.

线

LewreERP_MixsolProject.Module.Sales.SalesOrder.SalesOrderListing.createGridView() 在 C:\Users\user\Desktop\30052012\LewreERP_MixsolProject\Module\Sales\SalesOrder\SalesOrderListing.aspx.cs:309

告诉您源代码中的哪一行有一个值为空的变量。

很可能问题不在于您不再在 localhost 上运行，而是在此新服务器上采用不同路径的代码或数据库中的数据不同。

更新

在您的评论中，您说您已经删除了createGridView(). 但是，该功能显然是在服务器上运行的。

这意味着您没有在服务器上运行最新的代码。
