Excel下载无法在服务器/站点中工作，但可以在本地系统中工作 [英] Excel Download Not working in Server/Site but working in Local System

问题描述

我们有一个站点，可以选择下载Excel报告，最近，我们已将其从.net 2.0迁移(使用VS 2010)到4.0，并且托管服务器也已更改.该服务器与以前的服务器相同，该服务器为2003，并安装了MS Excel.但是相同的代码在我的本地系统(XP，VS-2010)中也可以正常工作.当我单击按钮下载excel时，出现以下错误.

异常详细信息:System.NullReferenceException:对象引用未设置为对象的实例.

我在这里http://forums.asp.net/p/1303594/3359738.aspx#3359738遵循了说明.之后，它工作正常.但是同样会发生同样的错误.我们已经在项目中使用了Interope.Excel dll.

如果您知道，请告诉我解决方案.谢谢. .
