Question

我开发了网络应用程序。我在服务器上没有办公室，并希望在那里部署我的发布文件夹。

微软办公室对于OWC是疯狂的吗？如果有，我们可以在没有安装excel的情况下使用它吗？

它给出错误

Server Error in '/owc' Application.

Could not load file or assembly 'owc' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Answer 1

错误消息表示文件owc.dll或其中一个引用丢失。

检查文件是否为：

位于您的网站项目的bin文件夹中（发布后）;
（C：\ windows \ assembly）。

如果它确实存在，您可以使用Reflector或类似产品查看owc.dll的引用是什么，您也必须检查这些引用。
