仅在尝试使用 Word DocumentClass 时在 prod 中出现对象引用错误 [英] Getting a Object Reference error in prod only when trying to use the Word DocumentClass

问题描述

我正在编写一个使用 .dotx 模板并在 aspx 页面中合并数据的程序.该程序在我本地的 Dev 工作站上运行良好，但是当我将它部署到测试 IIS 服务器时，它在下面的第二行失败，给我一个对象引用错误.

I am writing a program that uses a .dotx template and does a merge of data in an aspx page. The program works perfect on my Dev workstation locally but when I deploy it to a test IIS server, it fails on the second line below giving me an Object Reference error.

我之前遇到过问题，因为 Word Com 对象不在 IIS 服务器上，所以我将 Word 加载到服务器上并在 DCom 中设置了权限并解决了该问题.但是现在我在以 wRange = ..... 开头的行上收到了这个错误.

I ran into problems earlier because the Word Com object was not on the IIS server so I loaded Word onto the server and set permission in DCom and got past that problem. But now I get this error on the line that starts with wRange = .....

正如我所说，该程序在调试模式下可以在本地完美运行.

As I said, the program works perfectly locally in debug mode.

有什么想法吗?

Microsoft.Office.Interop.Word.DocumentClass

System.NullReferenceException: Object reference not set to an instance of an object

代码行:

Document BaseDocument = oWord.Documents.Open(ref oTemplate, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing);

wRange = BaseDocument.Bookmarks.get_Item(ref endOfDoc).Range;
