Microsoft.Office.Core.MsoTriState引用问题

c#工程中添加了Microsoft.Office.Core引用之后,在程序中用到了Microsoft.Office.Core.MsoTriState,仍然出错:

错误 1 类型“Microsoft.Office.Core.MsoTriState”在未被引用的程序集中定义。必须添加对程序集“office, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c”的引用。 C:/Documents and 

错误 2 与“Microsoft.Office.Interop.PowerPoint.Presentations.Open(string, Microsoft.Office.Core.MsoTriState, Microsoft.Office.Core.MsoTriState, Microsoft.Office.Core.MsoTriState)”最匹配的重载方法具有一些无效参数

错误 3 参数“2”: 无法从“Microsoft.Office.Core.MsoTriState [c:/Documents and Settings/Administrator/我的文档/Visual Studio 2008/Projects/PPTPaser/ClassLibrary1/obj/Debug/Interop.Microsoft.Office.Core.dll]”转换为“Microsoft.Office.Core.MsoTriState []”

纠结了几个钟头,仍然不能解决,望各位大侠指点,感激不尽,会多给分的!

第一次在csdn上写文章.

因为要做一个提取ppt文字的工程,第一次接触Office开发.

以下是源码:

代码倒挺简单,但是添加引用废了我半天的力气.

首先是更改office2003的安装,参见msdn

http://msdn.microsoft.com/zh-cn/library/aa159923(office.11).aspx#EHAA

这样,你的引用中就会出现以下内容(当然有可能以前就有了,不用更改office2003的安装)

(1).net中有Microsoft.Office.Interop.PowerPoint, Office

(2)com中有Microsoft.Office 11.0(或12.0) Object library

Microsoft.Office.Interop.PowerPoint肯定是要添加的.

但Office和Microsoft.Office 11.0(或12.0) Object library添加谁?

只添加Office足以!

实践证明,

(1)如果只添加Microsoft.Office 11.0(或12.0) Object library,会出现下面的错误:

错误 1 类型“Microsoft.Office.Core.MsoTriState”在未被引用的程序集中定义。必须添加对程序集“office, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c”的引用

(2)如果Office和Microsoft.Office 11.0(或12.0) Object library都添加,就会出现下面的错误:

错误 1 类型“Microsoft.Office.Core.MsoTriState”同时存在于“E:/Program Files/Microsoft Visual Studio 9.0/Visual Studio Tools for Office/PIA/Office12/Office.dll”和“C:/Documents and Settings/Administrator/我的文档/Visual Studio 2008/Projects/PPTPaser/ConsoleApplication1/obj/Debug/Interop.Microsoft.Office.Core.dll”中

原因是MsoTriState在两个dll中都出现了.

正确做法:只添加Office引用即可

这个问题耗了我很多时间解决,因此特地写此文,希望遇到相同问题的程序员能尽快解决之.

关于com组件的和.net组件的添加还不是很清楚,希望大牛们指教.
