使用Word互操作设置自定义文档属性 [英] Set custom document properties with Word interop

问题描述

我想设置一些用C#代码创建的Word文档的自定义文档属性.为此，我遵循了此MSDN文章，并提出了此代码:

I want to set some custom document properties of a word document I'm creating in my C# code. To do this, I followed this MSDN article and came up with this code:

using Word = Microsoft.Office.Interop.Word; // Version 12.0.0.0
word = new Word.Application();
word.Visible = false;
Word._Document doc = word.Documents.Add(ref missing, ref missing, ref missing, ref missing);
logger.Info("Setting document properties");
Core.DocumentProperties properties = (Core.DocumentProperties)doc.BuiltInDocumentProperties;
properties["Codice_documento"].Value = args[3];
properties["Versione_documento"].Value = args[4];

不幸的是，每当到达代码时，我都会收到此错误:

Unfortunately, I get this error whenever it reaches the code:

HRESULT:0x80004002(E_NOINTERFACE)

HRESULT: 0x80004002 (E_NOINTERFACE)

那是为什么?我完全按照我的MSDN所述使用了接口，为什么它不起作用?

Why is that? I used the interfaces exactly as described my MSDN, why doesn't it work?

我正在将Interop用于Office 2010和.net 3.5

I'm using Interop for office 2010 and .net 3.5

推荐答案

在

After asking the question in the MSDN forums, the answer was brought up. The problem is, that the way I tried was specific to VSTO. Due to my unknowing, I mixed up VSTO, Interop and other definitions, thus tagging this question wrong.

现在可以使用以下代码运行:

It now works using the following code:

logger.Info("Setting document properties");
object properties = doc.CustomDocumentProperties;
Type propertiesType = properties.GetType();

object[] documentCodeProperty = { "Codice_documento", false, Core.MsoDocProperties.msoPropertyTypeString, args[3] };
object[] documentVersionPoperty = { "Versione_documento", false, Core.MsoDocProperties.msoPropertyTypeString, args[4] };

propertiesType.InvokeMember("Add", BindingFlags.InvokeMethod, null, properties, documentCodeProperty);
propertiesType.InvokeMember("Add", BindingFlags.InvokeMethod, null, properties, documentVersionPoperty);
