我有一个较旧的项目,我想在其中打开一个 Word 文档并对其执行搜索和替换。它以前在我有较旧的 Visual Studio 和 Office 时工作,但现在我在 VS 2012 中遇到问题(安装了 Office 2013)。
我引用“Microsoft Word 15.0 对象库”COM 引用,我得到 3 个 dll 文件:
Microsoft.Office.Core
Microsoft.Office.Interop.Word
VBIDE
我的最小测试代码:
using Word = Microsoft.Office.Interop.Word;
...
object fileName = Path.Combine(System.Windows.Forms.Application.StartupPath, "document.doc");
Word.Application wordApp = new Word.Application { Visible = true };
Word.Document aDoc = wordApp.Documents.Open(ref fileName, ReadOnly: true, Visible: true);
aDoc.Activate();
Word.Find fnd = wordApp.ActiveWindow.Selection.Find;
fnd.ClearFormatting();
fnd.Replacement.ClearFormatting();
fnd.Forward = true;
fnd.Wrap = Word.WdFindWrap.wdFindContinue;
fnd.Text = "aaa";
fnd.Replacement.Text = "bbb";
fnd.Execute(Replace: Word.WdReplace.wdReplaceAll);
此代码运行并打开文档,但随后发生此异常:
System.Runtime.InteropServices.COMException was unhandled
HelpLink=wdmain11.chm#37373
HResult=-2146823683
Message=This command is not available.
Source=Microsoft Word
ErrorCode=-2146823683
StackTrace:

到底是怎么回事?我还有一个问题:如果我使用 v15.0 的 Interop 程序集(我想我的 Office 2013 附带),相同的代码是否可以在安装了以前版本的 Word 的机器上工作 - 比如 Office 2010?
