c# - Microsoft.Office.Interop.Word 程序集版本高于引用版本

Question

出现以下错误的原因是什么:

Error 12 Assembly 'Microsoft.Office.Interop.Word, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' uses 'office, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' which has a higher version than referenced assembly 'office, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' c:\Program Files\Microsoft Visual Studio 10.0\Visual Studio Tools for Office\PIA\Office14\Microsoft.Office.Interop.Word.dll WindowsFormsApplication1

您的代码似乎引用了一个版本的 Office，但正在尝试使用不同的版本。这是一个很常见的问题，因为许多不同版本的 Office 都在使用中。

当我不得不使用 Office Interop 时，我通过使用 Late Binding 而不是 Early Binding 来避免这个问题。这意味着我不会添加对特定版本 Office 的引用，并且我的代码将适用于任何最新版本，只要我不使用仅存在于特定版本中的功能或类似功能即可。
