我在我的 asp.net(vb) 网站中出现以下 7 个错误。它们发生在我根据此SO 帖子添加对 Microsoft Office 12.0 对象库的引用以尝试读取单个 Excel 工作表单元格之后。现在整个网站无法建立。最令人惊讶的是，当我在项目中不需要水晶报告时，为什么会收到与水晶报告相关的错误？

以下是7个错误：

去这个位置

[Windows Partition]:\Windows\Microsoft.NET\Framework\v4.0.30319\ASP.NETClientFiles\crystalreportviewers13\

打开 preview.aspx 文件，然后更改12.0.2000.0为13.0.2000.0

有用 ;-）

除了修复[Windows Partition]:\Windows\Microsoft.NET\Framework\v4.0.30319\ASP.NETClientFiles\crystalreportviewers13\文件夹中的 preview.aspx 外，您还应该在网站根目录中查找名为 aspnet_client 的文件夹，并在那里应用相同的更改。

如果您在 IIS 中使用多个网站，而不仅仅是“默认网站”，它会将 Crystalreportviewers13 文件夹复制到每个网站中，因此请全部检查。
