不需要水晶报表的asp.net vb中的Crystal reports错误

Question

我在我的asp.net(vb) website.They中得到以下7个错误，在我按照this SO post添加对Microsoft Office12.0对象库的引用后，试图读取单个excel工作表单元格。现在整个网站都建不起来了。最令人惊讶的是，为什么我在我的项目中不需要水晶报表的时候，却得到了一个与水晶报表相关的错误？

以下是7个错误：

任何帮助都是非常受欢迎的！

Answer 1

转到此位置

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

打开preview.aspx文件，将12.0.2000.0更改为13.0.2000.0

它可以工作;-)

Answer 2

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

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，因此请检查所有网站。
