我已经在Visual Studio 2008上创建了我的项目，以及在其上的RDLC文件。
但是现在，当我在Visual Studio 2010上打开解决方案并想要打开RDLC文件时，它向我显示警告。
有点可笑。该报告是在VS2008上创建的，而VS2010要求转换为2008格式。也许我的VS2008安装存在问题，该问题使用某种古老的格式创建了RDLC文件(2005 ??!)。
问题是，当您单击“确定”按钮确认时，进行一些设计调整并运行该应用程序，会在“主报告”上引发错误:
ex.InnerException

最佳答案
将rdlc的早期版本转换为VS2010时遇到类似的问题。转换很好，需要进行的操作是必须将对Microsoft.ReportViwer.Common的引用从版本9更改为版本10。对Microsoft.ReportViewer.WebForms也执行相同的操作。您还需要在web.config和包含ReportViewer控件的页面中将版本9的所有引用更改为版本10。这解决了我的所有问题，并且能够在VS2010中修改报告。
关于visual-studio-2008 - Visual Studio 2010是否要求将在VS2008上创建的RDLC转换为RDLC 2008格式？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/2906626/
