推荐答案

您的代码没有错.当您在项目中引用了不同版本的CR dll时，通常会出现此错误.再次检查并确认您使用的版本正确.应该可以解决您的问题.

There is nothing wrong in the code that you have. This error usually is seen when you have different versions of CR dlls being referenced in your project. Check and verify again that you are using correct version..that should solve your problem.

作为prdshukla回答的补充，您可能要检查Server.MapPath("CrystalReport2.rpt)是实际的文件夹路径，并且存在.听起来很明显，但是您不想知道有多少人在下午调试文件名时丢失了C:\ MyFolder \ \ MyFile.rpt或C:\ MyFolderMyFile.rpt (没有\)，甚至C:\ MyFolder \ MyFile.rpt \
还要确保在尝试加载报表时未在CrystalReports中打开该报表.不确定所有版本是否有问题，但您最好确保.

As an addition to prdshukla''s answer you might want to check if the Server.MapPath("CrystalReport2.rpt") is an actual folder path and exists. It sounds so obvious, but you don''t want to know how many people have lost afternoons debugging filename''s such as C:\MyFolder\\MyFile.rpt or C:\MyFolderMyFile.rpt (no \) or even C:\MyFolder\MyFile.rpt\
Also make sure the report is not open in CrystalReports when trying to load it. Not sure if it''s a problem with all versions, but you''d best make sure.
