使用水晶报表时出现问题 [英] Problem using crystal reports

问题描述

大家好！

我正在尝试使用Crystal Reports生成报告.

当我构建解决方案时，它向我显示错误

Hi all!!

I am trying to generate a report using crystal reports.

when i build the solution it shows me error that

The type ''CrystalDecisions.Web.CrystalReportViewer'' exists in both ''c:\Windows\assembly\GAC_MSIL\CrystalDecisions.Web\13.0.2000.0__692fbea5521e1304\CrystalDecisions.Web.dll'' and ''c:\Windows\assembly\GAC_MSIL\CrystalDecisions.Web\10.5.3700.0__692fbea5521e1304\CrystalDecisions.Web.dll''	C:\Users\Ujjwal\Documents\Visual Studio 2010\WebSites\4.0\Crystal\Default.aspx

当我删除引用时，它向我显示:

when i remove the reference, it shows me that:

The type ''CrystalDecisions.CrystalReports.Engine.ReportDocument'' exists in both ''c:\Windows\assembly\GAC_MSIL\CrystalDecisions.CrystalReports.Engine\10.5.3700.0__692fbea5521e1304\CrystalDecisions.CrystalReports.Engine.dll'' and ''c:\Windows\assembly\GAC_MSIL\CrystalDecisions.CrystalReports.Engine\13.0.2000.0__692fbea5521e1304\CrystalDecisions.CrystalReports.Engine.dll''

之后，它向我显示了无效的报告来源.

我正在使用代码项目文章来撰写此报告
在Visual Studio 2010中使用Crystal Reports生成报告 [ ^ ]

请帮帮我，我很久以来一直被困在这里，似乎找不到合适的解决方案.

after that it shows me invalid report source.

I am using a code project article to make this report

Please help me out i am stuck here from ages and can''t seem to find a suitable solution.

推荐答案

因为您在同一解决方案中添加了不同的Crystal报表引用. ......只取更新的一个...我希望它能解决Ur问题....

Because u added different Crystal report references in same solution....... Take only the updated one ... i hope it will solve Ur problem....

听起来您的应用程序引用了两个版本v13.0和v10.5.您需要确保您的应用程序仅引用一个版本的CR.

删除不需要的一个引用，并检查Web.Config文件中是否只有一个引用-您需要的一个引用.
清除缓存.清理然后重新构建应用程序.

It sounds like your application has references to two versions v13.0 & v10.5. You need to make sure that your application is only referencing one version of CR.

Remove one reference not needed and check Web.Config file that only one reference is present - the one which you need.
Clear your cache. Clean and then rebuild the application.

我试图更改web.config中的程序集引用，但是即使我删除了所有的v10.5引用，它也无法正常工作也适用于v13.

然后我只在.aspx页面中更改了版本，它就起作用了..:)

I was trying to change the assembly reference in web.config but it didn''t worked even when i have removed all the v10.5 references which were also there for v13.

Then i only change the version in my .aspx page and it worked.. :)
