开发端测试没有问题，但是发布至服务器之后，运行程序，即发生配置错误，未能加载“ Microsoft.ReportViewer.WebForms  ” 或者“Microsoft.ReportViewer.Common ”。

 解决与原因，是因为服务器没有找到相关的DLL组件，而在开发端能正确运行，是因为在安装VS2010时，已经有此DLL组件了。

因此可以在添加参考介面找到相关的DLL:

 

此时你会发现两个版本9.0和10.0版本，你拷贝开发时相对应的版本即可。拷贝到哪里？拷贝至程序集的BIN目录下。Insus.NET是10.0版本的，所以只取这两个Microsoft.ReportViewer.Common.dll 和Microsoft.ReportViewer.WebForms.dll
