在VS2010上编译水晶报表提示找提示以下错误：
Could not load file or assembly 'file:///C:\Program Files\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet1\crdb_adoplus.dll' or one of its dependencies. The system cannot find the file specified.
只要在App.config中的
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
改成
<startup useLegacyV2RuntimeActivationPolicy ="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
就可以了。
