推荐答案

SAP拥有自己的Crystal Reports社区网络.通常，如果将Crystal Reports与Visual Studio一起使用，则需要提供问题帖中使用的Visual Studio版本和年份以及Crystal Reports的年份(可能是版本)(或 他们发布问题)，以便偷窥可以帮助您.

SAP has their own community networks for Crystal Reports. Typically if using Crystal Reports with Visual Studio you would need to provide which Visual Studio edition and year and probably version of Crystal Reports being used within a question post (or however they post questions) so peeps can assist you.

您可以尝试SAP Crystal Reports，适用于Visual Studio的版本，在这种情况下，您需要加入我认为需要帮助的社区.

You could try SAP Crystal Reports, version for Visual Studio in which case you would need to join the community I think for asking for help.
