如何从 .Net Core 调用/引用 Crystal Reports

本文介绍了如何从 .Net Core 调用/引用 Crystal Reports的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个包含多个项目的 Visual Studio 解决方案.

I have a visual studio solution that has several projects in it.

• 解决方案
  • 领域层(类库> .Net Core 2.2)
    • 保存所有数据库模型
    • 保存与数据库的所有交互.我参考了 Microsoft.EntityFrameworkCore 和 Oracle.EntityFrameworkCore
    • 是应用的主要交互方式

    我正处于需要集成报告和打印报告的地步.我一直在我的应用程序中使用 Crystal Reports(非常成功).但是，由于 Crystal 需要 Framework 4.5，我不知道如何使其工作.

    I'm at the point where I need to integrate reporting and printing of reports. I've always used Crystal Reports for my applications (with good success). However, since Crystal requires Framework 4.5 I can't figure out how to make that work.

    我已经创建了我的报告对象并对其进行了测试.他们在自己的独立解决方案中工作得很好.一旦我在我的核心应用程序中引用了框架应用程序，我就会中断.特别是当我尝试创建一个 Crystal 'ReportDocument' 对象时，我会崩溃.我已经看到过 SO(并经过测试)，由于 DLL 不同，您不能将 .Net Core 与 .Net Framework 混合使用.

    I've created my Reporting objects and tested them. They work great in their own standalone solution. Once I reference the Framework app in my Core app I break. In particular I break when I attempt to create a Crystal 'ReportDocument' object . I've seen all over SO (and tested) you can't mix a .Net Core with .Net Framework because of the different DLLs.

    关于如何让报告/打印工作的任何建议?我对 Crystal Reports 也不挑剔.

    Any suggestions on how I can get reporting/printing to work? I'm not picky when it comes to Crystal Reports either.

    推荐答案

    你不走运，因为它不受支持.我鼓励您寻找其他替代方案

    You are out of luck, because it is not supported. I would encourage you looking into other alternatives

    来自 Crystal Reports 供应商网站:

    From the Crystal Reports vendor website:

    因此，将您的核心项目更新到完整的 4.7.1，它应该可以工作.我只安装了 4.7.1，它适用于我现有的设置为 4.0 的 ASP.NET 项目.

    So update your Core Project to the full 4.7.1 and it should work. I just install 4.7.1 and it works for my existing ASP.NET project that was set to 4.0.

    需要明确的是，不支持 Framework 2.0 Core

    To be clear, Framework 2.0 Core is NOT supported
