Question

我有一个Windows Forms应用程序，该应用程序使用本地rdlc文件生成报告。这是一个古老的应用程序，具有多年使用不同版本的rdlc设计器构建的报告（rdlc文件）。在最近的几周中，我已经迁移了该项目，并决定更新csproj文件以使用新的程序包引用格式。旧项目仍在使用旧版本的报表查看器控制，因此我决定遵循instructions并安装Microsoft.ReportingServices.ReportViewerControl.WinForms nuget包。查看csproj，我可以看到它引用了该软件包：

<PackageReference Include="Microsoft.ReportingServices.ReportViewerControl.Winforms">
  <Version>150.1358.0</Version>
</PackageReference>

不幸的是，现在我遇到了一些我不理解的错误。我遇到的第一个错误是报告格式无效。尽管显示了该消息，但似乎问题在于它缺少Microsoft.ReportViewer.ProcessingObjectModel程序集。

这是完整的堆栈错误消息：

Microsoft.Reporting.WinForms.LocalProcessingException: An error occurred during local report processing. ---> Microsoft.Reporting.DefinitionInvalidException: The definition of the report '' is invalid. ---> Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: An unexpected error occurred in Report Processing. ---> System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.ReportViewer.ProcessingObjectModel, Version=15.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies.

好吧，程序集丢失了（我已经确认它不在输出文件夹中）...

如果我没记错的话，当我使用package.config引用时，我必须更改程序集引用属性，以便将它们复制到输出中。不幸的是，VS中的程序集引用列表不再显示报告程序集（它将仅显示nuget包引用！），因此我不确定如何解决此问题。

编辑，只是要补充一点，我尝试将processingObjectModel程序集复制到输出中，但仍然遇到相同的错误。

EDIT2 我已经回到packages.config格式，并且可以正常工作...我有兴趣转向软件包参考，因此如果有人知道如何解决此问题（复制辅助程序到输出文件夹），请让我知道。

有任何线索吗？

谢谢！

您可以使用csproj中的以下代码段强制复制软件包lib \ net40内容：

<PackageReference Include="Microsoft.ReportingServices.ReportViewerControl.WebForms" GeneratePathProperty="true">

...

  <Target Name="CopySSRSPKG" AfterTargets="Build">
    <ItemGroup>
      <SSRSPKG Include="$(PkgMicrosoft_ReportingServices_ReportViewerControl_WebForms)\lib\net40\**\*.*" />
    </ItemGroup>
    <Copy SourceFiles="@(SSRSPKG)" DestinationFiles="@(SSRSPKG->'$(OutDir)\%(RecursiveDir)%(Filename)%(Extension)')" SkipUnchangedFiles="true" />
  </Target>
