本地报表处理期间发生错误。报表的定义“无效”

Question

我是使用 SSRS 的新手。我正在使用.rdlcVS 2012 生成 PDF 报告的文件。当我尝试设置如下参数时

ReportParameter param = new ReportParameter(kvp.Key, kvp.Value);
LocalReport.SetParameters(param);

这会引发异常：

本地报告处理期间发生错误。报告“”的定义无效。无法加载文件或程序集“System.Web，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b03f5f7f11d50a3a”或其依赖项之一。访问被拒绝。

更多细节：

我缺少什么。在一些帖子中，建议使用 Missing Microsoft.ReportViewer.PorcessingObjectMode.dll。我这样做了，所以我拥有了所有必需的 dll，例如：

-    Microsoft.ReportViewer.Common.dll
-    Microsoft.ReportViewer.WebForms.dll
-    Microsoft.ReportViewer.ProcessingObjectModel.dll

在那儿。

我参考了这篇文章。但我仍然无法完成这件事。

Answer 1

当我将应用程序部署到 azure 时，我遇到了同样的问题。经过几个小时的调试，我注意到 Microsoft.SqlServer.Types 与其他报告 dll 的版本不同。因此，您应该确保这些 dll 的版本相同。在 Web.config 中编辑它们的依赖项，如下所示

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
        <assemblyIdentity name="Microsoft.ReportViewer.DataVisualization" publicKeyToken="89845dcd8080cc91" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-11.0.0.0" newVersion="11.0.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="Microsoft.SqlServer.Types" publicKeyToken="89845dcd8080cc91" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-11.0.0.0" newVersion="11.0.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="Microsoft.ReportViewer.Common" publicKeyToken="89845dcd8080cc91" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-11.0.0.0" newVersion="11.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

Answer 2

编辑：解决方案似乎是报告定义未加载。例如可以通过以下方式完成

var reportStream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("ReportName.rdlc"); 
localReport.LoadReportDefinition(reportStream);

旧建议 - 此处不适用：

老实说，可能会有不同的事情。首先，参数设置比较特殊。如果您的项目在 .NET 4 或更高版本中运行，则报告引擎将在与您的应用程序不同的应用程序域中运行。所以你必须设置参数可以使用的权限。否则它拒绝所有参数。

var report = new LocalReport();
report.SetBasePermissionsForSandboxAppDomain(new PermissionSet(PermissionState.Unrestricted));

另一个问题可能是您在开发计算机上使用的 ReportViewer 版本与部署计算机上不同。
