本地报表处理过程中出错。报表'的定义无效

Question

我是使用 SSRS 的新手。我正在使用.rdlc 文件在带有 VS 2012 的 PDF 中生成报告。当我尝试设置类似的参数时

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

这会引发异常：

本地报告处理过程中出错。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'或一个其依赖项。访问被拒绝。

更多细节：

我错过了什么。在某些帖子中，建议使用缺少的Microsoft.ReportViewer.PorcessingObjectMode.dll。我这样做了，所以我拥有所有必需的 dll，例如：

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

在那里。

我提到了这个post。但我仍然无法完成这项工作。

第一次出现此错误，定义无效。 当我再次调试时，错误变为：

AspNetCore.Reporting.LocalProcessingException: An error occurred during local report processing.;The process cannot access the file

at ProjectName.Controllers.ReportController.ReportBrandingAsync(String Cabang, String DisplayProgram, String Brand, String DateFrom, String DateTo)

我尝试运行：

LocalReport localReport = new LocalReport(path);
localReport.AddDataSource("dsBranding", oResult);
var result = localReport.Execute(RenderType.Excel, extension, parameters, mimeType);

而且因为错误太奇怪了，改了两次但我什么也没做，于是我尝试检查我的磁盘C盘是否已满。

尝试删除一些文件以释放一些空间，并且不更改代码，报告再次正常

Answer 2

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 具有相同的版本。在 Web.config 中编辑它们的依赖关系，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 3

对我来说，这是因为我没有在项目中添加对报告程序集 (Microsoft.ReportViewer.*) 的引用。

由于某种原因，它在从 VS 运行时可以正常工作，但运行实际发布的站点会导致此错误。

Answer 4

简单的方法，进入你的属性

“.rdlc”文件并将构建操作更改为“内容”

, Copy To Output Directory to "Copy Always",

如果您更改了 "Microsoft.ReportViewer.WebForms" 、 "Microsoft.ReportViewer.ProcessingObjectModel" 、 "Microsoft.ReportViewer.Common" 的版本号

确保您进入属性并在属性下使特定版本为真。我们探索了所有解决方案，最后这奏效了。

Answer 5

在我的情况下，在本地环境中，报告正在工作，但在暂存环境中却没有。 原因是，我发布代码的文件夹本身没有 .rdlc 文件。这导致了这个错误。

1. 现在我将 .rdlc 文件复制粘贴到相应的暂存文件夹中，它可以正常工作。

或

1. 在发布您的应用程序之前，右键单击 .rdlc 文件并转到属性，然后选择 Build Action 下的内容。然后发布应用程序并检查文件夹，.rdlc 文件将在那里。

2. 现在将它从您的开发环境移动到其他环境。

希望这可能对某人有所帮助。

Answer 6

编辑： 解决方案似乎是未加载报告定义。例如可以通过

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，设置参数是特殊的。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。否则它会拒绝所有参数。

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

另一个问题可能是您在开发机器上使用的 ReportViewer 版本与在部署机器上使用的不同。
