在 web.config 中手动添加 ReportViewer 程序集

Question

我正在尝试将 ReportViewer 程序集添加到我的 web.config 文件中。我放置了两个取自该目录的 dll：

• 来自 C:\Program Files 的 Microsoft.ReportViewer.WebForms.dll (x86)\Microsoft Visual Studio 12.0\ReportViewer

• 来自 C:\Program Files\Microsoft
  的 Microsoft.reportviewer.common.dll Office\Office15\ADDINS\PowerPivot Excel 插件

但是当我运行我的网页时它显示错误。

Line 14:     <compilation debug="true" strict="false" explicit="true" targetFramework="4.0">
Line 15:      <assemblies>
Line 16:         <add assembly="Microsoft.ReportViewer.WebForms" />
Line 17:         <add assembly="Microsoft.ReportViewer.Common" />
Line 18:       </assemblies>

程序集堆栈跟踪是：

你的网络配置应该有类似于下面的项目。

    <assemblies>            
            <add assembly="Microsoft.ReportViewer.Common, Version=14.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91" />
            <add assembly="Microsoft.ReportViewer.WebForms, Version=14.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91" />
    </assemblies>

 <buildProviders>
        <add extension=".rdlc" type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.WebForms, Version=13.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91" />
      </buildProviders>

 <handlers>
      <add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=14.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
    </handlers>


<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Microsoft.ReportViewer.WebForms" publicKeyToken="89845dcd8080cc91" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-14.0.0.0" newVersion="14.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

The Report Viewer Web Control HTTP Handler has not been registered in the application's web.config file
