您应该在Web.config文件中添加下一节：

 ＆LT;＆运行GT;
    ＆LT; assemblyBinding的xmlns =瓮：架构 - 微软COM：asm.v1＆GT;
      ＆LT; dependentAssembly＆GT;
        ＆LT; assemblyIdentity名称=System.Web.Mvc公钥=31bf3856ad364e35/＆GT;
        ＆LT; bindingRedirect oldVersion =1.0.0.0-2.0.0.0NEWVERSION =3.0.0.1/＆GT;
      ＆LT; / dependentAssembly＆GT;
    ＆LT; / assemblyBinding＆GT;
  ＆LT; /运行＆GT;

    @Html.Stimulsoft().StiMvcViewer("MyViewr", new StiMvcViewerOptions()
  {
      ActionGetReportSnapshot = "FromLoadFileReport",
      ActionViewerEvent = "ViewerEvent",
      Width = Unit.Percentage(100)
      //Theme = StiTheme.Office2007Black,
      //ActionPrintReport = "PrintReport",
      //ActionExportReport = "ExportReport",
      //ToolbarBackgroundColor = System.Drawing.Color.Silver



  StiReport report = new StiReport();
        string Path = Server.MapPath("~" + ("/Web/Areas/RepUser/HistoryJob.mrt"));
        report.Load(Path);
        report.Compile();

        return StiMvcViewer.GetReportSnapshotResult(HttpContext, report);

You should add next section in Web.config file:

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="3.0.0.1" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
