У меня есть простой .rdlc файл, в котором определен параметр. Когда я заполняю (отправляю) значение параметра, я получаю сообщение об ошибке:
Failed to load expression host assembly.
Details: Type 'System.Web.HttpContextWrapper'
in assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
is not marked as serializable.
однако, удаляя значение параметра, отчет без проблем выводится.
ReportViewer1.LocalReport.DataSources.Clear();
ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Report/report1.rdlc");
//If following line commented, there is no problem,
//and report is rendered correctly.
ReportViewer1.LocalReport.SetParameters(new ReportParameter("test1", "some value"));
ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("DataSet1", Data));
ReportViewer1.DataBind();
target .net framework: 4.5.2, проект - веб-форма asp.net (веб-приложение), Microsoft.ReportingServices.ReportViewerControl.WebForms версия 140.1000.523 добавлена nuget.
обновление
Я добавил System.Web как ссылку на файл rdlc, и теперь получаю полную ошибку:
[SerializationException: Type 'System.Web.HttpContextWrapper' in assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable.]
