Question

我正在使用RDLC文件呈现报告（没有SQL Server Reporting Services）并将其作为文件从我的控制器返回。这是我的MVC Web应用程序的一部分。

    public ActionResult Index()
    {
        var report = new LocalReport();
        report.ReportPath = Path.Combine(Server.MapPath("~/Reports"), "Report1.rdlc");
        var reportData = new List<MonthlyData> {
            new MonthlyData {RecordNo=1, Tid="123456", Active=10, Inactive=1}
        };
        ReportDataSource rd = new ReportDataSource("DataSet1", reportData);
        report.DataSources.Add(rd);
        string reportType = "PDF";
        string mimeType;
        string encoding;
        string fileNameExtension;


        string deviceInfo =

            "<DeviceInfo>" +
            "  <OutputFormat>" + "PDF" + "</OutputFormat>" +
            //"  <PageWidth>8.5in</PageWidth>" +
            //"  <PageHeight>11in</PageHeight>" +
            //"  <MagroupinTop>0.5in</MagroupinTop>" +
            //"  <MagroupinLeft>1in</MagroupinLeft>" +
            //"  <MagroupinRight>1in</MagroupinRight>" +
            //"  <MagroupinBottom>0.5in</MagroupinBottom>" +
            "</DeviceInfo>";

        Warning[] warnings;
        string[] streams;
        byte[] renderedBytes;

        renderedBytes = report.Render(
            reportType,
            deviceInfo,
            out mimeType,
            out encoding,
            out fileNameExtension,
            out streams,
            out warnings);

        return File(renderedBytes, mimeType);
    }

结果如下：

在我决定添加图表之前，一切都像魅力一样。

rdlc file with chart

现在当我渲染它时，我有两个例外：

Microsoft.Reporting.WebForms.LocalProcessingException: „An error occurred during local report processing.”

DefinitionInvalidException: The definition of the report 'C:\Users\agutowski\Documents\Visual Studio 2017\Projects\rdlcMvc\rdlcMvc\Reports\Report1.rdlc' is invalid.

和

Microsoft.Reporting.WebForms.LocalProcessingException: „An error occurred during local report processing.”

ReportProcessingException: The definition of this report is not valid or supported by this version of Reporting Services. The report definition may have been created with a later version of Reporting Services, or contain content that is not well-formed or not valid based on Reporting Services schemas. Details: The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition' which cannot be upgraded.

我已经尝试过不同版本的Microsoft.ReportViewer.Common和Microsoft.ReportViewer.WebForms。

Answer 1

我使用Microsoft.ReportingServices.ReportViewerControl.WebForms和Microsoft.SqlServer.Types NuGet包而不是Microsoft.ReportViewer.Common和Microsoft.ReportViewer.WebForms解决了这个问题。
