使用自定义对象进行RDL - SSRS（Reporting Services）

Question

我将VS 2008用于设计器RDL文件并在Report Server SSRS中进行部署。 我将VS 2012 .NET 4.5用于我的ASP.NET应用程序，以PDF或Excel格式呈现报告，并发送到浏览器。现在，我想将RDLC（本地报告）迁移到RDL。

我的问题：

我可以使用自定义对象（我的几个实体列表）作为远程报告（RDL）的来源吗？ ， 不是RDLC ？

我用

private ReportExecutionService reportExecutionService = new ReportExecutionService();   // Web Service proxy

 reportExecutionService.Credentials = CredentialCache.DefaultCredentials;
            reportExecutionService.Credentials = new NetworkCredential(Properties.Settings.Default.ReportBrowserUser
                , Properties.Settings.Default.ReportBrowserPass
                , Properties.Settings.Default.ReportBrowserDomain);

            //reportExecutionService.Url = System.Configuration.ConfigurationManager.AppSettings.Get("Reporting.ReportExecutionService.Url");
            reportExecutionService.Url = Reporting.Properties.Settings.Default.ReportExecutionServiceUrl;

            reportExecutionService.PreAuthenticate = true;
            reportExecutionService.ExecutionHeaderValue = new ExecutionHeader();

列出，我的实体为＆＃34;数据源＆＃34;填写我的报告：

  public void ProcessRequest(HttpContext context)
        {
            var empresa = Convert.ToInt32(context.Request["empresa"]);
            var mediador = Convert.ToInt32(context.Request["mediador"]);
            List<TablaEvolucionValorAnterior> listaPolizas = DatosGrafica.GetTablaEvolucionPolizasVentas(empresa, mediador);
            List<TablaEvolucionValorAnterior> listaPrimas = DatosGrafica.GetTablaEvolucionPrimasVentas(empresa, mediador);
            List<TablaRamosVentas> listaRamos = DatosGrafica.GetTablaRamosVentas(empresa, mediador);

RDLC

<DataSets>
    <DataSet Name="TablaRamosVentas">
      <Fields>
        <Field Name="Ramo">
          <DataField>Ramo</DataField>
          <rd:TypeName>System.String</rd:TypeName>
        </Field>

         ...

  <rd:DataSetInfo>
        <rd:ObjectDataSourceSelectMethod>GetTablaRamosVentas</rd:ObjectDataSourceSelectMethod>
        <rd:ObjectDataSourceSelectMethodSignature>System.Collections.Generic.List`1[Graficas.Entidades.TablaRamosVentas] GetTablaRamosVentas(Int32, Int32)</rd:ObjectDataSourceSelectMethodSignature>
        <rd:ObjectDataSourceType>Graficas.Bll.DatosGrafica, Graficas, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null</rd:ObjectDataSourceType>
      </rd:DataSetInfo>

</DataSet>

有关它的任何建议吗？

更新

我见过ReportExecution的Wrapper类：

https://github.com/aistrate/B4F/blob/f70276a5ac7d220b581d14e6d8e2f62d79083eea/TotalGiro/Reports/ReportExecutionWrapper.cs

GetReportContent方法管理一个DataSet，比如

            StringBuilder sb = new StringBuilder();
            StringWriter sw = new StringWriter(sb);
            ds.WriteXml(sw, XmlWriteMode.WriteSchema);
            sw.Close();

完整方法

        public byte[] GetReportContent(DataSet ds, string[] extraParams)
        {
            if (extraParams.Length != extraParamNames.Count)
                throw new ArgumentException(string.Format(
                    "[ReportExecutionWrapper] Wrong number of extra parameters passed in to method Run() [expected {0}, was {1}].",
                    extraParamNames.Count, extraParams.Length));

            initialize();

            StringBuilder sb = new StringBuilder();
            StringWriter sw = new StringWriter(sb);
            ds.WriteXml(sw, XmlWriteMode.WriteSchema);
            sw.Close();

            parameters[0].Value = sb.ToString();

            for (int i = 0; i < extraParams.Length; i++)
                parameters[i + 1].Value = extraParams[i];

            reportExecutionService.SetExecutionParameters(parameters, "nl-NL");

            string extension, mimeType, encoding;
            Warning[] warnings;
            string[] streamIds;
            byte[] reportContent = reportExecutionService.Render("PDF", "",
                                        out extension, out mimeType, out encoding, out warnings, out streamIds);
            return reportContent;
        }

在RDL文件中，https://github.com/aistrate/B4F/blob/f70276a5ac7d220b581d14e6d8e2f62d79083eea/Reports/Reporting%20Project/Reporting%20Project/Reporting%20Project/FiscalYearISB.rdl

定义ReportParameter＆＃34; DataSource＆＃34; （键入String）

  <ReportParameters>
    <ReportParameter Name="DataSource">
      <DataType>String</DataType>
      <DefaultValue>
        <Values>
          <Value>C:\Temp\Schemas\FiscalYearOverview.xml</Value>
        </Values>
      </DefaultValue>
      <Prompt>DataSource</Prompt>
      <Hidden>true</Hidden>
    </ReportParameter>

和DataSet如下：

<DataSet Name="TotalPortfolioValues">
      <Fields>
        <Field Name="Date">
          <DataField>Date</DataField>
          <rd:TypeName>System.DateTime</rd:TypeName>
        </Field>
            ...
      <Query>
        <DataSourceName>dsTotalGiro</DataSourceName>
        <CommandText>TotalPortfolioValues</CommandText>
        <QueryParameters>
          <QueryParameter Name="@DataSource">
            <Value>=Parameters!DataSource.Value</Value>
          </QueryParameter>
        </QueryParameters>
      </Query>
    </DataSet>

从BusinessObjectList创建DataSet并使用DataSet参数调用ReportExecution：

https://github.com/aistrate/B4F/blob/f70276a5ac7d220b581d14e6d8e2f62d79083eea/TotalGiro/ApplicationLayer/Reports/ReportResultsAdapter.cs

    public static byte[] ViewPrintedReports(int managementCompanyId, int year, string reportLetterTypeName)
    {
        DataSet dsPrintedReports = GetPrintedReportsDataSet(managementCompanyId, year, reportLetterTypeName);

        ReportExecutionWrapper wrapper = new ReportExecutionWrapper();
        wrapper.SetReportName(getReportTemplateName(managementCompanyId, ReportReturnClass.ResultOfPrintedReport.ToString()));
        wrapper.AddParameters(new string[] { "SelectedReportYear" });

        return wrapper.GetReportContent(dsPrintedReports, new string[] { year.ToString() });
    }

    // Also used by DumpDataSets.aspx
    public static DataSet GetPrintedReportsDataSet(int managementCompanyId, int year, string reportLetterTypeName)
    {
        IDalSession session = NHSessionFactory.CreateSession();
        try
        {
            ReportLetterTypes reportLetterType = ReportLetterMapper.GetReportLetterType(reportLetterTypeName);

            DataSet dsPrintedReports = DataSetBuilder.CreateDataSetFromBusinessObjectList(
                        ReportMapper.GetReports(session, year, reportLetterType, managementCompanyId),
                        @"Key, Account.Key, ReportLetter.Key, ReportStatusId, ReportLetter.ReportLetterYear, ReportLetter.ReportLetterTypeId, 
                          ModelPortfolio.Key, ModelPortfolio.ModelName");

            return getPrintedReportsSummary(dsPrintedReports);
        }
        finally
        {
            session.Close();
        }
    }
