Lesson 3: Load a Report Definition from the Report Server

Topic Status: Some information in this topic is preview and subject to change in future releases. Preview information describes new features or changes to existing features in Microsoft SQL Server 2016 Community Technology Preview 2 (CTP2).

After you have created your project and generated the classes from the RDL schema, you are ready to load a report definition from the report server.

To load a report definition

  1. Add a private field at the top of the ReportUpdater class (module if you are using Visual Basic) for the Report class. This field will be used to maintain a reference to report that is loaded from the report server for the life of the application.

    private Report _report;

    Private m_report As Report
  2. Replace the code for the LoadReportDefinition() method in the Program.cs file (Module1.vb for Visual Basic) with the following code:

    private void LoadReportDefinition()
        System.Console.WriteLine("Loading Report Definition");
        string reportPath = 
            "/AdventureWorks 2012 Sample Reports/Company Sales 2012";
        // Retrieve the report defintion 
        // from the report server
        byte[] bytes = 
        if (bytes != null)
            XmlSerializer serializer = 
                new XmlSerializer(typeof(Report));
            // Load the report bytes into a memory stream
            using (MemoryStream stream = new MemoryStream(bytes))
                // Deserialize the report stream to an 
                // instance of the Report class
                _report = (Report)serializer.Deserialize(stream);

    Private Sub LoadReportDefinition()
        System.Console.WriteLine("Loading Report Definition")
        Dim reportPath As String = _
            "/AdventureWorks 2012 Sample Reports/Company Sales 2012"
        'Retrieve the report defintion 
        'from the report server
        Dim bytes As Byte() = _
        If Not (bytes Is Nothing) Then
            Dim serializer As XmlSerializer = _
                New XmlSerializer(GetType(Report))
            'Load the report bytes into a memory stream
            Using stream As MemoryStream = New MemoryStream(bytes)
                'Deserialize the report stream to an 
                'instance of the Report class
                m_report = CType(serializer.Deserialize(stream), _
            End Using
        End If
    End Sub

In the next lesson, you will write code to update the report definition that was loaded from the report server. See Lesson 4: Update the Report Definition Programmatically.
