Uwagi

The LocalReport class represents reports that are processed and rendered locally without connecting to a report server.This class is the same object that is used by the ReportViewer control, but it also can be used independently as a non-visual object that encapsulates the core functionality of the ReportViewer control.

The LocalReport object can open client report definition (RDLC) files from the file system or from embedded resources, or the RDLC file can be supplied to it as a Stream or a TextReader.

The LocalReport object does not have the ability to execute queries or fetch data; instead data sources must be added to the DataSources collection property.

The LocalReport object supports report parameters, but does not support parameter prompts

Przykłady

In the following code example, a LocalReport object is used to load and export a report.

protected void Button1_Click(object sender, EventArgs e)
{

   Microsoft.Reporting.WebForms.LocalReport lr = 
     new Microsoft.Reporting.WebForms.LocalReport();

   string deviceInfo =
     "<DeviceInfo>" +
     "<SimplePageHeaders>True</SimplePageHeaders>" + 
     "</DeviceInfo>";

   lr.ReportPath = @"C:\My Reports\Monthly Sales.rdlc";

   lr.DataSources.Add(new ReportDataSource("Sales", GetSalesData()));

   byte[] bytes = lr.Render("Excel", deviceInfo, out mimeType, 
     out encoding, out streamids, out warnings);

      using (FileStream fs = new FileStream(@"c:\My Reports\Monthly Sales.xls", FileMode.Create))
      {
        fs.Write(bytes, 0, bytes.Length);
      }
}

Protected Sub Button1_Click(ByVal sender As Object, _
   ByVal e As System.EventArgs) Handles Button1.Click
   Dim warnings As Warning() = Nothing
   Dim streamids As String() = Nothing
   Dim mimeType As String = Nothing
   Dim encoding As String = Nothing
   Dim extension As String = Nothing
   Dim deviceInfo as string
   Dim bytes As Byte()

   Dim lr As New Microsoft.Reporting.WebForms.LocalReport

   lr.ReportPath = "C:\My Reports\Monthly Sales.rdlc"

   lr.DataSources.Add(New ReportDataSource("Sales", GetSalesData()))

   deviceInfo = _
"<DeviceInfo><SimplePageHeaders>True</SimplePageHeaders></DeviceInfo>"

   bytes = ReportViewer1.LocalReport.Render("Excel", deviceInfo,_
      mimeType, encoding, extension, streamids, warnings)

   Dim fs As New FileStream("c:\output.xls", FileMode.Create)
   fs.Write(bytes, 0, bytes.Length)

End Sub
