Question

我动态创建报告，即我无法打开设计器RDLC并修复它。我创建一个表并通过数据集填充它。获取XML文件并将其导出为PDF文件。但即使我写了

string deviceInfo =
"<DeviceInfo>" +
" <OutputFormat>PDF</OutputFormat>" +
" <PageWidth>11in</PageWidth>" +
" <PageHeight>8.5.0in</PageHeight>" +
" <MarginTop>0.05in</MarginTop>" +
" <MarginLeft>0.05in</MarginLeft>" +
" <MarginRight>0.05in</MarginRight>" +
" <MarginBottom>0.05in</MarginBottom>" +

" <KeepWithGroup>After</KeepWithGroup>" +
" <RepeatOnNewPage>true</RepeatOnNewPage>" + 
" <FixedData>true</FixedData>"+
 " <RepeatHeaderOnNewPage>true</RepeatHeaderOnNewPage>" +
"</DeviceInfo>";
try
{
 byte[] bytes = reportViewer1.LocalReport.Render(
 "PDF", deviceInfo, out mimeType, out encoding, out filenameExtension,
 out streamids, out warnings);

 using (FileStream fs = new FileStream(filename, FileMode.Create))
 {
 fs.Write(bytes, 0, bytes.Length);
 fs.Close();
 }
 return filename;
 }
 //....

我只在1页上看到标题帮助解决问题！谢谢！

    private Rdl.HeaderType CreateHeader()
    {
        Rdl.HeaderType header = new Rdl.HeaderType();
        header.Items = new object[]
            {

                Rdl.ItemsChoiceType20.RepeatOnNewPage,
            };
        return header;
    }

    public string ExportReport(string filename)
    {
        Warning[] warnings;

        try

            byte[] bytes = reportViewer1.LocalReport.Render(
                "PDF", deviceInfo, out mimeType, out encoding, out filenameExtension,                       out streamids, out warnings);

                fs.Close();
            }
            return filename;
        }
        catch (Exception e)
        {
            Program.WriteLogEx.WriterLogErr(e.Message);
            return "";
        }
    }
