将代码渲染为PDF格式 [英] Render code to PDF format

问题描述

Hai，



这是我的代码：

Hai,

This is my code:

DataTable dtDS = ds.Tables["tblDS"];
if (dtDS.Rows.Count != 0)
{
    DataRow dr = dtDS.Rows[0];

    ReportViewer viewer = new ReportViewer();
    viewer.ProcessingMode = ProcessingMode.Local;
    LocalReport lr = viewer.LocalReport;
    lr.ReportPath = ConfigUtil.GetAppSetting("DataSheetType_" + dr["DataSheetType"].ToString());
    ReportDataSource rds = new ReportDataSource();
    rds.Value = ds.Tables[0];
    rds.Name = "report";

    HTMLConverter rtf = new HTMLConverter();

    if (dr["SO1_Address"].ToString() != "")
    {
        dr["SO1_Address"] = rtf.HTML2RTF(dr["SO1_Address"].ToString(), 16);
    }

    lr.DataSources.Add(rds);                        

    string reportType = "PDF";
    string mimeType = "application/pdf";
    string encoding;
    string fileNameExtension = Guid.NewGuid().ToString() + ".pdf";

    string deviceInfo =
    "<DeviceInfo>" +
    "  <OutputFormat>PDF</OutputFormat>" +                        
     "</DeviceInfo>";

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

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

    Response.Clear();
    Response.ContentType = mimeType;
    Response.AddHeader("content-disposition", "attachment; filename=foo." + fileNameExtension);
    Response.BinaryWrite(renderedBytes);
    Response.End();
}

代码编译器在尝试执行lr.Render代码时返回异常。我不知道出了什么问题？



lr.ReportPath是一个rdlc报告文件。

The code compiler returns an exception while trying to execute the lr.Render code. I have no idea what's wrong?

lr.ReportPath is an rdlc report file.
