Question

通过Crystal Reports以外的ASP.NET应用程序创建PDF文件需要什么？

Answer 1

您可以使用iText＃，它基于类似的Java项目。

您不需要将Crystal Reports与此结合使用。如果你需要更强大（但价格昂贵）的东西，我已经用复杂的PDF来取得巨大成功：

Answer 2

一个可能的库是iTextSharp。显然iText是一个巨大的交易，但我在使用iTextSharp的要求时并没有真正看到它，但那是几年前。

Answer 3

最简单的方法是使用第三方库。我过去使用过ASPOSE.PDF并且效果很好。

我也试过它的开源PDF Sharp，但不是那么灵活。

protected void btnReport_Click(object sender, EventArgs e)

{

    showReport();

}

private void showReport()

{

    DataTable dat = Reports.getPartyWiseJobStatusReport(Convert.ToInt16(ddlDivName.SelectedValue), Convert.ToInt16(ddlJobGroup.SelectedValue), Convert.ToInt16(ddlProjectStatus.SelectedValue));

    ReportDocument rptdoc = new ReportDocument();

    string path = Server.MapPath("~/Reports/rptPartyWiseJobStatus.rpt");

    rptdoc.Load(path);

    rptdoc.SetDataSource(dat);

    //rptdoc.SetParameterValue(0, ddlDivName.SelectedItem.Text);
    //ExportOptions exportOpts1 = rptdoc.ExportOptions;
    rptdoc.ExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;

    rptdoc.ExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;

    rptdoc.ExportOptions.DestinationOptions = new DiskFileDestinationOptions();

    ((DiskFileDestinationOptions)rptdoc.ExportOptions.DestinationOptions).DiskFileName = Server.MapPath("~/Reports/rptPartyWiseJobStatus.pdf");

    rptdoc.Export();

    rptdoc.Close();

    rptdoc.Dispose();

    Response.ClearContent();

    Response.ClearHeaders();

    Response.ContentType = "application/pdf";

    Response.AppendHeader("Content-Disposition", "attachment; filename=rptPartyWiseJobStatus.pdf");

    Response.WriteFile("~/Reports/rptPartyWiseJobStatus.pdf");

    Response.Flush();

    Response.Close();

    File.Delete(Server.MapPath("~/Reports/rptPartyWiseJobStatus.pdf"));

}

public static DataTable getPartyWiseJobStatusReport（Int16 DivisionID，Int16 JobGroup，Int16 ProjectStatus）

{ string _procName =“sp_T_Proposal_SelectPartyWiseJobStatus”;

    DataTable dt1 = new DataTable();

    Database objDatabase = DatabaseFactory.CreateDatabase();

    DbCommand objDbCommand = objDatabase.GetStoredProcCommand(_procName);

    objDatabase.AddInParameter(objDbCommand, "@DivisionID", DbType.Int16, DivisionID);

    objDatabase.AddInParameter(objDbCommand, "@JobGroup", DbType.Int16, JobGroup);

    objDatabase.AddInParameter(objDbCommand, "@ProjectStatus", DbType.Int16, ProjectStatus);

    using (IDataReader dr = objDatabase.ExecuteReader(objDbCommand))

    {

        dt1.Load(dr);

    }

    return dt1;

}
