如何直接打印报表而无需使用Crystal Reports Viewer？

Question

我写了这段代码打印水晶报表，但是出现了错误。

“缺少参数”...

ReportDocument rdoc = new ReportDocument();
rdoc .Load (Application.StartupPath +"\\"+@"REPORTS\SalaryReport.rpt");

rdoc.SetDataSource(ds.Tables[0]);

ParameterFields pfs = new ParameterFields();

ParameterField pfv = new ParameterField();
ParameterDiscreteValue pdv1 = new ParameterDiscreteValue();
pfv.Name = "fd";
pdv1.Value = fd;
pfv.CurrentValues.Add(pdv1);
pfs.Add(pfv);

ParameterField pfv1 = new ParameterField();
ParameterDiscreteValue pdv11 = new ParameterDiscreteValue();
pfv1.Name = "td";
pdv11.Value = td;
pfv1.CurrentValues.Add(pdv11);
pfs.Add(pfv1);

ParameterField pfv2 = new ParameterField();
ParameterDiscreteValue pdv12 = new ParameterDiscreteValue();
pfv2.Name = "department";
pdv12.Value = Dept;
pfv2.CurrentValues.Add(pdv12);
pfs.Add(pfv2);
crystalReportViewer1.ParameterFieldInfo = pfs;
crystalReportViewer1.ReportSource = rdoc;

PrinterSettings getprinterName = new PrinterSettings();
rdoc.PrintOptions.PrinterName = getprinterName.PrinterName;
rdoc.PrintToPrinter(1, true, 1, 1);

帮助解决这个问题...如何直接打印而不经过Crystal Reports Viewer？

Answer 1

如此简单

1. Remove thes lines:

   crystalReportViewer1.ReportSource = objRpt;
   crystalReportViewer1.Refresh();
   

2. Add this line:

   objRpt.PrintToPrinter(1, false, 0, 0);

直接打印到打印机并不能解决您的问题。Crystal报表需要正确设置参数，但由于某种原因它们没有被设置好。

请使用PrintToPrinter方法直接打印水晶报表。

在我的报表中不使用ParameterFields意味着我可以得到输出，但是如果我使用ParameterFields，则会出现“缺少参数”的错误。 - Murali Bala

  List<BusLib.Report.ReportParameter> ParaList = new List<BusLib.Report.ReportParameter>();
            ParaList.Add(new BusLib.Report.ReportParameter("Para1", Value1));
            ParaList.Add(new BusLib.Report.ReportParameter("Para2", Value2));
            ParaList.Add(new BusLib.Report.ReportParameter("Para3", Value3));
            ParaList.Add(new BusLib.Report.ReportParameter("Para4", Value4));

然后...

public void SetParameters(List<BusLib.Report.ReportParameter> pParams)
    {
        if (pParams == null) { return; }
        try
        {
            foreach (BusLib.Report.ReportParameter pPara in pParams)
            {
                CReport.SetParameterValue(pPara.ParameterName, pPara.ParameterValue);
            }
        }
        catch (Exception Ex)
        {
            Val.Message(Ex.Message.ToString());
        }
    }

你应该尝试这个...你一定会成功的...

private void PrintReport(string reportPath, string PrinterName)
{
    CrystalDecisions.CrystalReports.Engine.ReportDocument rptDoc =
                        new CrystalDecisions.CrystalReports.Engine.ReportDocument();
    rptDoc.Load(reportPath);

    CrystalDecisions.Shared.PageMargins objPageMargins;
    objPageMargins = rptDoc.PrintOptions.PageMargins;
    objPageMargins.bottomMargin = 100;
    objPageMargins.leftMargin = 100;
    objPageMargins.rightMargin = 100;
    objPageMargins.topMargin = 100;
    rptDoc.PrintOptions.ApplyPageMargins(objPageMargins);
    //rptDoc.PrintOptions.PrinterName = PrinterName;
    rptDoc.PrintToPrinter(1, false, 0, 0);
}

private void PrintToPrinter()
{
    PrintReport(System.Windows.Forms.Application.StartupPath +"\\VCrpfrmprint.rpt","Send To OneNote 2010");
}

rptDoc.PrintToPrinter 方法将报表的指定页面打印到使用 PrintOptions.PrinterName 属性选择的打印机上。
如果未选择打印机，则将使用报表中指定的默认打印机。

我们正在使用以下方式的 PrintToPrinter 方法：

public void PrintToPrinter (int nCopies , boolean collated , int startPage , int endPage );

where:

• nCopies 表示要打印的副本数量。
• collated 表示是否整理页面。
• startPage 表示要打印的第一页。
• endPage 表示要打印的最后一页。

Answer 6

reportname report1=new reportname(); 
report1.PrintOptions.PaperOrientation = PaperOrientation.Portrait;
report1.PrintOptions.PaperSize = PaperSize.PaperA4;
report1.PrintToPrinter(1, false, 0, 15);

使用这些代码与函数（参数）一起使用

                return;
            }
        }
