hello everyone!
I have a problem everyone needs help.
I want to print a similar report three times. I tried and tried but it just check in once. I have the following code:

 private void button1_Click (object sender, EventArgs e)
        {
            try
            {
                / / Loadreport ("select * from CodeHanghoa");
                string [] = {noidung "Save your company", "delivery to the customer", "...................." };
                ParameterFields paramFields;

                ParameterField paramField;
                ParameterDiscreteValue paramDiscreteValue;

                / / ReportDocument = new ReportDocument ();


                DataSet ds = Loadreport ("select * from CodeHanghoa");
                for (int i = 0; i <3; i)
                {
                    ParameterFields paramFields = new ();

                    ParameterField paramField = new ();
                    CrystalReport1 CrystalReport1 rep = new ();
                    rep.Load ("CrystalReport1.rpt");

                    paramField.Name = "var11";
                    ParameterDiscreteValue paramDiscreteValue = new ();
                    paramDiscreteValue.Value = "Lien" (i 1) ":" noidung [i];
                    paramField.CurrentValues.Add (paramDiscreteValue);
                    / / Add the paramField to paramFields
                    paramFields.Add (paramField);
                    crystalReportViewer1.ParameterFieldInfo = paramFields;
                    rep.SetDataSource (ds);
                    crystalReportViewer1.ReportSource = rep;
                }
            }
}
catch
{

}

推荐答案

您未打印，正在显示报告.您还只需要重新分配ReportViewer.ReportSource三次，每次都覆盖之前的分配，而该分配没有完成.

You are not printing, you are displaying the report. You are also only reassigning the ReportViewer.ReportSource three times, each time overwriting the previous assignment which accomplished nothing.

您完全错了，正如Mark所说的，要打印多个副本，请调用PrintToPrinter方法.在代码中添加以下行

You are totally wrong as Mark said, For printing multiple copies call the PrintToPrinter method. Add the below line in your code

//public virtual void PrintToPrinter (int nCopies, bool collated, int startPageN, int endPageN);

rep.PrintToPrinter(3, False, 0, 0);

注意:从代码中删除循环，或仅将其用于参数块.

Note : Remove the Loop from your coding or make it only for your parameter block.
