     using CrystalDecisions.Shared; 4、Pull模式下使用水晶报表    1）创建rpt文件    2）拖放CrystalReportViewer    3）绑定 5、读取水晶报表文件    private void ReadCRV(cryatalReportViewer crv)    {      openFileDialog dlg=new OpenFileDialog();      dlg.Title="打开水晶报表文件";      dlg.Filter="水晶报表文件(*.rpt)|*.rpt|所有文件|*.*";      if(dlg.showDialog()==DialogResult.OK)      {        crv.ReportSource=dlg.FileName;      }    } 6.
