报表问题!!!
private Microsoft.Reporting.WinForms.ReportViewer rvDuiXian;
TextReader stringReader = new StringReader (@"E:\Priject\VSS\SellManagement\SellManagement\Gather\DuiXiangMianJi.rdlc");
this.rvDuiXian.LocalReport.LoadReportDefinition(stringReader);
this.rvDuiXian.LocalReport.ReportPath = @"E:\Priject\VSS\SellManagement\SellManagement\Gather\DuiXiangMianJi.rdlc";
Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string extension;
this.rvDuiXian.LocalReport.Render("Excel", null, out mimeType, out encoding, out extension, out streamids, out warnings);
this.rvDuiXian.RefreshReport();
