C#利用ReportViewer生成报表

/// <summary>  /// 设置报表  /// </summary>  private void SetReport()  {   //第一步：清除之前的数据   this.rptView.LocalReport.DataSources.Clear();   //第二步：指定报表路径   this.rptView.LocalReport.ReportPath = "Report2.rdlc";   //第三步：构造新的DataTable   DataTable dt = new DataTable("DataTable1");   dt.Columns.Add("Name");   dt.Columns.Add("Score");   dt.Columns.Add("Id");   dt.Rows.Add(new object[] { "语文", 80, "Y0001" });   dt.Rows.Add(new object[] { "数学", 75, "S0001" });   dt.Rows.Add(new object[] { "英文", 96, "E0001" });   //名称不能写错，和报表中的数据集名称一致   ReportDataSource rdsItem = new ReportDataSource("DataSet1", dt);   //此处可以有多个数据源   this.rptView.LocalReport.DataSources.Add(rdsItem);   //第四步：构造参数   List<ReportParameter> lstParameter = new List<ReportParameter>() {    new ReportParameter("Title",this.txtTitle.Text),    new ReportParameter("Id",this.txtId.Text),    new ReportParameter("Name",this.txtName.Text),    new ReportParameter("Age",this.txtAge.Text),    new ReportParameter("Sex",this.txtSex.Text),    new ReportParameter("Salary",this.txtSalary.Text),    new ReportParameter("Depart",this.txtDepart.Text)   };   this.rptView.LocalReport.SetParameters(lstParameter);   this.rptView.ZoomMode = ZoomMode.Percent;   this.rptView.ZoomPercent = 100;   //第五步：刷新报表   this.rptView.RefreshReport();  }
