Asp.net 自带报表的使用详解

1:新建報表所需的數據源DataSet.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data;

namespace ********
{
 public class DataSet
 {
 public DataTable CreatDataSet()
 {
 DataTable dt = new DataTable();
 dt.Columns.Add("A");
 dt.Columns.Add("B");
 dt.Columns.Add("C");
 return dt; }
 }
}

2：設計報表

報表設計這裡就不涉及了

3：把第一步新建的數據源加到報表裏面綁定

注意：這裡需要先引用 Interop.VBA.dll 才可以把新建的CS文件作為數據源導入

把數據源導入后綁定即可

4：直接把報表導出為PDF，Excel等格式

ReportViewer viewer = new ReportViewer();
 viewer.ProcessingMode = ProcessingMode.Local;
 viewer.LocalReport.ReportEmbeddedResource = "***.Page.Report.Report1.rdlc";
 ReportDataSource rds_1 = new ReportDataSource("DataSet1", dtReport);//DataSet1為報表裏面的數據源名稱
 viewer.LocalReport.DataSources.Add(rds_1); ReportParameter rp1 = new ReportParameter("參數1","參數1的值" );//給參數賦值
 ReportParameter rp2 = new ReportParameter("參數2","參數2的值" );
 viewer.LocalReport.SetParameters(new ReportParameter[] {rp1, rp2 });

 Warning[] warnings;
 string[] streamIds;
 string mimeType = string.Empty;
 string encoding = string.Empty;
 string extension = string.Empty;
 byte[] bytes = viewer.LocalReport.Render("Excel", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
 //Excel ,PDF ,Word 等格式 
 // Now that you have all the bytes representing the PDF report, buffer it and send it to the client.
 Response.Buffer = true;
 Response.Clear();
 Response.ContentType = mimeType;
 Response.AddHeader("content-disposition", "attachment; filename=1_" + DateTime.Now.ToString("yyyyMMddhhssmm") + "" + "." + extension);
 Response.BinaryWrite(bytes); // create the file
 Response.Flush(); // send it to the client to download

5:在頁面引用報表（rpResult為報表控件）

DataTable dt = new DataTable();//自己拼出數據源就可以
 ReportDataSource repDataSource = new ReportDataSource("DataSet1", dt); //*設置報表參數,并顯示
 this.rpResut.LocalReport.ReportEmbeddedResource = "***.Page.Report.Report1.rdlc"";
 this.rpResut.LocalReport.DataSources.Clear();
 this.rpResut.LocalReport.DataSources.Add(repDataSource);
 ReportParameter rp1 = new ReportParameter("參數1","參數1的值" );//給參數賦值
 ReportParameter rp2 = new ReportParameter("參數2","參數2的值" ); this.rpResut.LocalReport.SetParameters(new ReportParameter[] {rp1, rp2 });
 this.rpResut.DataBind();
 this.rpResut.LocalReport.Refresh();

至此，報表的產出和顯示都OK了，如果需要更深入的了解，請查看其它文章
