Reporting Services的简单使用

最近公司的功能需要使用报表，用的是微软自带的报表，谈一谈我们的做法，希望可以给想学习的人一些指导

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;

        }

    }

}

指定所需要綁定的Table的列，返回dataTable 類,CreatDataSet方法名稱隨便起，也可以在一個類裏面定義多個方法（不同數據源）

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();

6：子報表的使用

        void LocalReport_SubreportProcessing(object sender, SubreportProcessingEventArgs e)

        {

            string MasterID = e.Parameters["MasterID"].Values[];

            DataRow[] drs_Main = dtSubReport.Select("MasterID = '" + MasterID + "'");

            DataTable dtReport = drs_Main.CopyToDataTable();

            e.DataSources.Add(new ReportDataSource("DataSetMain", dtReport));

        }

7：調用

ReportViewer viewer = new ReportViewer();

            viewer.LocalReport.SubreportProcessing += new SubreportProcessingEventHandler(LocalReport_SubreportProcessing);

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
