C#制作RDLC报表

报表以前我只做过水晶报表，但是最近发现家里的VS上面居然没有水晶报表，发现水晶报表现在貌似已经不能完全免费的使用了，为了保险起见，就用了VS自带的RDLC报表，用完感觉其实也是够用的嘛~

建立一RDLC报表的过程主要是：

1、新建一个windows窗口，拖一个Reportview控件在上面，用来显示报表

2、新建一个类，构成数据源：

需要哪些字段，就在类中添加哪些，比如简单的如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace land_useowner_db
{
    class FarmerReportClass    //农户数据源
    {
        public string farmerBM { get;set; }
        public string farmerMC { get; set; }
        public string farmerLXDH { get; set; }
        public string farmerZJLX { get; set; }
        public string farmerZJHM { get; set; }
        public string farmerCBFDZ { get; set; }
        public string farmerYZBM { get; set; }
        public string farmerCBFCYSL { get; set; }
    }
}

数据源字段设置好后就要添加到数据库中：》

选择新建好的数据源类：　　

数据源添加好了，接下来就是给数据源赋予值了

3、新建一个报表

查看代码：

 using System;
 using System.Collections.Generic;
 using System.ComponentModel;
 using System.Data;
 using System.Drawing;
 using System.Linq;
 using System.Text;
 using System.Windows.Forms;

 using System.Data.OleDb;
 using Microsoft.Reporting.WinForms;

 namespace land_useowner_db.统计报表
 {
     public partial class FarmerReport : Form
     {
         string strCBFBM;
         string strCBFMC;
         string filepath;
         public FarmerReport(string CBFBM,string CBFMC,string path)
         {
             this.strCBFBM = CBFBM;
             this.strCBFMC = CBFMC;
             this.filepath = path;
             InitializeComponent();
         }

         private void FarmerReport_Load(object sender, EventArgs e)
         {
             #region test
             //this.reportViewer1.LocalReport.ReportEmbeddedResource = "land_useowner_db.统计报表.Report1.rdlc";
             //Microsoft.Reporting.WinForms.ReportParameter rp = new Microsoft.Reporting.WinForms.ReportParameter("cbfbm", strCBFBM);
             //this.reportViewer1.LocalReport.SetParameters(new Microsoft.Reporting.WinForms.ReportParameter[] { rp });
             //this.reportViewer1.RefreshReport();

             //为报表浏览器指定报表文件

             //this.reportViewer1.LocalReport.ReportEmbeddedResource = "report.Report1.rdlc";

             //指定数据集,数据集名称后为表,不是DataSet类型的数据集
             #endregion 

             this.reportViewer1.LocalReport.DataSources.Clear();
             this.reportViewer1.LocalReport.DataSources.Add(new Microsoft.Reporting.WinForms.ReportDataSource("land_useowner_db_FarmerReportClass", GetList()));

             //显示报表
             this.reportViewer1.RefreshReport();
         }

             connct.ConnectionString = oleDB;
             //创建命令
             OleDbCommand command = new OleDbCommand(sql, connct);
             //执行命令
             OleDbDataAdapter dataAdapter = new OleDbDataAdapter(command);
             DataTable table = new DataTable();
             try
             {
                 connct.Open();

4、在新建好的报表中就可以通过拖动相应的控件等来设计报表，简单的说就是画报表，安装需求画好相应的报表内容，比如：
