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：

  2 using System.Collections.Generic;
  3 using System.ComponentModel;
  4 using System.Data;
  5 using System.Drawing;

 21         {
 22             this.strCBFBM = CBFBM;
 23             this.strCBFMC = CBFMC;
 24             this.filepath = path;

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：
