Crystal Reports（水晶报表）是一款商务智能（BI）软件，主要用于设计及产生报表。是业内最专业、功能最强的报表系统。
查看网络资料及课本图书，鲜有介绍通过.NET Objects作为数据源填充水晶报表的示例。本文将通过两个简单的示例演示水晶报表填充.Net Objects数据源的过程。
示例一：打印学生信息（一个.NET Objects数据源的填充）
示例效果：
Student.cs
using System;
using System.Collections.Generic;
using System.Web;
namespace CrystalReportsDemo
{
public class Student
{
public Student(string studentNo,string studentName,string sex,int age)
{
this.StudentNo = studentNo;
this.StudentName = studentName;
this.Sex = sex;
this.Age = age;
}
public string StudentNo
{ set; get; }
public string StudentName
{ set; get; }
public string Sex
{ get; private set; }
public int Age
{ get; private set; }
}
}
将其编译后，即可通过数据库专家将其作为数据源导入到字段资源管理器。
绘制报表样式并插入数据库字段：
在Default.aspx页面拖入CrystalReportViewer控件：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="CrystalReportsDemo._Default" %>
<%@ Register assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" namespace="CrystalDecisions.Web" tagprefix="CR" %>

</head>
<body>
<form id="form1" runat="server">
<div>
<CR:CrystalReportViewer ID="crvReport" runat="server" AutoDataBind="true" />
</div>
</form>
</body>
</html>
Default.aspx.cs
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace CrystalReportsDemo
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
FillReport();
}
private void FillReport()
{
List<Student> studentList = new List<Student>();
studentList.Add(new Student("200901001", "学生一", "男", 23));
studentList.Add(new Student("200901002", "学生二", "男", 24));
studentList.Add(new Student("200901003", "学生三", "女", 22));
studentList.Add(new Student("200901004", "学生四", "男", 23));
studentList.Add(new Student("200901005", "学生五", "女", 25));
studentList.Add(new Student("200901006", "学生六", "男", 23));
CrStudents studentsReport = new CrStudents();
studentsReport.SetDataSource(studentList);
crvReport.ReportSource = studentsReport;
}
}
}
示例二：打印学生成绩（多个.NET Objects数据源的填充）
示例效果：
Subject.cs
using System;
using System.Collections.Generic;
using System.Web;
namespace CrystalReportsDemo
{
public class Subject
{
public Subject(string subjectName,string subjectType,double result,string comment)
{
this.SubjectName = subjectName;
this.SubjectType = subjectType;
this.Result = result;
this.Comment = comment;
}
public string SubjectName
{ set; get; }
public string SubjectType
{ set; get; }
public double Result
{ set; get; }
public string Comment
{ set; get; }
}
}
主报表：（CrSupReport.rpt）
子报表：（CrSubReport.rpt）
Default2.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default2.aspx.cs" Inherits="CrystalReportsDemo.Default2" %>
