水晶报表填充.Net Objects数据源

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。

        {

        }
        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; }
    }
}
