今天无聊中弄了个小东西,熟悉一下对listview和treeview的用法。代码如下:

 public partial class Form1 : Form
    {
        private School school;
        public Form1()
        {
            InitializeComponent();
            Office o1 = new Office("计算机基础","王军","杨晓勇","何平","姜涛");
            Office o2 = new Office("软件工程", "马建国", "陈军", "刘晓燕");
            Office o3 = new Office("信息安全", "冯尧", "李建军", "张涛");
            Department d1=new Department("计算机",o1,o2,o3);
            Office o4 = new Office("自动控制", "吴自力", "陈锋", "薛小龙");
            Office o5 = new Office("工业设计", "吴淑华", "方坤", "何丽", "蔡聪");
            Department d2=new Department("机电工程",o4,o5);
            Office o6 = new Office("信息管理", "赵民", "盛晓楠", "徐小平");
            Office o7 = new Office("工商管理", "张敏", "李玲", "吕倩", "高健");
            Department d3=new Department("经济管理",o6,o7);
            school = new School("科大", d1, d2, d3);             TreeNode root = treeView1.Nodes.Add(school.ToString());
            foreach(Department d in school.departments )
            {
                TreeNode node = root.Nodes.Add(d.ToString());
                foreach (Office o in d.offices)
                {
                    node.Nodes.Add(o.ToString());
                }
            }
            listView1.Columns.Add("姓名");
            listView1.Columns.Add("电话");
            listView1.Columns.Add("电子邮件");         }         private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
        {
            listView1.Items.Clear();
            if (e.Node.Level == 0)
            {
                foreach (Department d in school.departments)
                {
                    listView1.Items.Add(d.ToString(),0);
                }
            }
            else if (e.Node.Level == 1)
            {
                foreach (Office o in school.departments[e.Node.Index].offices)
                {
                    listView1.Items.Add(o.ToString(), 1);
                }
            }
            else if (e.Node.Level == 2)
            {
                foreach (string s in school.departments[e.Node.Parent.Index].offices[e.Node.Index].teachers)
                {
                    listView1.Items.Add(s.ToString(), 2);
                }
            }
        }
    }     public class School
    {
        public School(string name, params Department[] departments)
        {
            this.Name = name;
            this.departments = new List<Department>(departments);
        }
        public string Name { get; set; }
        public List<Department> departments { get; set; }
        public override string ToString()
        {
            return Name;
        }
    }     public class Department
    {
        public string Name { get; set; }
        public List<Office> offices { get; set; }
        public Department(string name, params Office[] offices)
        {
            this.Name = name;
            this.offices = new List<Office>(offices);
        }
        public override string ToString()
        {
            return Name + "系";
        }
    }     public class Office
    {
        public string Name { get; set; }
        public List<string> teachers { get; set; }
        public Office(string name, params string[] teachers)
        {
            this.Name = name;
            this.teachers = new List<string>(teachers);
        }
        public override string ToString()
        {
            return Name + "教研室";
        }
    }
