少有人走的路资源列表：
业务逻辑BLL
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace student
{
public class StudentInstance
{
public DataChange onDataChange = null;
private List<StudentClass> StuList = new List<StudentClass>();
public List<StudentClass> stuAry
{
get { return StuList; }
}
public void AddStudent(StudentClass ParamStu)
{
if (StuList.Contains(ParamStu))
throw new Exception("student is exist!");
StuList.Add(ParamStu);
if (onDataChange != null)
onDataChange();
}
public void delStudent(StudentClass ParamStu)
{

if (onDataChange != null)
onDataChange();
}
public void loadAllData()
{
DataSourceManage ds = new DataSourceManage();
StuList = ds.getStudentData();
if (onDataChange != null)
{
onDataChange();
}
}
}
}控制器部分：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace student
{
class MVcontrol
{
StudentInstance stu;
public MVcontrol(StudentInstance ParamStu)
{
stu = ParamStu;
}
public void UpdateTree(TreeView tv)
{
tv.Nodes.Clear();
foreach (StudentClass m in stu.stuAry)
{
TreeNode node = new TreeNode();
node.Tag = m;
node.Text = m.Name;
tv.Nodes.Add(node);
}
}
public static void UpdateCbx(ComboBox cbx,Type type)
{
cbx.Items.Clear();
if (type.IsEnum)
{
string[] enumStr = Enum.GetNames(type);
foreach (string m in enumStr)
{
cbx.Items.Add(m);
}
}
}
}
}using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace student
{
public delegate void DataChange();
public delegate void ThreadDelegate(int js);
}using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
namespace student
{
class ThreadClass
{
public ThreadDelegate MainThreadUpdate = null;
public void ThreadFun()
{
int i = 0;
while (true)
{
++i;
MainThreadUpdate(i);
Thread.Sleep(2000);
}
}
}
