VB.NET中標準的實體類怎么寫的,請教VB高手指導

'代碼來源：代碼街codejie.net

'由于在vb.net里變量名不區(qū)分大小寫（StuName和stuname是一樣的），所以個別變量名需要修改

'在vb.net中,模塊級變量的命名原則是以m_開頭

Public Class Student

Private m_stuNo As String '學生號字段

Private m_stuName As String '學生姓名字段

Private m_stuAge As Integer '學生年齡字段

Private m_stuAddress As String '學生住址字段

'無參構造方法

Public Sub New()

End Sub

'有參構造方法

Public Sub New(ByVal stuNo As String, ByVal stuName As String, ByVal stuAge As Integer, ByVal stuAddress As String)

m_stuNo = stuNo

m_stuName = stuName

m_stuAge = stuAge

m_stuAddress = stuAddress

End Sub

'學生號屬性

Public Property StuNo() As String

Get

Return m_stuNo

End Get

Set(ByVal value As String)

m_stuNo = value

End Set

End Property

'學生姓名屬性

Public Property StuName() As String

Get

Return m_stuName

End Get

Set(ByVal value As String)

m_stuName = value

End Set

End Property

'學生年齡屬性

Public Property StuAge() As Integer

vb.net 集成開發(fā)的三種模式

設計模式：界面設計和代碼編輯

運行模式：運行應用程序

中斷模式：暫時中斷運行，調試程序

怎么利用VB.NET實現(xiàn)三維繪圖

數(shù)學上不是有斜二測畫法，算好坐標即可畫出

或者用AnyCAD的.Net圖形控件

也可以調用matlab 實現(xiàn)
