VB.NET 相当于 VB6 属性 Item.VB_UserMemId = 0

VB.NET是一种面向对象的编程语言，它是Visual Basic 6的继任者。VB.NET相当于VB6中的属性Item.VB_UserMemId = 0。在本文中，我们将探讨VB.NET的一些特点以及如何使用VB.NET编写代码。

Public Class MyClass
    Private _myProperty As String
    Public Property MyProperty As String
        Get
            Return _myProperty
        End Get
        Set(value As String)
            _myProperty = value
        End Set
    End Property
    Public Sub New()
        _myProperty = ""
    End Sub
    Default Public Property Item(index As Integer) As String
        Get
            Return _myProperty
        End Get
        Set(value As String)
            _myProperty = value
        End Set
    End Property
End Class
Module Module1
    Sub Main()
        Dim myObject As New MyClass()
        myObject.Item.VB_UserMemId = 0
        ' 设置属性Item.VB_UserMemId为0
        Console.WriteLine("Item.VB_UserMemId: {0}", myObject.Item.VB_UserMemId)
    End Sub
End Module

Module Module1
    Sub Main()
        Dim num1 As Integer
        Dim num2 As Integer
        Console.WriteLine("请输入第一个数：")
        num1 = Console.ReadLine()
        Console.WriteLine("请输入第二个数：")
        num2 = Console.ReadLine()
        Dim sum As Integer = num1 + num2
        Console.WriteLine("两个数的和为：{0}", sum)
    End Sub
End Module
