如何利用VB编写高效的进销存管理系统源码？

Imports System.Collections.Generic
Public Class Product
    Public Property Name As String
    Public Property Quantity As Integer
    Public Property Price As Double
End Class
Public Class Inventory
    Private products As New List(Of Product)()
    Public Sub AddProduct(ByVal product As Product)
        products.Add(product)
    End Sub
    Public Function GetProduct(ByVal name As String) As Product
        Return products.Find(Function(p) p.Name = name)
    End Function
    Public Sub SellProduct(ByVal name As String, ByVal quantity As Integer)
        Dim product = GetProduct(name)
        If product IsNot Nothing AndAlso product.Quantity >= quantity Then
            product.Quantity = quantity
        Else
            Console.WriteLine("库存不足或商品不存在")
        End If
    End Sub
    Public Function GetInventory() As List(Of Product)
        Return products
    End Function
End Class
Sub Main()
    Dim inventory As New Inventory()
    ' 添加商品
    Dim product1 As New Product With {.Name = "商品1", .Quantity = 10, .Price = 50.0}
    Dim product2 As New Product With {.Name = "商品2", .Quantity = 20, .Price = 100.0}
    inventory.AddProduct(product1)
    inventory.AddProduct(product2)
    ' 销售商品
    inventory.SellProduct("商品1", 3)
    ' 查看库存
    Dim products = inventory.GetInventory()
    For Each product In products
        Console.WriteLine($"商品名称： {product.Name}, 库存数量： {product.Quantity}, 价格： {product.Price}")
    Next
End Sub

这个示例中，我们定义了一个Product类来表示商品，包含名称、数量和价格属性，我们创建了一个Inventory类来管理商品的库存，包括添加商品、获取商品、销售商品和查看库存等功能，在Main方法中，我们创建了一个Inventory实例，并添加了一些商品，然后进行了销售操作，最后查看了库存情况。
