Public Class Stocks
Public Property CodeProduct() As String
Public Property Barcode() As String
Public Property Colorcode() As String
Public Property Size() As String
Public Property QTY_STOCK() As Integer
End Class
>Solution :
You are declaring the stocks variable and using that variable in the expression that initialises it:
Dim stocks = New Stocks With { .QTY_STOCK = (stocks.QTY_STOCK - detail.Qty),
How can stocks.QTY_STOCK possibly have a value there when that’s the property you’re setting with that code? You haven’t bothered to explain what you’re actually trying to achieve with that code so we can’t tell you what it should be like, but it definitely shouldn’t be like that.
