Shaping Purchase Data into a Manageable Format Using Dapper Library in C#
The provided solution uses the Dapper library to shape data from original tables. It creates classes for Invoice, Detail, and StockCard to hold related data. The code then loads data into these classes using Dapper’s Query method. To clarify, I will break down the solution into smaller steps: Step 1: Define classes Public Class Invoice Property Invono() As Integer Property Invodate() As Date Property Transaction() As String Property Remark() As String Property NameSC() As String End Class Public Class Detail Public Property InvoNo() As String Public Property No() As Integer Public Property CodeProduct() As String Public Property Info() As String Public Property Qty() As Integer End Class Public Class StockCard Public Property InvoNo As String Public Property InvoDate As Date Public Property Transaction As String Public Property No As Integer Public Property CodeProduct As String Public Property Info As String Public Property Remark As String Public Property NameSC As String Public Property [IN] As String Public Property [OUT] As String Public Property BALANCE As Integer End Class Step 2: Load data using Dapper
