Public Structure MyStruct
    Public Id As Integer
    Public Name As String

    Public Sub New(id As Integer, name As String)
        Me.Id = id
        Me.Name = name
    End Sub
End Structure

Public Class Program
    Public Shared Sub Main()
        Dim list As List(Of MyStruct) = New List(Of MyStruct)()

        list.Add(New MyStruct(1, "aaa"))
        list.Add(New MyStruct(2, "bbb"))
        list.Add(New MyStruct(3, "ccc"))
        list.Add(New MyStruct(4, "ddd"))

        ' Convert List to an array of structures
        Dim structArray As MyStruct() = list.ToArray()

        For Each item In structArray
            Console.WriteLine($"Id: {item.Id}, Name: {item.Name}")

    End Sub

' Id: 1, Name: aaa
' Id: 2, Name: bbb
' Id: 3, Name: ccc
