Changing a field length and its values in VB.NET

[pourkascheff]

Hi all.
Consider a field of variables like below:

    Private Sendcmd() As Byte

    Public Sub New()
        InitializeComponent()
    End Sub

There is a NumericUpDown control (called SendLenght) which determines Sendcmd length i.e. from 1 to 64.
By clicking a button, filling Sendcmd with NumericUpDown values from 1 to current value of SendLenght. (There are 64 NumericUpDown maximum)

How can I do such thing in VB.NET?
I tried for loop as shown below but I suspected an array or collection making is required.

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim NumericUpDown As NumericUpDown() = {NumericUpDown1, NumericUpDown2, NumericUpDown3, NumericUpDown4, NumericUpDown5, NumericUpDown6, NumericUpDown7, NumericUpDown8, NumericUpDown9, NumericUpDown10, NumericUpDown11, NumericUpDown12, NumericUpDown13, NumericUpDown14, NumericUpDown15, NumericUpDown16, NumericUpDown17, NumericUpDown18, NumericUpDown19, NumericUpDown20, NumericUpDown21, NumericUpDown22, NumericUpDown23, NumericUpDown24, NumericUpDown25, NumericUpDown26, NumericUpDown27, NumericUpDown28, NumericUpDown29, NumericUpDown30, NumericUpDown31, NumericUpDown32, NumericUpDown33, NumericUpDown34, NumericUpDown35, NumericUpDown36, NumericUpDown37, NumericUpDown38, NumericUpDown39, NumericUpDown40, NumericUpDown41, NumericUpDown42, NumericUpDown43, NumericUpDown44, NumericUpDown45, NumericUpDown46, NumericUpDown47, NumericUpDown48, NumericUpDown49, NumericUpDown50, NumericUpDown51, NumericUpDown52, NumericUpDown53, NumericUpDown54, NumericUpDown55, NumericUpDown56, NumericUpDown57, NumericUpDown58, NumericUpDown59, NumericUpDown60, NumericUpDown61, NumericUpDown62, NumericUpDown63, NumericUpDown64}
        For i As Decimal = 1 To SendLenght.Value
            Sendcmd(i - 1)=Sendcmd(i - 1) {NumericUpDown i - 1}   '<-- End of statement expected error to this line
        Next
    End Sub

Thanks in advanced.

/UPDATE/
Expected results:

For SendLenght.Value = 1

Sendcmd(1) = {NumericUpDown1.Value}

For SendLenght.Value = 2

Sendcmd(2) = {NumericUpDown1.Value, NumericUpDown2.Value}

For SendLenght.Value = 10

Sendcmd(10) = {NumericUpDown1.Value, NumericUpDown2.Value, NumericUpDown3.Value, NumericUpDown4.Value, NumericUpDown5.Value, NumericUpDown6.Value, NumericUpDown7.Value, NumericUpDown8.Value, NumericUpDown9.Value, NumericUpDown10.Value}
