How can I call a Matlab script from VB.net?

I've written a Matlab script which it calls several functions within itself, and now I need to run it from VB.net. The Matlab script has no input from VB, but it has an image output and a number from the workspace. After watching this youtube video, and reading this page, I wrote the following code within VB.net: (In this code main.m is the name of Matlab script)

Public Class Form1
    Dim MatLab As Object
    Dim Result As String
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        MatLab = CreateObject("Matlab.Application")
        Result = MatLab.Execute("cd D:\\main.m\")

    End Sub
End Class

Also, I tried to use these pages (link 1, link 2), but they returned errors.

cd stands for Change Directory. If you call cd D:\main.m\ you're trying to navigate to a directory called main.m (which does not exist).

You have to do this in two steps: Change the directory first, then execute the file.

'Change directory to "D:\".
Result = MatLab.Execute("cd D:\")

'Execute "main.m".
Result = MatLab.Execute("main")
