Download one file in ASP.net VB

Good day all

I'm really sorry if this question has been asked before, I have searched a lot without success. I want to download one file from my own account using ASP.net, but using VB (not C#). I have downloaded the V2 API package 

 PM> Install-Package Dropbox.Api

I have tried without using the above SDK using this code. Although a file is created on my computer its full of junk.

    Protected Sub Button5_Click(sender As Object, e As EventArgs) Handles Button5.Click


Dim UrlPath As String = "https://www.dropbox.com/s/quswjzadmomb6xz/Linux.txt?dl=0" ' make sure you get the download path of the file in this format
        Dim DownloadToThisFilename As String = "C:\test\FileName.txt"  ' filename for the file to be downloaded to
        Try
            Using Client As New System.Net.WebClient()
                Client.DownloadFile(UrlPath, DownloadToThisFilename)
            End Using
        Catch

            MsgBox("Issues")


        End Try



    End Sub

Two solutions I think are possible and I would be happy with either

1. A VB solution that is similar to the above  

or

2. A solution that does use the SDK, but once again written in VB

Any help very much appreciated

PS - its an Excel file I want to download if that makes any difference
