Download one file in ASP.net VB

Question

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:	est\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

1. If you have a shared link to a file, you can download it directly. Note that the link you shared in your code though points to the HTML preview page for the file, not the file data itself, so your code won't work as is.

You can modify these links to point to the file data though, as documented here:

2 Alternatively, you can use the official Dropbox API v2 .NET SDK:

https://github.com/dropbox/dropbox-sdk-dotnet

With that, you can use the GetSharedLinkFile method to download a file from a shared link:
