從URL代碼VB.NET下載文件

Question

我想問一下，如何通過代碼vb.net從url下載文件？
例如：Example Link 下載文件之前，用戶必須輸入用戶名和密碼？我怎樣才能做到這一點？任何參考或鏈接？謝謝！

使用System.Net.WebClient.DownloadFile

Dim remoteUri As String = "http://belajar123.com/materi.zip" 
Dim fileName As String = "materi.zip" 
Dim pasword As String = "..." 
Dim username As String = "..." 

Using (var client = new WebClient()) 

    client.Credentials = New NetworkCredential(username, password) 
    client.DownloadFile(remoteUri, fileName) 
End Using
