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
