PHP to C# or VB Class - 25 lines or so

Simple, provide me a C# or VB Class which takes the input URL and gives me the download links [login to view URL] This is the PHP version, uses curl, so you will need to add some of your own text/string functions to get whats needed. Simple Class/Function, i provide the url, you kick out the urls, can be in the form of an array/list of custom objects you define
