how to convert uri response of text/html chartset:iso-8859-1

Question

How can one convert the response recieved from Uri through WebClient into a human readable string. 

I have tried.   

1.  System.Text.Encoding
2. Convert.ToBase64String, Convert.FromBase64String

doesnot work as desired. it is either gibberish or empty string.

 

Thanks

Regards
