sealed class

This class is a simple HTTP User-Agent. Use DownloadData( ) to fetch a document as an array of bytes. The DownloadFile( ) method fetches a document and stores it in a file. You can upload data to a URI using UploadFile( ) or UploadData( ) (which uploads the contents of a byte array).

Before connecting to a URI, invoke the Add( ) method of the QueryString or Headers properties to add a key/value pair to the HTTP query string or HTTP request headers. Set the credentials property to authenticate the WebClient to the remote server, if necessary.
