C# in a Nutshell

Name

WebClient

Synopsis

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.
