System.Net.WebRequest is an abstract base class that encapsulates a web request, and is protocol agnostic. For each common protocol, the .NET Framework includes a class that derives from System.Net.WebRequest and extends it with protocol-specific state and behavior, including:
PackWebRequest: URIs that use the pack:// scheme to request application data files (see Windows Presentation Foundation Application Resource, Content, and Data Files).
HttpWebRequest: URIs that use the http:// scheme to request files from Web servers.
FtpWebRequest: URIs that use the ftp:// scheme to request files from FTP servers.
FileWebRequest: URIs that use the file:// scheme to request local files.
Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003
The .NET Framework and .NET Compact Framework do not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
