When overridden in a descendant class, gets the URI of the Internet resource associated with the request. When overridden in a descendant class, gets or sets the network proxy to use to access this Internet resource. When overridden in a descendant class, indicates whether to pre-authenticate the request. When overridden in a descendant class, gets or sets the protocol method to use in this request. Gets or sets the impersonation level for the current request. When overridden in a descendant class, gets or sets the collection of header name/value pairs associated with the request. Gets or sets the default cache policy for this request. When overridden in a descendant class, gets or sets the network credentials used for authenticating the request with the Internet resource. When overridden in a descendant class, gets the factory object derived from the IWebRequestCreate class used to create the WebRequest instantiated for making the request to the specified URI. For more information about default values and exceptions, see the documentation for the descendant classes, such as HttpWebRequest and FileWebRequest. When Status is WebExceptionStatus.ProtocolError, the Response property contains the WebResponse received from the Internet resource.īecause the WebRequest class is an abstract class, the actual behavior of WebRequest instances at run time is determined by the descendant class returned by Create method. The Status property is one of the WebExceptionStatus values that indicates the source of the error. The WebRequest class throws a WebException when errors occur while accessing an Internet resource. WebRequest descendants are typically registered to handle a specific protocol, such as HTTP or FTP, but can be registered to handle a request to a specific server or path on a server. The URI determines the proper descendant class to create from a list of WebRequest descendants registered for the application. Requests are sent from an application to a particular URI, such as a Web page on a server. An application that uses the request/response model can request data from the Internet in a protocol-agnostic manner, in which the application works with instances of the WebRequest class while protocol-specific descendant classes carry out the details of the request. NET's request/response model for accessing data from the Internet. WebRequest is the abstract base class for.
