Parameters

requestUri
A Uri containing the URI of the requested resource.

Return Value

A WebRequest descendant for the specified URI scheme.

Exceptions

Exception Type Condition
NotSupportedException The request scheme specified in requestUri is not registered.
ArgumentNullException requestUri is a null reference (Nothing in Visual Basic).
SecurityException The caller does not have permission to connect to the requested URI or a URI that the request is redirected to.

Remarks

The CreateDefault method returns a WebRequest descendant instance based on only the scheme portion of a URI.

For example, when a URI beginning with http:// is passed in requestUri, an HttpWebRequest is returned by CreateDefault. If a URI beginning with file:// is passed instead, the CreateDefault method will return a FileWebRequest.
