UriKind Enumeration

.NET Framework 4

Defines the kinds of Uris for the Uri.IsWellFormedUriString(String, UriKind) and several Uri.Uri methods.

Namespace: System
Assembly: System (in System.dll)

Copy

public enum UriKind

	Member name	Description
	RelativeOrAbsolute	The kind of the Uri is indeterminate.
	Absolute	The Uri is an absolute Uri.
	Relative	The Uri is a relative Uri.

Absolute URIs are characterized by a complete reference to the resource (example: http://www.contoso.com/index.html), while a relative Uri depends on a previously defined base URI (example: /index.html).
