public function Uri (
	uriString : String, 
	uriKind : UriKind



A string that identifies the resource to be represented by the Uri instance.


Specifies whether the URI string is a relative URI, absolute URI, or is indeterminate.

Exception typeCondition


uriString contains a relative URI and uriKind is Absolute.


uriString contains an absolute URI and uriKind is Relative.

Relative and absolute URIs have different restrictions on their format. For example, a relative URI does not require a scheme or an authority. The value you specify in uriKind must match the type of URI passed in uriString. However, if RelativeOrAbsolute is specified, the URI string can be relative or absolute.
