This instance represents a relative URI, and this property is valid only for absolute URIs.
Remarks
The query property contains any query information included in the URI. query information is separated from the path information by a question mark (?) and continues to the end of the URI. The query information returned includes the leading question mark.
The query information is escaped according to RFC 2396 by default. If International Resource Identifiers (IRIs) or Internationalized Domain Name (IDN) parsing is enabled, the query information is escaped according to RFC 3986 and RFC 3987.
For more information on URI support, see the Remarks section for the xtd::uri class.
