Remarks

Use the EscapeUriString method to prepare an unescaped URI string to be a parameter to the Uri constructor.

By default, the EscapeUriString method converts all characters, except RFC 2396 unreserved characters, to their hexadecimal representation. If International Resource Identifiers (IRIs) or Internationalized Domain Name (IDN) parsing is enabled, the EscapeUriString method converts all characters, except for RFC 3986 unreserved characters, to their hexadecimal representation. All Unicode characters are converted to UTF-8 format before being escaped.

This method assumes that stringToEscape has no escape sequences in it.

By default, the string is escaped according to RFC 2396. If International Resource Identifiers (IRIs) or Internationalized Domain Name (IDN) parsing is enabled, the string is escaped according to RFC 3986 and RFC 3987. See these RFCs for a definition of reserved and unreserved characters.

For more information on IRI support, see the Remarks section for the Uri class.
