The length of stringToEscape exceeds 32766 characters.

By default, the EscapeDataString method converts all characters except for RFC 2396 unreserved characters to their hexadecimal representation. If International Resource Identifiers (IRIs) or Internationalized Domain Name (IDN) parsing is enabled, the EscapeDataString 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.
