A bitwise combination of the enumeration values that specify options for the named property.

Attributes

Exceptions

name is null.

Remarks

The options parameter is specifically used to indicate the following:

  • Whether the property is built-in, or custom.

  • Whether the property should be persisted with the key.

These options must match the value that the property was set with, or the property will not be found.

This method operates correctly even if the property is set to false or zero.
