propertyInfo to extract the setter for. a fast getter. This method is more memory efficient than a dynamically compiled lambda, and about the same speed. This only works for reference types.

Given an object, adds each instance property with a public get method as a key and its associated value to a dictionary. If the object is already an instance, then a copy is returned.

The implementation of PropertyHelper will cache the property accessors per-type. This is faster when the the same type is used multiple times with ObjectToDictionary.

Gets the order value for determining the order of execution of filters. Filters execute in ascending numeric value of the property.

Filters are executed in an ordering determined by an ascending sort of the property.
