Methods

	Name	Description
	Equals(Object)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)
	TryUpdateModel<'TModel>('TModel)	Updates the specified model instance using values from a value provider.
	TryUpdateModel<'TModel>('TModel, IValueProvider)	Updates the specified model instance using values from the specified value provider.
	UpdateModel<'TModel>('TModel)	Updates the specified model instance using values from a value provider.
	UpdateModel<'TModel>('TModel, IValueProvider)	Updates the specified model instance using values from the specified value provider.

For example, a custom class can define the methods referred to by the SelectMethod, UpdateMethod, DeleteMethod, and InsertMethod properties for data binding, and those methods can have a parameter of this type and use it to invoke the UpdateModel<'TModel> method. Alternatively, instead of a method parameter, the Current property can be used within a method to invoke the UpdateModel<'TModel> method.
