ScriptFunction Class

.NET Framework 4

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Represents a prototype-based object that is defined by a constructor function. Most of the constructor function classes, such as DateConstructor, NumberConstructor, StringConstructor, and ObjectConstructor, inherit from this class. This class belongs to the objects and functions category.

	GetProperty(String, BindingFlags)	Gets a property that has the specified name. (Inherited from ScriptObject.)
	GetProperty(String, BindingFlags, Binder, Type, Type[], ParameterModifier[])	Gets a property that has the specified name by using the specified selection criteria. (Inherited from ScriptObject.)
	GetPrototypeForConstructedObject	Gets the prototype object for this constructor function.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Invoke	Invokes a method of the prototype-based object, passing in the specified arguments.
	InvokeMember	Invokes the specified member. (Overrides ScriptObject.InvokeMember(String, BindingFlags, Binder, Object, Object[], ParameterModifier[], CultureInfo, String[]).)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SetMemberValue2	Sets the value of a field that was dynamically added to the object and stored in field_table. (Inherited from JSObject.)
	ToString	Returns a string representation of the constructor function. (Overrides JSObject.ToString().)
