Activator.CreateInstance Method (Type, BindingFlags, Binder, Object[], CultureInfo)

Creates an instance of the specified type using the constructor that best matches the specified parameters.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public static Object CreateInstance (
	Type type,
	BindingFlags bindingAttr,
	Binder binder,
	Object[] args,
	CultureInfo culture
)
public static Object CreateInstance (
	Type type, 
	BindingFlags bindingAttr, 
	Binder binder, 
	Object[] args, 
	CultureInfo culture
)
public static function CreateInstance (
	type : Type, 
	bindingAttr : BindingFlags, 
	binder : Binder, 
	args : Object[], 
	culture : CultureInfo
) : Object

Parameters

type

The type of object to create.

bindingAttr

A combination of zero or more bit flags that affect the search for the type constructor. If bindingAttr is zero, a case-sensitive search for public constructors is conducted.

binder

An object that uses bindingAttr and args to seek and identify the type constructor. If binder is a null reference (Nothing in Visual Basic), the default binder is used.

args

An array of arguments that match in number, order, and type the parameters of the constructor to invoke. If args is an empty array or a null reference (Nothing in Visual Basic), the constructor that takes no parameters (the default constructor) is invoked.

culture

Culture-specific information that governs the coercion of args to the formal types declared for the type constructor. If culture is a null reference (Nothing in Visual Basic), the CultureInfo for the current thread is used.

Return Value

A reference to the newly created object.

Exception typeCondition

ArgumentNullException

type is a null reference (Nothing in Visual Basic).

ArgumentException

type is not a RuntimeType.

NotSupportedException

type cannot be a TypeBuilder.

-or-

Creation of TypedReference, ArgIterator, Void, and RuntimeArgumentHandle types, or arrays of those types, is not supported.

TargetInvocationException

The constructor being called throws an exception.

MethodAccessException

The caller does not have permission to call this constructor.

MemberAccessException

Cannot create an instance of an abstract class or this member was invoked with a late-binding mechanism.

InvalidComObjectException

The COM type was not obtained through GetTypeFromProgID or GetTypeFromCLSID.

MissingMethodException

No matching constructor was found.

COMException

type is a COM object but the class identifier used to obtain the type is invalid, or the identified class is not registered.

TypeLoadException

type is not a valid type.

The constructor to be invoked must be accessible and provide the most specific match with the specified argument list under the constraints of the specified binder and binding attributes.
