Creates a new instance of the specified type defined in the specified assembly file.

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

public Object CreateInstanceFromAndUnwrap (
	string assemblyName,
	string typeName,
	bool ignoreCase,
	BindingFlags bindingAttr,
	Binder binder,
	Object[] args,
	CultureInfo culture,
	Object[] activationAttributes,
	Evidence securityAttributes
)
public Object CreateInstanceFromAndUnwrap (
	String assemblyName, 
	String typeName, 
	boolean ignoreCase, 
	BindingFlags bindingAttr, 
	Binder binder, 
	Object[] args, 
	CultureInfo culture, 
	Object[] activationAttributes, 
	Evidence securityAttributes
)
public function CreateInstanceFromAndUnwrap (
	assemblyName : String, 
	typeName : String, 
	ignoreCase : boolean, 
	bindingAttr : BindingFlags, 
	binder : Binder, 
	args : Object[], 
	culture : CultureInfo, 
	activationAttributes : Object[], 
	securityAttributes : Evidence
) : Object

Parameters

assemblyName

The file name and path of the assembly that defines the requested type.

typeName

The fully qualified name of the requested type, including the namespace but not the assembly, as returned by the Type.FullName property.

ignoreCase

A Boolean value specifying whether to perform a case-sensitive search or not.

bindingAttr

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

binder

An object that enables the binding, coercion of argument types, invocation of members, and retrieval of MemberInfo objects through reflection. If binder is null, the default binder is used.

args

The arguments to pass to the constructor. This array of arguments must match in number, order, and type the parameters of the constructor to invoke. If the default constructor is preferred, args must be an empty array or null.

culture

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

activationAttributes

One or more attributes that can participate in activation.

securityAttributes

Information used to authorize creation of typeName.

Return Value

The requested object, or a null reference (Nothing in Visual Basic) if typeName is not found.

Exception typeCondition

ArgumentNullException

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

-or-

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

NotSupportedException

The caller cannot provide activation attributes for an object that does not inherit from MarshalByRefObject.

AppDomainUnloadedException

Operations are attempted on an unloaded application domain.

FileNotFoundException

assemblyName was not found.

TypeLoadException

typeName was not found in assemblyName.

MissingMethodException

No parameterless public constructor was found.

MethodAccessException

The caller does not have sufficient permission to call this constructor.

BadImageFormatException

assemblyName is not a valid assembly.

FileLoadException

An assembly or module was loaded twice with two different evidences.

This is a convenience method that combines CreateInstanceFrom and ObjectHandle.Unwrap.
