AppDomain.CreateInstanceFromAndUnwrap Method (String, String, Boolean, BindingFlags, Binder, Object[], CultureInfo, Object[])

Creates a new instance of the specified type defined in the specified assembly file, specifying whether the case of the type name is ignored; the binding attributes and the binder that are used to select the type to be created; the arguments of the constructor; the culture; and the activation attributes.

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

public Object CreateInstanceFromAndUnwrap(
	string assemblyFile,
	string typeName,
	bool ignoreCase,
	BindingFlags bindingAttr,
	Binder binder,
	Object[] args,
	CultureInfo culture,
	Object[] activationAttributes
)

Parameters

assemblyFile
Type: System.String
The file name and path of the assembly that defines the requested type.
typeName
Type: System.String
The fully qualified name of the requested type, including the namespace but not the assembly, as returned by the Type.FullName property.
ignoreCase
Type: System.Boolean
A Boolean value specifying whether to perform a case-sensitive search or not.
bindingAttr
Type: System.Reflection.BindingFlags
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
Type: System.Reflection.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
Type: System.Object[]
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
Type: System.Globalization.CultureInfo
Culture-specific information that governs the coercion of args to the formal types declared for the typeName constructor. If culture is null, the CultureInfo for the current thread is used.
activationAttributes
Type: System.Object[]
An array of one or more attributes that can participate in activation. Typically, an array that contains a single UrlAttribute object. The UrlAttribute specifies the URL that is required to activate a remote object.

Return Value

Type: System.Object
The requested object, or null if typeName is not found.

ExceptionCondition
ArgumentNullException

assemblyName is null.

-or-

typeName is null.

NotSupportedException

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

AppDomainUnloadedException

The operation is attempted on an unloaded application domain.

FileNotFoundException

assemblyName was not found.

TypeLoadException

typeName was not found in assemblyName.

MissingMethodException

No matching public constructor was found.

MethodAccessException

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

BadImageFormatException

assemblyName is not a valid assembly.

-or-

assemblyName was compiled with a later version of the common language runtime that the version that is currently loaded.

FileLoadException

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

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

The activationAttributes parameter is related to client-activated objects; see Client Activation.
