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

 
obsoleteCodeEntityM:System.AppDomain.CreateInstanceFromAndUnwrap(System.String,System.String,System.Boolean,System.Reflection.BindingFlags,System.Reflection.Binder,System.Object[],System.Globalization.CultureInfo,System.Object[])Note: This API is now obsolete.

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

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

[ObsoleteAttribute("Methods which use evidence to sandbox are obsolete and will be removed in a future release of the .NET Framework. Please use an overload of CreateInstanceFromAndUnwrap which does not take an Evidence parameter. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information.")]
public object CreateInstanceFromAndUnwrap(
	string assemblyName,
	string typeName,
	bool ignoreCase,
	BindingFlags bindingAttr,
	Binder binder,
	object[] args,
	CultureInfo culture,
	object[] activationAttributes,
	Evidence securityAttributes
)

Parameters

assemblyName
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 that specifies the URL that is required to activate a remote object.

This parameter is related to client-activated objects. Client activation is a legacy technology that is retained for backward compatibility but is not recommended for new development. Distributed applications should instead use Windows Communication Foundation.

securityAttributes
Type: System.Security.Policy.Evidence

Information used to authorize creation of typeName.

Return Value

Type: System.Object

The requested object, or null if typeName is not found.

Exception Condition
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-

Version 2.0 or later of the common language runtime is currently loaded and assemblyName was compiled with a later version.

FileLoadException

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

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

For more information about this method, see the Activator.CreateInstanceFrom method.

FileIOPermissionAccess

for the ability to access the location of the assembly. Associated enumeration: FileIOPermissionAccess.PathDiscovery

FileIOPermissionAccess

for the ability to read the file containing the assembly manifest. Associated enumeration: FileIOPermissionAccess.Read

WebPermission

for the ability to access the location of the assembly if the assembly is not local.
