AppDomain.CreateInstanceFromAndUnwrap Method (String, String, Boolean, BindingFlags, Binder, Object[], CultureInfo, Object[], Evidence)
Note: This API is now obsolete. The non-obsolete alternative is CreateInstanceFromAndUnwrap.
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. The UrlAttribute specifies the URL that is required to activate a remote object.
- securityAttributes
- Type: System.Security.Policy.Evidence
Information used to authorize creation of typeName.
| 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.
The activationAttributes parameter is related to client-activated objects; see Client Activation.

- 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.
