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 type | Condition |
|---|---|
| assemblyName is a null reference (Nothing in Visual Basic). -or- typeName is a null reference (Nothing in Visual Basic). | |
| The caller cannot provide activation attributes for an object that does not inherit from MarshalByRefObject. | |
| Operations are attempted on an unloaded application domain. | |
| assemblyName was not found. | |
| typeName was not found in assemblyName. | |
| No parameterless public constructor was found. | |
| The caller does not have sufficient permission to call this constructor. | |
| assemblyName is not a valid assembly. | |
| An assembly or module was loaded twice with two different evidences. |
This is a convenience method that combines CreateInstanceFrom and ObjectHandle.Unwrap.

- 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.
