Activator.CreateInstanceFrom Method (String, String, Boolean, BindingFlags, Binder, Object, CultureInfo, Object, Evidence)
Assembly: mscorlib (in mscorlib.dll)
public static ObjectHandle CreateInstanceFrom ( string assemblyFile, string typeName, bool ignoreCase, BindingFlags bindingAttr, Binder binder, Object args, CultureInfo culture, Object activationAttributes, Evidence securityInfo )
public static ObjectHandle CreateInstanceFrom ( String assemblyFile, String typeName, boolean ignoreCase, BindingFlags bindingAttr, Binder binder, Object args, CultureInfo culture, Object activationAttributes, Evidence securityInfo )
public static function CreateInstanceFrom ( assemblyFile : String, typeName : String, ignoreCase : boolean, bindingAttr : BindingFlags, binder : Binder, args : Object, culture : CultureInfo, activationAttributes : Object, securityInfo : Evidence ) : ObjectHandle
The name of a file that contains an assembly where the type named typeName is sought.
The name of the preferred type.
true to specify the search for typeName is not case-sensitive; false to specify the search is case-sensitive.
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.
An object that uses bindingAttr and args to seek and identify the typeName constructor. If binder is a null reference (Nothing in Visual Basic), the default binder is used.
An array of arguments that match in number, order, and type the parameters of the constructor to invoke. If args is an empty array or a null reference (Nothing in Visual Basic), the constructor that takes no parameters (the default constructor) is invoked.
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.
An array of one or more attributes that can participate in activation.
Information used to make security policy decisions and grant code permissions.
Return ValueA handle that must be unwrapped to access the newly created instance.
typeName is a null reference (Nothing in Visual Basic).
No matching constructor was found.
typename was not found in assemblyFile.
assemblyFile was not found.
The caller does not have permission to call this constructor.
Cannot create an instance of an abstract class or this member was invoked with a late-binding mechanism.
The constructor, which was invoked through reflection, threw an exception.
The caller does have the required FileIOPermission.
activationAttributes is not an empty array and the type being created does not derive from MarshalByRefObject.
- SecurityPermission for the ability to call unmanaged code when creating an instance of a delegate. Associated enumeration: SecurityPermissionFlag/UnmanagedCode
- ReflectionPermission for the ability to invoke operations on all type members. Associated enumeration: ReflectionPermissionFlag/MemberAccess
- FileIOPermission for the ability to search directory paths and read their contents. Associated enumerations: FileIOPermissionAccess/PathDiscovery and Read
