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

Creates a new instance of the specified type defined in the specified assembly. Parameters specify a binder, binding flags, constructor arguments, culture-specific information used to interpret arguments, activation attributes, and authorization to create the type.

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

public ObjectHandle CreateInstance (
	string assemblyName,
	string typeName,
	bool ignoreCase,
	BindingFlags bindingAttr,
	Binder binder,
	Object[] args,
	CultureInfo culture,
	Object[] activationAttributes,
	Evidence securityAttributes
)
public final ObjectHandle CreateInstance (
	String assemblyName, 
	String typeName, 
	boolean ignoreCase, 
	BindingFlags bindingAttr, 
	Binder binder, 
	Object[] args, 
	CultureInfo culture, 
	Object[] activationAttributes, 
	Evidence securityAttributes
)
public final function CreateInstance (
	assemblyName : String, 
	typeName : String, 
	ignoreCase : boolean, 
	bindingAttr : BindingFlags, 
	binder : Binder, 
	args : Object[], 
	culture : CultureInfo, 
	activationAttributes : Object[], 
	securityAttributes : Evidence
) : ObjectHandle

Parameters

assemblyName

The display name of the assembly. See Assembly.FullName.

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 using 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

An object that is a wrapper for the new instance specified by typeName. The return value needs to be unwrapped to access the real object.

Exception typeCondition

AppDomainUnloadedException

Operations are attempted on an unloaded application domain.

ArgumentNullException

assemblyName or typeName is a null reference (Nothing in Visual Basic).

BadImageFormatException

assemblyName is not a valid assembly.

FileLoadException

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

FileNotFoundException

assemblyName was not found.

MethodAccessException

The caller does not have permission to call this constructor.

MissingMethodException

No matching constructor was found.

NotSupportedException

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

TypeLoadException

typename was not found in assemblyName.

This method calls the default constructor for typeName.

See AssemblyName for the format of assemblyName.

An attempt to call CreateInstance on a target application domain that is not the current application domain will result in a successful load of the assembly in the target application domain. Since an Assembly is not MarshalByRefObject, when this method attempts to return the Assembly for the loaded assembly to the current application domain, the common language runtime will try to load the assembly into the current application domain and the load might fail. The assembly that is loaded into the current application domain might be different from the assembly that was loaded first if the path settings for the two application domains are different.
