Provides COM objects with version-independent access to the AppDomain::CreateInstanceFrom(String, String, array<Object>) method overload.

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

ObjectHandle^ CreateInstanceFrom(
	String^ assemblyFile, 
	String^ typeName, 
	array<Object^>^ activationAttributes
)

Parameters

assemblyFile
Type: System::String

The name, including the path, of a file that contains an assembly that defines the requested type. The assembly is loaded using the LoadFrom method.

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.

activationAttributes
Type: array<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.

Return Value

Type: System.Runtime.Remoting::ObjectHandle
An object that is a wrapper for the new instance, or nullptr if typeName is not found. The return value needs to be unwrapped to access the real object.

See the AppDomain::CreateInstanceFrom(String, String, array<Object>) method overload.

The activationAttributes parameter is related to client-activated objects; see Client Activation.
