Public Overridable Function CreateInstance (provider As IServiceProvider, objectType As Type, argTypes As Type(), args As Object()) As Object

Parameters

provider: IServiceProvider

An optional service provider.

objectType: Type

The type of object to create. This parameter is never null.

argTypes: Type[]

An optional array of types that represent the parameter types to be passed to the object's constructor. This array can be null or of zero length.

args: Object[]

An optional array of parameter values to pass to the object's constructor.

Returns

Object

The substitute Object.

Attributes: UnsupportedOSPlatformAttribute

Remarks

The IServiceProvider specified by the provider parameter is passed in by the TypeDescriptor.CreateInstance method of the TypeDescriptor class. If provider is not null, the service provider can be used by the type description provider to obtain additional context about the creation call.

The CreateInstance method is virtual and, by default, returns the result of the Activator.CreateInstance method if parent is null. If parent is not null, this method will invoke the CreateInstance method of the parent provider.

Notes to Inheritors

If the derived class is not interested in providing a substitute instance, it should just call the base implementation.
