注释

The host log provider is a class that provides the methods and properties that are common to all of the log providers. Regardless of which log provider is in use, this class allows you to perform all tasks associated with logging. The LogProvider class is the object you use when programmatically adding log providers to a package. It is a generic host log provider that hosts an underlying log provider. The hosted log provider is accessible using the InnerObject. If you want to create a custom log provider, use the LogProviderBase class.
