屬性

	名稱	說明
	ConfigString	Gets or sets the connection and configuration information for the specific log provider.
	CreationName	Returns the string used by the runtime to create an instance of the LogProvider object. This property is read-only.
	DelayValidation	Gets or sets a Boolean that specifies whether a call to Validate for the log provider is delayed until package execution.
	Description	Gets or sets the description of the LogProvider object.
	HostType	Gets an enumeration that describes the type of host that the log provider is being used by. This property is read-only
	ID	Gets the ID of the LogProvider. This property is read-only.
	InnerObject	Returns the specific log provider that is being hosted by the LogProvider object.
	Name	Gets or sets a the name of the LogProvider object, such as "SSIS log provider for Text files". This string is the text that shows in the Configure SSIS Logs (Providers and Logs Tab) dialog box in the Provider type drop-down menu.
	Properties	Returns a DtsProperties collection, which contains a collection of DtsProperty objects.

	CloseLog	Closes the log.
	Dispose	Releases the resources used by the log provider.
	Equals	Determines whether two object instances are equal. (繼承自 DtsObject。)
	Finalize	(繼承自 Object。)
	GetExpression	Returns a String that contains the expression for the specified property. Null means no expression is assigned.
	GetHashCode	Returns the hash code for this instance. (繼承自 DtsObject。)
	GetPackagePath	Returns a String that contains the relative path to the package location.
	GetType	(繼承自 Object。)

	MemberwiseClone	(繼承自 Object。)
	OpenLog	Opens the log.
	SaveToXML	This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method.
	SetExpression	Assigns the specified expression to the property. Specify nullNothingnullptrunitnull 參考 (在 Visual Basic 中為 Nothing) to remove an existing expression from the property.

備註

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.
