Properties

	Name	Description
	AllowReadOnlyTasks	Gets or sets a value indicating whether to allow tasks from later OS versions with new properties to be retrieved as read only tasks.
	AllTasks	Gets a IEnumeratorT which enumerates all the tasks in all folders.
	CanRaiseEvents	Gets a value indicating whether the component can raise an event. (Overrides ComponentCanRaiseEvents)
	Connected	Gets a Boolean value that indicates if you are connected to the Task Scheduler service.
	ConnectedDomain	Obsolete. Gets the name of the domain to which the TargetServer computer is connected.
	ConnectedUser	Obsolete. Gets the name of the user that is connected to the Task Scheduler service.
	Container	Gets the IContainer that contains the Component. (Inherited from Component)
	DesignMode	Gets a value that indicates whether the Component is currently in design mode. (Inherited from Component)
	Events	Gets the list of event handlers that are attached to this Component. (Inherited from Component)
	HighestSupportedVersion	Gets the highest version of Task Scheduler that a computer supports.
	Instance	Gets a local instance of the TaskService using the current user's credentials.
	LibraryVersion	Gets the library version. This is the highest version supported by the local library. Tasks cannot be created using any compatibility level higher than this version.
	RootFolder	Gets the root ("\") folder. For Task Scheduler 1.0, this is the only folder.
	Site	Gets or sets the ISite of the Component. (Inherited from Component)
	TargetServer	Gets or sets the name of the computer that is running the Task Scheduler service that the user is connected to.
	Token	Gets the connection token for this TaskService instance. This token is thread safe and can be used to create new TaskService instances on other threads using the CreateFromToken(TaskServiceConnectionToken) static method.
	UserAccountDomain	Gets or sets the user account domain to be used when connecting to the TargetServer.
	UserName	Gets or sets the user name to be used when connecting to the TargetServer.
	UserPassword	Gets or sets the user password to be used when connecting to the TargetServer.

Methods

	Name	Description
	AddAutomaticMaintenanceTask	Adds or updates an Automatic Maintenance Task on the connected machine.
	AddTask(String, Trigger, Action, String, String, TaskLogonType, String)	Creates a new task, registers the task, and returns the instance.
	AddTask(String, QuickTriggerType, String, String, String, String, TaskLogonType, String)	Creates a new task, registers the task, and returns the instance.
	BeginInit	Signals the object that initialization is starting.
	CreateFromToken	Creates a new TaskService instance from a token. Given that a TaskService instance is thread specific, this is the preferred method for multi-thread creation or asynchronous method parameters.
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject)
	Dispose	Releases all resources used by the Component. (Inherited from Component)
	Dispose(Boolean)	Releases the unmanaged resources used by the Component and optionally releases the managed resources. (Overrides ComponentDispose(Boolean))
	EndInit	Signals the object that initialization is complete.
	Equals	Determines whether the specified Object, is equal to this instance. (Overrides ObjectEquals(Object))
	Execute	Initial call for a Fluent model of creating a task.
	Finalize	Releases unmanaged resources and performs other cleanup operations before the Component is reclaimed by garbage collection. (Inherited from Component)
	FindAllTasks(PredicateTask, Boolean)	Finds all tasks matching a name or standard wildcards.
	FindAllTasks(Regex, Boolean)	Finds all tasks matching a name or standard wildcards.
	FindTask	Finds a task given a name and standard wildcards.
	GetDllResourceString	Gets a formatted string that tells the Task Scheduler to retrieve a string from a resource .dll file.
	GetEventLog	Gets the event log for this TaskService instance.
	GetFolder	Gets the path to a folder of registered tasks.
	GetHashCode	Returns a hash code for this instance. (Overrides ObjectGetHashCode)
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject)
	GetRunningTasks	Gets a collection of running tasks.
	GetService	Returns an object that represents a service provided by the Component or by its Container. (Inherited from Component)
	GetTask	Gets the task with the specified path.
	GetType	Gets the Type of the current instance. (Inherited from Object)
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject)
	NewTask	Returns an empty task definition object to be filled in with settings and properties and then registered using the RegisterTaskDefinition(String, TaskDefinition) method.
	NewTaskFromFile	Returns a TaskDefinition populated with the properties defined in an XML file.
	RunComHandlerAction	Runs an action that is defined via a COM handler. COM CLSID must be registered to an object that implements the ITaskHandler interface.
	RunComHandlerActionAsync	Runs an action that is defined via a COM handler. COM CLSID must be registered to an object that implements the ITaskHandler interface.
	SetUserSecurePassword	Sets the user password as a secure string to be used when connecting to the TargetServer.
	StartSystemTaskSchedulerManager	Starts the Task Scheduler UI for the OS hosting the assembly if the session is running in interactive mode.
	ToString	Returns a String containing the name of the Component, if any. This method should not be overridden. (Inherited from Component)
