FileSystemTask 类型公开以下成员。

构造函数

	名称	说明
	FileSystemTask	Initializes a new instance of the FileSystemTask class.

属性

	名称	说明
	Attributes	Gets or sets the attributes to apply to the file or directory.
	DebugMode	A Boolean indicating if a task should check if breakpoints are enabled.
	Destination	Gets or sets the destination folder or file.
	ExecutionValue	Returns the number of successful operations performed by the task. This field is read-only. （覆盖 Task.ExecutionValue。）
	IsDestinationPathVariable	Gets or sets a Boolean that indicates whether Destination information is located in a package variable.
	IsSourcePathVariable	Gets or sets a Boolean that indicates whether Source information is located in a package variable.
	Operation	Gets or sets a value from the DTSFileSystemOperation enumeration that determines the type of operation to perform.
	OperationName	Gets or sets the name of the task.
	OverwriteDestinationFile	Gets or sets a Boolean that indicates whether the task will overwrite destination files.
	PreservedAttributes	Gets or sets the Data Transformation Services preserved attributes.
	Source	Gets or sets the source file or directory. If IsSourcePathVariable is set to true, gets or sets the package variable name representing the source file or directory.
	SuspendRequired	Gets or sets a Boolean that indicates if tasks should suspend when they encounter a breakpoint. This value is set by the runtime engine for tasks and containers when a breakpoint is encountered.
	Version	*** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only. （从 Task 继承。）

方法

	名称	说明
	AcceptBreakpointManager	Passes a BreakpointManager to the task. This method is called by the runtime and is not used in code.
	CanUpdate	*** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. （从 Task 继承。）
	Equals	Determines whether two object instances are equal. （从 DtsObject 继承。）
	Execute	Runs the task. （覆盖 Task.Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object)。）
	GetConnectionID	Gets a String containing the ID of the connection. （从 Task 继承。）
	GetConnectionName	Gets a String containing the name of the connection. （从 Task 继承。）
	GetHashCode	Returns the hash code for this instance. （从 DtsObject 继承。）
	GetType	（从 Object 继承。）
	InitializeTask	Initializes the properties associated with the task. This method is called by the runtime and is not used in code. （覆盖 Task.InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker)。）
	LoadFromXML	This method is not callable by your application code. To load a package that is saved as .xml to the hard drive, use the Application.LoadPackage method.
	ResumeExecution	Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
	SaveToXML	This method is not callable by your application code. To save a package as .xml, use the Application.SaveToXml method.
	SuspendExecution	Indicates that the executable needs to suspend. This method is called by the runtime engine.
	ToString	（从 Object 继承。）
	Update	*** Member deprecated; see Remarks. ***    This method updates the old package XML with the new package XML if CanUpdate is set to true. （从 Task 继承。）
	Validate	Verifies that the task is properly configured. （覆盖 Task.Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging)。）
