EventHandlerClass 类型公开以下成员。

构造函数

  名称 说明
公共方法 EventHandlerClass 基础结构。Initializes a new instance of the EventHandlerClass class.

页首

属性

  名称 说明
公共属性 CreationName 基础结构。Gets the name that is used by the runtime engine to create an instance of the EventHandlerClass. This property is read-only.
公共属性 DebugMode 基础结构。Gets or sets a Boolean that indicates whether a task should check if breakpoints are enabled.
公共属性 DelayValidation 基础结构。Gets or sets a Boolean that indicates whether validation of the task is delayed until run time. The default value is false.
公共属性 Description 基础结构。Gets or sets the description of the EventHandlerClass object.
公共属性 Disable 基础结构。Gets a Boolean that indicates whether the EventHandlerClass object is disabled.
公共属性 Executables 基础结构。Gets a collection of executable objects in this container which run when the event occurs. This property is read-only.
公共属性 ExecutionDuration 基础结构。Gets a value that indicates the amount of time that the container spent in execution, in milliseconds. This property is read-only.
公共属性 ExecutionResult 基础结构。Gets a value that indicates the success or failure of the execution of the EventHandlerClass object.
公共属性 ExecutionStatus 基础结构。Gets a value that indicates the current status of the execution of the EventHandlerClass object at the time of the call.
公共属性 FailPackageOnFailure 基础结构。Gets or sets a Boolean that indicates whether the package fails when a child container fails. This property is used on containers, not the package itself.
公共属性 FailParentOnFailure 基础结构。Gets or sets a Boolean that indicates whether the parent container fails when a child container fails.
公共属性 ForcedExecutionValue 基础结构。If the ForceExecutionValue property is set to true, gets or sets a value that specifies the optional execution value the package returns.
公共属性 ForceExecutionResult 基础结构。Gets or sets a DTSForcedExecResult enumeration value that specifies the forced execution result of the container.
公共属性 ForceExecutionValue 基础结构。Gets or sets a Boolean that indicates whether the execution value of the container should be forced to contain a particular value.
公共属性 ID 基础结构。Gets the ID, which is a GUID, of the EventHandlerClass. The value is read-only.
公共属性 IDTSSuspend100_SuspendRequired 基础结构。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.
公共属性 IsDefaultLocaleID 基础结构。Gets a Boolean that indicates whether the container uses the default locale. This property is read-only.
公共属性 IsolationLevel 基础结构。Gets or sets the isolation level of the transaction in the EventHandlerClass object.
公共属性 LocaleID 基础结构。Gets or sets an Integer that indicates the Microsoft Win32® localeID to use when the EventHandlerClass object is executed.
公共属性 LogEntryInfos 基础结构。Gets a collection of log entry definitions. This property is read-only.
公共属性 LoggingMode 基础结构。Gets or sets a value from the DTSLoggingMode enumeration that indicates the logging mode of the container.
公共属性 LoggingOptions 基础结构。Gets an object that contains properties that indicates the filtering and logging resource for containers. This property is read-only.
公共属性 MaximumErrorCount 基础结构。Gets or sets an Integer value that specifies the maximum number of errors that can occur before the EventHandlerClass object stops running.
公共属性 Name 基础结构。Gets or sets the name of the EventHandlerClass.
公共属性 Parent 基础结构。Gets the parent container. The value is read-only.
公共属性 PrecedenceConstraints 基础结构。Gets a collection of precedence constraints, if any, found on the executable objects in this container. This property is read-only.
公共属性 Properties 基础结构。Gets a collection of IDTSProperty100 objects. This property is read-only.
公共属性 StartTime 基础结构。Gets the time when the container starts execution. This property is read-only.
公共属性 StopTime 基础结构。Gets the time when the container stops execution. This property is read-only.
公共属性 SuspendRequired 基础结构。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.
公共属性 TransactionOption 基础结构。Gets or sets a value that indicates whether the container participates in transactions.
公共属性 VariableDispenser 基础结构。Gets a variable dispenser object so that variables associated with the container can be locked for reading or writing.
公共属性 Variables 基础结构。Gets a collection object that contains the variables associated with this container. This property is read-only.

方法

  名称 说明
公共方法 AcceptBreakpointManager 基础结构。Passes a IDTSBreakpointManager100 to a task. The task will use the breakpoint manager to create, remove, and check the status of breakpoints. This method is called by the runtime and is not used in code.
公共方法 ComputeExpressions 基础结构。Computes the expressions of this EventHandlerClass object.
公共方法 Equals （从 Object 继承。）
公共方法 Execute 基础结构。Runs the application, container, or package as part of a package workflow.
受保护方法 Finalize （从 Object 继承。）
公共方法 GetExpression 基础结构。Returns the expression for the specified property or nullnull 引用（在 Visual Basic 中为 Nothing） if no expression is assigned.
公共方法 GetHashCode （从 Object 继承。）
公共方法 GetParentID 基础结构。Gets the parent identifier of this container.
公共方法 GetType （从 Object 继承。）
公共方法 IDTSSuspend100_ResumeExecution 基础结构。Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
公共方法 IDTSSuspend100_SuspendExecution 基础结构。Notifies that the executable needs to suspend. This method is called by the runtime engine.
公共方法 LoadFromXML 基础结构。Loads an EventHandlerClass from the specified XML document.
受保护方法 MemberwiseClone （从 Object 继承。）
公共方法 RegenerateID 基础结构。Creates a new GUID for the container and updates the container ID property.
公共方法 ResumeExecution 基础结构。Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
公共方法 SaveToXML 基础结构。Saves an EventHandlerClass to the specified XML document.
公共方法 SetExpression 基础结构。Assigns the specified expression to the property. Specify nullnull 引用（在 Visual Basic 中为 Nothing） to remove an existing expression from the property.
公共方法 SuspendExecution 基础结构。Notifies that the executable needs to suspend. This method is called by the runtime engine.
公共方法 ToString （从 Object 继承。）
公共方法 Validate 基础结构。Allows the container to determine if it contains invalid settings that will prevent it from executing successfully.
