Classe Sequence

Defines a control flow that is a subset of the package control flow. Use Sequence containers to group the package into multiple separate control flows that each contain one or more tasks and containers that run within the overall package control flow. This class cannot be inherited.

Propriedade pública FailPackageOnFailure 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. (Herdado de DtsContainer.)
Propriedade pública FailParentOnFailure Gets or sets a Boolean that defines whether the parent container fails when a child container fails. (Herdado de DtsContainer.)
Propriedade pública ForcedExecutionValue If the ForceExecutionValue property is set to true, gets or sets a value that specifies the optional execution value that the package returns. (Herdado de DtsContainer.)
Propriedade pública ForceExecutionResult Gets or sets a DTSForcedExecResult enumeration value that specifies the forced execution result of the container. (Herdado de DtsContainer.)
Propriedade pública ForceExecutionValue Gets or sets a Boolean that indicates whether the execution value of the container should be forced to contain a particular value. (Herdado de DtsContainer.)
Propriedade pública ID Returns the ID, which is a GUID, of the DtsContainer. The value is read-only. (Herdado de DtsContainer.)
Propriedade pública IsDefaultLocaleID A Boolean that indicates whether the container uses the default locale. This property is read-only. (Herdado de DtsContainer.)
Propriedade pública IsolationLevel Gets or sets the isolation level of the transaction in the DtsContainer object. (Herdado de DtsContainer.)

Propriedade pública MaximumErrorCount Gets or sets an Integer value that indicates the maximum number of errors that can occur before the DtsContainer object stops running. (Herdado de DtsContainer.)
Propriedade pública Name Gets or sets the name of the DtsContainer. (Herdado de DtsContainer.)
Propriedade pública Parent Returns the parent container. The value is read-only. (Herdado de DtsContainer.)
Propriedade pública PrecedenceConstraints Returns a collection of PrecedenceConstraint objects that describe the precedence constraints that link container-level containers and tasks into an ordered control flow
Propriedade pública Properties Returns a collection of DtsProperty objects that contain properties relating to the sequence container.

Métodos

  Nome Descrição
Método público AcceptBreakpointManager This method is called by the run-time engine when a task or container is created, and passes it a BreakpointManager manager to allow the task to create, remove, and check the status of breakpoints. This method is called by the runtime and is not used in code. (Herdado de DtsContainer.)
Método público Dispose Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (Herdado de DtsContainer.)
Método público Equals Determines whether two object instances are equal. (Herdado de DtsObject.)
Método público Execute Runs the application, container, or package as part of a package workflow. (Herdado de DtsContainer.)
Método protegido Finalize (Herdado de Object.)
Método público GetExpression Returns a String that contains the expression for the specified property. Null means no expression is assigned.
Método público GetHashCode Returns the hash code for this instance. (Herdado de DtsObject.)
Método público GetPackagePath Returns the path of the package that the sequence container is a part of.
Método público GetType (Herdado de Object.)
Método público LoadFromXML This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method. (Herdado de DtsContainer.)
Método protegido MemberwiseClone (Herdado de Object.)
Método público ResumeExecution Resumes execution of the task after pausing. The task or container is resumed by the runtime engine. (Herdado de DtsContainer.)
Método público SaveToXML This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method. (Herdado de DtsContainer.)
Método público SetExpression Assigns the specified expression to the property. Specify nullNothingnullptrunituma referência nula (Nothing no Visual Basic) to remove an existing expression from the property.
Método protegido SetWrappedExecutable Infraestrutura. (Herdado de EventsProvider.)
Método público SuspendExecution Called when the executable needs to suspend. This method is called by the runtime engine. (Herdado de DtsContainer.)
Método público ToString (Herdado de Object.)
Método público Validate Allows the container to determine if it contains invalid settings that will prevent it from executing successfully. (Herdado de DtsContainer.)
