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.

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

Metodi
Nome | Descrizione | |
---|---|---|
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. Ereditato da DtsContainer. | |
Dispose | Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. Ereditato da DtsContainer. | |
Equals | Determines whether two object instances are equal. Ereditato da DtsObject. | |
Execute | Runs the application, container, or package as part of a package workflow. Ereditato da DtsContainer. | |
Finalize | Ereditato da 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. Ereditato da DtsObject. | |
GetPackagePath | Returns the path of the package that the sequence container is a part of. | |
GetType | Ereditato da Object. | |
LoadFromXML | This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method. Ereditato da DtsContainer. | |
MemberwiseClone | Ereditato da Object. | |
ResumeExecution | Resumes execution of the task after pausing. The task or container is resumed by the runtime engine. Ereditato da DtsContainer. | |
SaveToXML | This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method. Ereditato da DtsContainer. | |
SetExpression | Assigns the specified expression to the property. Specify nullNothingnullptrunitriferimento Null (Nothing in Visual Basic). to remove an existing expression from the property. | |
SetWrappedExecutable | Infrastruttura. Ereditato da EventsProvider. | |
SuspendExecution | Called when the executable needs to suspend. This method is called by the runtime engine. Ereditato da DtsContainer. | |
ToString | Ereditato da Object. | |
Validate | Allows the container to determine if it contains invalid settings that will prevent it from executing successfully. Ereditato da DtsContainer. |
