Sequence 類別

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.

方法

  名稱 說明
公用方法 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. (繼承自 DtsContainer。)
公用方法 Dispose Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (繼承自 DtsContainer。)
公用方法 Equals Determines whether two object instances are equal. (繼承自 DtsObject。)
公用方法 Execute Runs the application, container, or package as part of a package workflow. (繼承自 DtsContainer。)
受保護的方法 Finalize (繼承自 Object。)
公用方法 GetExpression Returns a String that contains the expression for the specified property. Null means no expression is assigned.
公用方法 GetHashCode Returns the hash code for this instance. (繼承自 DtsObject。)
公用方法 GetPackagePath Returns the path of the package that the sequence container is a part of.
公用方法 GetType (繼承自 Object。)
