公共方法 ComputeExpressions 基础结构。Computes the expressions of the ForLoopClass object.
公共方法 Equals （从 Object 继承。）
公共方法 Execute 基础结构。Executes the executable.
受保护方法 Finalize （从 Object 继承。）
公共方法 GetExpression 基础结构。Returns a String that contains the expression for the specified property. Null means 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 IDTSForLoop100_Execute 基础结构。Executes the executable.
公共方法 IDTSForLoop100_Validate 基础结构。Verify that the executable will successfully execute by validating all its dependencies and other items before executing it.
