Defines an abstract class that provides the methods that all objects that are run by the run-time engine are required to inherit and implement.

    Inherits DtsObject
用法
Dim instance As Executable

public abstract class Executable : DtsObject

public ref class Executable abstract : public DtsObject

[<AbstractClassAttribute>]
type Executable =  
    class
        inherit DtsObject

Executable 类型公开以下成员。

方法

	名称	说明
	Equals	Determines whether two object instances are equal. （从 DtsObject 继承。）
	Execute	Executes the executable.
	Finalize	（从 Object 继承。）
	GetHashCode	Returns the hash code for this instance. （从 DtsObject 继承。）
	GetType	（从 Object 继承。）
	MemberwiseClone	（从 Object 继承。）
	ToString	（从 Object 继承。）
	Validate	Verify that the executable will successfully execute by validating all its dependencies and other items before executing it. The component that implements this method is the component that is being validated.

注释

The Executable abstract base class is inherited by the abstract base class DtsContainer, which is then inherited by the abstract base class EventsProvider. The EventsProvider class is subsequently inherited by the following containers that are used often in code.

• ForEachLoop Class

• ForLoop Class

• Package Class

• Sequence Class

• TaskHost Class

此类型的任何公共 static（在 Visual Basic 中为 Shared） 成员都是线程安全的。不保证所有实例成员都是线程安全的。
