PreviousTrackingServiceAttribute 類別

定義

警告:已過時

The System.Workflow.* types are deprecated. Instead, please use the new types from System.Activities.*

指出前一版使用 TrackingService 的型別。Indicates the type of the TrackingService that was used prior to the current version.

public ref class PreviousTrackingServiceAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Class, AllowMultiple=true)]
public sealed class PreviousTrackingServiceAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Class, AllowMultiple=true)]
[System.Obsolete("The System.Workflow.* types are deprecated.  Instead, please use the new types from System.Activities.*")]
public sealed class PreviousTrackingServiceAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Class, AllowMultiple=true)>]
type PreviousTrackingServiceAttribute = class
    inherit Attribute
[<System.AttributeUsage(System.AttributeTargets.Class, AllowMultiple=true)>]

部署包含新版本 TrackingService 實作的組件時,此屬性會套用至追蹤類別的新版本,以識別前一版的組件。When an assembly containing a new version of a TrackingService implementation is deployed, this attribute is applied to the new version of the tracking service class to identify the assembly of the previous version. 這可以讓執行階段運用較新的追蹤服務來處理在使用前一版追蹤服務時已保存,但在實作新版本之後繼續執行的工作流程。This allows the runtime to utilize the newer tracking service for workflows that were using persisted while using the previous version of the tracking service, but resumed after the new version was implemented.

建構函式

PreviousTrackingServiceAttribute(String)

(繼承來源 Attribute)
GetType()

取得目前執行個體的 TypeGets the Type of the current instance.

(繼承來源 Object)
IsDefaultAttribute()

在衍生類別中覆寫時,表示這個執行個體的值是衍生類別的預設值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(繼承來源 Attribute)
Match(Object)

在衍生類別中覆寫時,會傳回值,表示這個執行個體是否等於指定物件。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(繼承來源 Attribute)
MemberwiseClone()

建立目前 Object 的淺層複製。Creates a shallow copy of the current Object.

(繼承來源 Object)
ToString()

傳回代表目前物件的字串。Returns a string that represents the current object.

(繼承來源 Object)

明確介面實作

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

將一組名稱對應至一組對應的分派識別項 (Dispatch Identifier)。Maps a set of names to a corresponding set of dispatch identifiers.

(繼承來源 Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

擷取物件的類型資訊,可以用來取得介面的類型資訊。Retrieves the type information for an object, which can be used to get the type information for an interface.

(繼承來源 Attribute)
_Attribute.GetTypeInfoCount(UInt32)

擷取物件提供的類型資訊介面數目 (0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(繼承來源 Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)
