欄位

ValidationErrorListPropertyName

活動條件約束屬性的名稱,亦即工作流程執行階段驗證錯誤的清單。The name for an activity constraint property that is a list of workflow run-time validation errors.

屬性

CacheId

取得工作流程定義範圍內的唯一快取識別碼。Gets the identifier of the cache that is unique within the scope of the workflow definition.

(繼承來源 Activity)
CanInduceIdle

取得或設定值,這個值指出此活動是否會造成工作流程變為閒置。Gets or sets a value that indicates whether the activity can cause the workflow to become idle.

(繼承來源 NativeActivity)
Constraints

取得 Constraint 活動的集合,這些活動可以設定為提供 Activity 的驗證。Gets a collection of Constraint activities that can be configured to provide validation for the Activity.

(繼承來源 Activity)
DisplayName

取得或設定選擇性的易記名稱,這個名稱會用於偵錯、驗證、例外狀況處理及追蹤。Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking.

(繼承來源 Activity)
Id

取得工作流程定義範圍內的唯一識別碼。Gets an identifier that is unique in the scope of the workflow definition.

(繼承來源 Activity)
Implementation

活動的執行邏輯。The execution logic of the activity.

(繼承來源 NativeActivity)
ImplementationVersion

取得或設定活動的實作版本。Gets or sets the implementation version of the activity.

(繼承來源 NativeActivity)

方法

Abort(NativeActivityAbortContext)

在衍生類別中實作時,會採取動作以回應中止的活動。When implemented in a derived class, takes actions in response to the activity being aborted.

(繼承來源 NativeActivity)
AddValidationError(NativeActivityContext, ValidationError)

將驗證錯誤加入至執行內容所附加的執行階段驗證錯誤清單。Adds a validation error to a list of run-time validation errors that are attached to the execution context.

CacheMetadata(ActivityMetadata)

未實作。Not implemented. 請改用 CacheMetadata(NativeActivityMetadata) 方法。Use the CacheMetadata(NativeActivityMetadata) method instead.

(繼承來源 NativeActivity)
CacheMetadata(NativeActivityMetadata)

建立 NativeActivityMetadata 物件,這個物件包含工作流程驗證過程的執行階段引數。Creates a NativeActivityMetadata object that contains runtime arguments for the workflow validation process.

Cancel(NativeActivityContext)

在衍生類別中實作時,執行邏輯以便在非失誤性的狀況下及早完成活動。When implemented in a derived class, runs logic to cause graceful early completion of the activity.

(繼承來源 NativeActivity)
Equals(Object)

判斷指定的物件是否等於目前的物件。Determines whether the specified object is equal to the current object.

(繼承來源 Object)
Execute(NativeActivityContext)

叫用驗證活動的程序。Invokes the process that validates an activity.

GetHashCode()

做為預設雜湊函式。Serves as the default hash function.

(繼承來源 Object)
GetType()

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

(繼承來源 Object)
MemberwiseClone()

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

(繼承來源 Object)
OnCreateDynamicUpdateMap(NativeActivityUpdateMapMetadata, Activity)

建立動態更新的對應時引發事件。Raises an event when creating a map for the dynamic update.

(繼承來源 NativeActivity)
OnCreateDynamicUpdateMap(UpdateMapMetadata, Activity)

建立動態更新的對應時引發事件。Raises an event when creating a map for the dynamic update.

(繼承來源 NativeActivity)
OnExecute(NativeActivityContext, Object, ValidationContext)

在由衍生類別實作時,使用指定的原生活動和驗證內容驗證指定的物件。When implemented by a derived class, validates the specified object using the specified native activity and validation contexts.

ShouldSerializeDisplayName()

指出是否應序列化 DisplayName 屬性。Indicates whether the DisplayName property should be serialized.

(繼承來源 Activity)
ToString()

傳回包含 StringIdDisplayNameActivityReturns a String that contains the Id and DisplayName of the Activity.
