字段

ValidationErrorListPropertyName

活动约束属性的名称,该属性是工作流运行验证错误的列表。The name for an activity constraint property that is a list of workflow run-time validation errors.

属性

CacheId

获取缓存的标识符,该标识符在工作流定义的作用域内是唯一的。Gets the identifier of the cache that is unique within the scope of the workflow definition.

(继承自 Activity)
CanInduceIdle

获取或设置一个值,该值指示活动是否会使工作流进入空闲状态。Gets or sets a value that indicates whether the activity can cause the workflow to become idle.

(继承自 NativeActivity)
Constraints

获取可配置的 Constraint 活动的集合,用于为 Activity 提供验证。Gets a collection of Constraint activities that can be configured to provide validation for the Activity.

(继承自 Activity)
DisplayName

获取或设置用于调试、验证、异常处理和跟踪的可选友好名称。Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking.

(继承自 Activity)
Id

获取一个标识符,该标识符在工作流定义的作用域内是唯一的。Gets an identifier that is unique in the scope of the workflow definition.

(继承自 Activity)
Implementation

活动的执行逻辑。The execution logic of the activity.

(继承自 NativeActivity)
ImplementationVersion

获取或设置活动的实现版本。Gets or sets the implementation version of the activity.

(继承自 NativeActivity)

方法

Abort(NativeActivityAbortContext)

在派生类中实现时,采取措施响应要放弃的活动。When implemented in a derived class, takes actions in response to the activity being aborted.

(继承自 NativeActivity)
AddValidationError(NativeActivityContext, ValidationError)

将验证错误添加到附加到执行上下文的运行时验证错误的列表。Adds a validation error to a list of run-time validation errors that are attached to the execution context.

CacheMetadata(ActivityMetadata)

未实现。Not implemented. 请改用 CacheMetadata(NativeActivityMetadata) 方法。Use the CacheMetadata(NativeActivityMetadata) method instead.

(继承自 NativeActivity)
CacheMetadata(NativeActivityMetadata)

创建一个 NativeActivityMetadata 对象,该对象包含工作流验证过程的运行时参数。Creates a NativeActivityMetadata object that contains runtime arguments for the workflow validation process.

Cancel(NativeActivityContext)

在派生类中实现时,运行逻辑以正常方式提前实现活动。When implemented in a derived class, runs logic to cause graceful early completion of the activity.

(继承自 NativeActivity)
Equals(Object)

确定指定对象是否等于当前对象。Determines whether the specified object is equal to the current object.

(继承自 Object)
Execute(NativeActivityContext)

调用验证活动的进程。Invokes the process that validates an activity.

GetHashCode()

作为默认哈希函数。Serves as the default hash function.

(继承自 Object)
GetType()

获取当前实例的 TypeGets the Type of the current instance.

(继承自 Object)
MemberwiseClone()

创建当前 Object 的浅表副本。Creates a shallow copy of the current Object.

(继承自 Object)
OnCreateDynamicUpdateMap(NativeActivityUpdateMapMetadata, Activity)

为动态更新创建映射时,将引发事件。Raises an event when creating a map for the dynamic update.

(继承自 NativeActivity)
OnCreateDynamicUpdateMap(UpdateMapMetadata, Activity)

为动态更新创建映射时,将引发事件。Raises an event when creating a map for the dynamic update.

(继承自 NativeActivity)
OnExecute(NativeActivityContext, Object, ValidationContext)

由派生类实现时,使用指定的本机活动和验证上下文来验证指定的对象。When implemented by a derived class, validates the specified object using the specified native activity and validation contexts.

ShouldSerializeDisplayName()

指示是否应序列化 DisplayName 属性。Indicates whether the DisplayName property should be serialized.

(继承自 Activity)
ToString()

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

(继承自 Activity)
