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 Type。Gets 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 String 的 Id 和 DisplayName 的 Activity。Returns a String that contains the Id and DisplayName of the Activity. (继承自 Activity) |
| UpdateInstance(NativeActivityUpdateContext) |
更新 NativeActivity 的该实例。Updates the instance of NativeActivity. (继承自 NativeActivity) |
