InvokeMethod 類別
定義
呼叫指定之物件或型別的公用方法。Calls a public method of a specified object or type.

範例
下列程式碼範例將示範如何建立 InvokeMethod 活動。The following code sample demonstrates creating an InvokeMethod activity. 這個範例來自于使用 InvokeMethod 活動範例。This example is from the Using the InvokeMethod Activity sample.
new InvokeMethod
{
TargetObject = new InArgument<TestClass>(ctx => testClass),
MethodName = "InstanceMethod",
Parameters =
{
new InArgument<string>("My favorite number is"),
new InArgument<int>(42),
new InArgument<string>("first item of the param array"),
new InArgument<string>("second item of the param array"),
new InArgument<string>("third item of the param array")
}
},
建構函式
| InvokeMethod() |
建立 InvokeMethod 類別的新執行個體。Creates a new instance of the InvokeMethod class. |
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) |
| 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) |
| GenericTypeArguments |
所包含方法的泛型型別引數。The generic type arguments of the contained method. |
| 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 |
在嘗試設定此屬性的值時，取得 |
| 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 AsyncCodeActivity) |
| MethodName |
活動執行時要叫用之方法的名稱。The name of the method to be invoked when the activity executes. |
| Parameters |
要叫用之方法的參數集合。The parameter collection of the method to be invoked. |
| Result |
方法作業的傳回值。The return value of the method operation. |
| RunAsynchronously |
取得或設定值，此值指出是否要以非同步方式叫用活動的方法。Gets or sets a value that indicates whether the activity's method is invoked asynchronously. |
| TargetObject |
包含要執行之方法的物件。The object that contains the method to execute. |
| TargetType |
TargetObject 的類型。The type of the TargetObject. |
方法
| BeginExecute(AsyncCodeActivityContext, AsyncCallback, Object) |
在衍生類別中實作及使用指定的執行內容、回呼方法和使用者狀態時，將非同步活動加入執行階段工作流程中的佇列。When implemented in a derived class and using the specified execution context, callback method, and user state, enqueues an asynchronous activity in a run-time workflow. (繼承來源 AsyncCodeActivity) |
| CacheMetadata(ActivityMetadata) |
未實作。Not implemented. 請改用 CacheMetadata(CodeActivityMetadata)。Use CacheMetadata(CodeActivityMetadata) instead. (繼承來源 AsyncCodeActivity) |
| CacheMetadata(CodeActivityMetadata) |
做為虛擬方法，並轉換由非同步活動引數中快取反映取得的資料。Serves as a virtual method and converts information obtained by cache reflection into arguments for an asynchronous activity. (繼承來源 AsyncCodeActivity) |
| Cancel(AsyncCodeActivityContext) |
在衍生類別中實作及使用指定的執行環境資訊時，會通知工作流程執行階段非同步活動作業已提早完成。When implemented in a derived class and using the specified execution environment information, notifies the workflow runtime that the asynchronous activity operation has reached an early completion. 做為虛擬方法。Serves as a virtual method. (繼承來源 AsyncCodeActivity) |
| EndExecute(AsyncCodeActivityContext, IAsyncResult) |
在衍生類別中實作及使用指定的執行環境資訊時，會通知工作流程執行階段相關聯的非同步活動作業已完成。When implemented in a derived class and using the specified execution environment information, notifies the workflow runtime that the associated asynchronous activity operation has completed. (繼承來源 AsyncCodeActivity) |
| 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) |
| GetHashCode() |
作為預設雜湊函數。Serves as the default hash function. (繼承來源 Object) |
| GetType() |
取得目前執行個體的 Type。Gets 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(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 AsyncCodeActivity) |
| 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 String 的 Id 和 DisplayName 的 Activity。Returns a String that contains the Id and DisplayName of the Activity. (繼承來源 Activity) |
