WindowClosedEventArgs.GetRuntimeId 方法

定義

擷取與此事件相關聯的消費者介面自動化執行時間識別碼 (識別碼) 。

public:
 cli::array <int> ^ GetRuntimeId();
public int[] GetRuntimeId ();
member this.GetRuntimeId : unit -> int[]
Public Function GetRuntimeId () As Integer()

傳回

Int32[]

引發事件之視窗的消費者介面自動化執行時間識別碼。

範例

在下列範例中,視窗關閉事件的處理常式會確定關閉視窗的執行時間識別碼是否位於開啟視窗的識別碼清單中。 如果執行時間識別碼存在,則會從清單中移除。

備註

當應用程式收到視窗關閉事件時, sender 事件處理常式的 參數無法用來取得已關閉之視窗的相關資訊,因為對應的Microsoft 消費者介面自動化專案已不再有效。 使用 GetRuntimeId 來比對視窗與已知的識別碼。
