public EventsDataSet ReadEventsList()

傳回值

類型：WebSvcEvents.EventsDataSet
EventsDataSet包含事件識別碼、事件名稱和事件的來源。

備註

事件來源是 Project Server 的實體，例如專案、行事曆、自訂欄位、 LookupTable，依此類推。事件名稱包含前置事件與後的事件。例如，撥打電話時 PSI 發佈專案和專案發佈前，都會觸發此專案發佈前事件。發佈資料庫中儲存專案之後，就會觸發專案發佈後置事件。

Project Server 權限

權限	描述
ManageServerEvents	可讓使用者管理的伺服器端事件的事件處理常式。通用權限。

範例

下列範例會示範ReadEventsList方法。建立和修改事件處理常式及兩個不同的 XML 檔案中寫入未修改的資料集和已修改的資料集後, 之應用程式使用ReadEventsList擷取所有 Project Server 事件的清單，然後將其寫入第三個 XML 檔案。

範例 ProjectServerServices.dll proxy 組件中使用SvcEvent命名空間。

注意事項
在某些情況下，則可能需要只要事件處理常式關聯程序，才可完成的 60 秒。必須設定睡眠時間間隔，使時間足以完成此程序。否則，錯誤編製索引的資料集可能會終止應用程式。如果應用程式不會執行未完成上述步驟，將無法可靠的結果。在這個範例中，建立事件處理常式所允許的時間為 45 秒，並允許存取的事件處理常式的時間為 5 秒數。在特定環境中，實驗會需要以決定需要，才可完成這些作業的時間量。 The ConfigClientEndpoints method uses an app.config file for setting the WCF binding, behavior, and endpoint. For information about creating a PSI proxy assembly and an app.config file, see Prerequisites for WCF-Based Code Samples.
