EventSourceCreationData.CategoryResourceFile 屬性
定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
取得或設定資源檔路徑，這個資源檔包含來源的分類字串。
public:
property System::String ^ CategoryResourceFile { System::String ^ get(); void set(System::String ^ value); };public string CategoryResourceFile { get; set; }member this.CategoryResourceFile : string with get, setPublic Property CategoryResourceFile As String屬性值
分類資源檔的路徑。 預設為空字串 ("")。
範例
下列程式代碼範例會判斷名為 SampleApplicationSource 的事件來源是否已在本機計算機上註冊。 如果事件來源不存在，此範例會設定來源的訊息資源檔，並建立新的事件來源。 最後，程式代碼範例會使用 中的資源識別碼和中的DisplayNameMsgIdmessageFile資源檔案路徑，設定事件記錄檔的當地語系化顯示名稱。

備註
CategoryCount使用和 CategoryResourceFile 屬性來撰寫具有本地化類別字串的事件。 如果您撰寫事件時提供類別，事件檢視器 會顯示事件項目的類別。 事件記錄檔類別是應用程式定義的字串，可協助篩選事件，或提供有關事件的進一步資訊。 例如，您的應用程式可以針對不同的元件或不同的作業定義不同的類別。
事件類別目錄是選擇性的;如果您的應用程式未使用類別，請勿設定 CategoryCount 和 CategoryResourceFile 屬性。
如需定義事件訊息和建置事件資源檔的詳細資訊，請參閱 Platform SDK 檔中的 訊息編譯 程式一文。
