IVCCollection 類型會公開下列成員。

屬性

	名稱	描述
	Count	取得值，指出集合中物件的數目。
	VCProjectEngine	取得專案引擎的物件指標。

回頁首

方法

	名稱	描述
	GetEnumerator	傳回集合中項目的列舉程式。
	Item	選取集合中的項目。

回頁首

備註

例如， VCFilter 物件的 Files 屬性為檔案集合資料夾中。

範例

下列範例示範如何使用 EnablePREfast 和 AdditionalOptions 屬性設定 /analyze:WX- 參數。(需要兩個屬性即可)。指定 /analyze:WX- 表示程式碼分析警告不會視為錯誤，在以 /WX時。如需詳細資訊，請參閱/analyze (程式碼分析)。

如如何：編譯和執行 Automation 物件模型程式碼範例中所述，若要執行該範例，請輸入並執行範例。然後，在新的 Visual Studio執行個體，請載入 Visual C++ 專案並使用增益集管理員中啟動增益集。
