'宣告
Property EnablePREfast As Boolean

bool EnablePREfast { get; set; }

property bool EnablePREfast {
    bool get ();
    void set (bool value);
}

abstract EnablePREfast : bool with get, set

function get EnablePREfast () : boolean 
function set EnablePREfast (value : boolean)

屬性值

類型：Boolean
如果啟用機器碼則為 true (/analyze)。

備註

使用 AdditionalOptions 屬性，其他選項可以設定。

注意事項注意事項

/analyze 只能在企業 (小組開發) 版 x86 編譯器。

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。
