通过

VCCLCompilerTool.EnablePREfast 属性

  • 项目

获取或设置是否启用本机代码分析。

命名空间：  Microsoft.VisualStudio.VCProjectEngine
程序集：  Microsoft.VisualStudio.VCProjectEngine（在 Microsoft.VisualStudio.VCProjectEngine.dll 中）

语法

声明
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)

属性值

类型：System.Boolean
true 表示启用代码分析 (/analyze)。

备注

使用 AdditionalOptions 属性，附加选项进行设置。

说明说明

/analyze 只有企业 (团队开发人员) 版本针对 x86 编译器。

示例

下面的示例演示如何使用 EnablePREfast 和 AdditionalOptions 属性设置 /analyze:WX- 开关。(需要两个属性。) 指定 /analyze:WX- 意味着代码分析警告不被视为错误，则编译 /WX时。有关更多信息，请参见 /analyze（代码分析）。

如 如何：编译和运行自动化对象模型代码示例所述，若要运行此示例中，输入并运行此示例。然后，在 Visual Studio新实例，加载一个 Visual C++ 项目并使用外接程序管理器激活外接程序。
