VCCLCompilerTool.UndefineAllPreprocessorDefinitions 属性

定义

获取或设置指示是否取消定义所有之前已定义的预处理器值的值。 UndefineAllPreprocessorDefinitions 公开编译器的 /u、/u (取消定义符号) 选项的功能。

public:
 property bool UndefineAllPreprocessorDefinitions { bool get(); void set(bool value); };
public:
 property bool UndefineAllPreprocessorDefinitions { bool get(); void set(bool value); };
[System.Runtime.InteropServices.DispId(88)]
public bool UndefineAllPreprocessorDefinitions { [System.Runtime.InteropServices.DispId(88)] get; [System.Runtime.InteropServices.DispId(88)] set; }
[<System.Runtime.InteropServices.DispId(88)>]
[<get: System.Runtime.InteropServices.DispId(88)>]
[<set: System.Runtime.InteropServices.DispId(88)>]
member this.UndefineAllPreprocessorDefinitions : bool with get, set
Public Property UndefineAllPreprocessorDefinitions As Boolean

属性值

Boolean

如果取消定义所有之前定义的预处理器值,则为 true;否则为 false

下面的示例在 UndefineAllPreprocessorDefinitions 集成开发环境 (IDE) 中修改属性:

' add reference to Microsoft.VisualStudio.VCProjectEngine.  
Imports EnvDTE  
Imports Microsoft.VisualStudio.VCProjectEngine  

Public Module Module1  
    Sub Test()  
        Dim prj As VCProject  
        Dim cfgs, tools As IVCCollection  
        Dim cfg As VCConfiguration  
        Dim tool As VCCLCompilerTool  
        prj = DTE.Solution.Projects.Item(1).Object  
        cfgs = prj.Configurations  
        cfg = cfgs.Item(1)  
        tool = cfg.Tools("VCCLCompilerTool")  
        tool.UndefineAllPreprocessorDefinitions = True  
    End Sub  
End Module
