CodeDelegate2.ProjectItem 属性

定义

获取与 CodeDelegate2 对象关联的 ProjectItem 对象。

public:
 property EnvDTE::ProjectItem ^ ProjectItem { EnvDTE::ProjectItem ^ get(); };
public:
 property EnvDTE::ProjectItem ^ ProjectItem { EnvDTE::ProjectItem ^ get(); };
[System.Runtime.InteropServices.DispId(4)]
public EnvDTE.ProjectItem ProjectItem { [System.Runtime.InteropServices.DispId(4)] [System.Runtime.InteropServices.TypeLibFunc(1024)] get; }
[<System.Runtime.InteropServices.DispId(4)>]
[<get: System.Runtime.InteropServices.DispId(4)>]
[<get: System.Runtime.InteropServices.TypeLibFunc(1024)>]
member this.ProjectItem : EnvDTE.ProjectItem
Public ReadOnly Property ProjectItem As ProjectItem

属性值

ProjectItem

一个 ProjectItem 对象,表示包含该委托的项目。


在进行了某些类型的编辑之后,代码模型元素(例如类、结构、函数、特性、委托等)的值可能变为非确定性的,这意味着不能确定它们的值始终保持不变。 有关详细信息,请参阅 "代码模型元素值在 使用代码模型查找代码时 可能发生变化" (Visual Basic) "。
