10/25/2012

返回一个字符串，它包含此对象的存根 (stub) 定义。

命名空间： EnvDTE
程序集： EnvDTE（在 EnvDTE.dll 中）

语法

声明
ReadOnly Property Prototype ( _
    Flags As Integer _
) As String

string this[
    int Flags
] { get; }

property String^ Prototype[[InAttribute] int Flags] {
    String^ get ([InAttribute] int Flags);
}

abstract Prototype : string

JScript 不支持索引属性。

参数

Flags
类型：System.Int32
可选。一个 vsCMPrototype 值，该值指示字符串的内容，例如仅参数名、参数类型和完整的唯一签名等。默认情况下，所有标志都设置为 Off。

属性值

类型：System.String
一个字符串，表示此 CodeFunction 的存根定义。

备注

说明
在进行某些类型的编辑之后，代码模型元素（如类、结构、函数、特性、委托等）的值可能是非确定性的，这意味着不能指望它们的值总是保持不变。有关更多信息，请参见使用代码模型查找代码 (Visual Basic) 中的“代码模型元素的值可能会更改”一节。
