Solution3.Item 方法
返回 Projects 集合的一个索引成员。
命名空间： EnvDTE90
程序集： EnvDTE90（在 EnvDTE90.dll 中）
语法
声明
Function Item ( _
index As Object _
) As Project
Project Item(
Object index
)
Project^ Item(
[InAttribute] Object^ index
)
abstract Item :
index:Object -> Project
function Item(
index : Object
) : Project
参数
- index
类型：Object
返回值
类型：Project
一个 Project 对象。
备注
传递给 Index 的值是一个整数，该整数是某对象在其集合中的索引。 Index 的值还可以是等同于集合中某个对象的字符串值。 但是，Item 接受的精确值取决于集合及其实现。
如果集合找不到对应于索引值的对象，则 Item 方法引发 ArgumentException 异常。
