TaskItems2.Item 方法 (Object)

  • 项目

返回 TaskItems 集合的一个索引成员。

命名空间：  EnvDTE80
程序集：  EnvDTE80（在 EnvDTE80.dll 中）

语法

声明
Function Item ( _
    index As Object _
) As TaskItem

TaskItem Item(
    Object index
)

TaskItem^ Item(
    [InAttribute] Object^ index
)

abstract Item : 
        index:Object -> TaskItem 

function Item(
    index : Object
) : TaskItem

参数

  • index
    类型：System.Object
    必选。要返回的项的索引。

返回值

类型：EnvDTE.TaskItem
一个 TaskItem 对象。

实现

TaskItems.Item(Object)

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。 但是对于许多对象，Index 的值还可以是等同于集合对象的字符串值。 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。

示例

此示例向任务列表中添加两个任务项，并在消息框中显示它们的某些 Item 特定属性。 有关如何作为外接程序运行此示例的更多信息，请参见如何：编译和运行自动化对象模型代码示例。
