Syntax

'Declaration
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

Parameters

  • index
    Type: Object

    Required. The index of the item to return.

Return Value

Type: EnvDTE.TaskItem
A TaskItem object.

Remarks

The value passed to Index is an integer that is an index to an object in its collection. For many objects, though, the value of Index can also be a string value that equates to an object in the collection. The exact value that is accepted by Item, though, depends upon the collection and its implementation.

The Item method throws a ArgumentException exception if the collection cannot find the object that corresponds to the index value.

Examples

This example adds two task items to the task list and displays some of their Item specific properties in message boxes. For more information about how to run this example as an add-in, see How to: Compile and Run the Automation Object Model Code Examples.
