JScript 支持使用索引属性，但不支持声明新索引属性。
参数
- index
类型：System.Object
The name, ID, description, or index of the item to locate in the collection.
属性值
类型：Microsoft.SqlServer.Dts.Runtime.PipelineComponentInfo
A PipelineComponentInfo object.
注释
If the call to the Contains method returns true, you can access the specified element in the collection by using the syntax PipelineComponentInfos[index]. However, if the Contains method returns false, this property throws an exception. In C#, this property is the indexer for the PipelineComponentInfos class
示例
The following code example retrieves an item from the collection using two methods. The first method uses the pInfos[…] syntax to retrieve the entire object located in the first position of the collection and place it in the pInfo object. You can now retrieve all properties from the pInfo object as usual. The second method demonstrates how to retrieve a specific property, the description, from the "merge" object in the collection using the name as the indexer.
