JScript 支持使用索引属性，但不支持声明新索引属性。

参数

注释

If the call to the Contains method returns true, you can access the specified element in the collection by using the syntax ForEachVariableMappings[index]. However, if the Contains method returns false, this property throws an exception. In C#, this property is the indexer for the ForEachVariableMappings class.
