varvar 必需Required VariantVariant 由_表达式_参数引用一个表达式,指定集合的成员的位置。An expression that specifies the position of a member of the collection referred to by the expression argument.

如果是数值表达式,则 _index_参数必须为介于 0 值与该集合的 Count 属性减 1。If a numeric expression, the index argument must be a number from 0 to the value of the collection's Count property minus 1.

如果是字符串表达式,则 _index_参数必须是集合成员的名称。If a string expression, the index argument must be the name of a member of the collection.


如果为_index_参数提供的值与集合的任何现有成员都不匹配,将发生错误。If the value provided for the index argument doesn't match any existing member of the collection, an error occurs.

Item 属性是集合的默认成员,所以不需要显式指定。The Item property is the default member of a collection, so you don't have to specify it explicitly. 例如,以下两行代码是等效的。For example, the following two lines of code are equivalent.

Debug.Print Modules(0)
Debug.Print Modules.Item(0)
