IndexedColumnCollection 类型公开以下成员。
属性
名称 | 说明 | |
---|---|---|
Count | Gets the number of objects in the referenced collection. (从 SmoCollectionBase 继承。) | |
IsSynchronized | Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (从 SmoCollectionBase 继承。) | |
Item[Int32] | Gets an IndexedColumn object in the collection by index number. | |
Item[String] | Gets an IndexedColumn object in the collection by name. | |
Parent | Gets the Server object that is the parent of the IndexedColumnCollection object. | |
SyncRoot | Gets an object that can be used to synchronize access to the collection. (从 SmoCollectionBase 继承。) |

注释
An IndexedColumnCollection object can be used to gain access to a set of indexed columns. You can use the Item property to return a specific IndexedColumn object.
