Name | Beschreibung | |
---|---|---|
Count | Gets the number of objects in the referenced collection. (Geerbt von SmoCollectionBase.) | |
IsSynchronized | Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (Geerbt von SmoCollectionBase.) | |
Item[Int32] | Gets a Check object in the collection by index number. | |
Item[String] | Gets a Check object in the collection by name. | |
Parent | Gets the SqlSmoObject object that is the parent of the CheckCollection object. | |
SyncRoot | Gets an object that can be used to synchronize access to the collection. (Geerbt von SmoCollectionBase.) |
