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 a SymmetricKey object in the collection by index number. |
|
Item[ ( [ ( String] ) ] ) | Gets a SymmetricKey object in the collection by name. |
|
Parent | Gets the Database object that is the parent of the SymmetricKeyCollection object. |
|
SyncRoot | Gets an object that can be used to synchronize access to the collection. （从 SmoCollectionBase 继承。） |
