The ForeignKeyCollection type exposes the following members.
Properties
| Name | Description | |
|---|---|---|
.gif "Public property") |
Count | Gets the number of objects in the referenced collection. (Inherited from SmoCollectionBase.) |
|
IsSynchronized | Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (Inherited from SmoCollectionBase.) |
|
Item[Int32] | Gets a ForeignKey object in the collection by index number. |
|
Item[String] | Gets a ForeignKey object in the collection by name. |
|
Parent | Gets the Table object that is the parent of the ForeignKeyCollection object. |
|
SyncRoot | Gets an object that can be used to synchronize access to the collection. (Inherited from SmoCollectionBase.) |
