Examples

Using Collections

Remarks

A ColumnCollection object can be used to gain access to a set of columns. You can use the Item[String] property to return a specific Column object.

Thread Safety

Any public static (Shared in Microsoft Visual Basic) members of this type are safe for multithreaded operations. Any instance members are not guaranteed to be thread safe.

Properties

Count Count Count

Gets the number of objects in the referenced collection.

(Inherited from SmoCollectionBase)
IsSynchronized IsSynchronized IsSynchronized

Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe.

(Inherited from SmoCollectionBase)
Item[Int32] Item[Int32] Item[Int32]

Gets a Column object in the collection by index number.

Item[String] Item[String] Item[String]

Gets a Column object in the collection by name.

Parent Parent Parent

Gets the SqlSmoObject object that is the parent of the ColumnCollection object.

SyncRoot SyncRoot SyncRoot

Gets an object that can be used to synchronize access to the collection.
