Table<TEntity>.DeleteOnSubmit Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Puts an entity from this table into a pending delete state.

Namespace: System.Data.Linq
Assembly: System.Data.Linq (in System.Data.Linq.dll)

Syntax

'Declaration
Public Sub DeleteOnSubmit ( _
    entity As TEntity _
)

public void DeleteOnSubmit(
    TEntity entity
)

Parameters

entity
Type: TEntity
The entity to be deleted.

Implements

ITable<TEntity>.DeleteOnSubmit(TEntity)

Remarks

The removed entity does not disappear from the query results until after SubmitChanges is called. Disconnected entities must first be attached before they can be deleted.

Note:
LINQ to SQL does not support or recognize cascade-delete operations. If you want to delete a row in a table that has constraints against it, you must either set the ON DELETE CASCADE rule in the foreign-key constraint in the database, or use your own code to first delete the child objects that prevent the parent object from being deleted. Otherwise, an exception is thrown.
