Table<'TEntity>.DeleteOnSubmit Method ('TEntity)
.NET Framework (current version)
Puts an entity from this table into a pending delete state.
Assembly: System.Data.Linq (in System.Data.Linq.dll)
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. For more information, see Data Retrieval and CUD Operations in N-Tier Applications (LINQ to SQL).
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. |
