DataContext.SubmitChanges Method

Definition

Namespace:

System.Data.Linq

Assembly:

System.Data.Linq.dll

Computes the set of modified objects to be inserted, updated, or deleted, and executes the appropriate commands to implement the changes to the database.

Overloads

SubmitChanges()	Computes the set of modified objects to be inserted, updated, or deleted, and executes the appropriate commands to implement the changes to the database.
SubmitChanges(ConflictMode)	Sends changes that were made to retrieved objects to the underlying database, and specifies the action to be taken if the submission fails.

Remarks

If override methods are present for insert, update, or delete, SubmitChanges executes these methods instead of the default LINQ to SQL commands.

SubmitChanges starts a transaction and will roll back if an exception occurs while SubmitChanges is executing. However, this does not roll back the changes in memory or tracked by the DataContext; those changes will need to be rolled back manually. You can start with a new instance of the DataContext if the changes in memory are to be discarded.
