![]() ![]() | ChangeConflicts | Returns a collection of objects that caused concurrency conflicts when SubmitChanges was called. |
![]() ![]() | DeferredLoadingEnabled | Specifies whether to delay-load one-to-many or one-to-one relationships. |
![]() ![]() | LoadOptions | Gets or sets the DataLoadOptions associated with this DataContext. |
![]() ![]() | Log | Specifies the destination to write the SQL query or command. |
![]() ![]() | Mapping | Returns the MetaModel on which the mapping is based. |
![]() ![]() | ObjectTrackingEnabled | Instructs the framework to track the original value and object identity for this DataContext. |

![]() ![]() | DeleteDatabase | Deletes the associated database. |
![]() ![]() | Dispose() | Releases all resources used by the DataContext. |
![]() ![]() | Dispose(Boolean) | Releases resources used by the DataContext. |
![]() ![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() | ExecuteDynamicDelete | Called inside delete override methods to redelegate to LINQ to SQL the task of generating and executing dynamic SQL for delete operations. |
![]() ![]() | ExecuteDynamicInsert | Called inside insert override methods to redelegate to LINQ to SQL the task of generating and executing dynamic SQL for insert operations. |
![]() ![]() | ExecuteDynamicUpdate | Called inside update override methods to redelegate to LINQ to SQL the task of generating and executing dynamic SQL for update operations. |
![]() ![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetChangeSet | Provides access to the modified objects tracked by DataContext. |
![]() ![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() | GetTable(Type) | Returns a collection of objects of a particular type, where the type is defined by the type parameter. |
![]() ![]() | GetTable<TEntity>() | Returns a collection of objects of a particular type, where the type is defined by the TEntity parameter. |
![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | Refresh(RefreshMode, IEnumerable) | Refreshes a collection of entity objects according to the specified mode. |
![]() ![]() | Refresh(RefreshMode, Object) | Refreshes an entity object according to the specified mode. |
![]() ![]() | Refresh(RefreshMode, array<Object>) | Refreshes an array of entity objects according to the specified mode. |
![]() ![]() | 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. |
![]() ![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
