Methods
  NameDescription
Public methodStatic memberAddDbContextPoolTypeTContextService, TContextImplementation
Adds the type of the database context pool.
Public methodAddObjectTEntity
Adds an object to the object context.
(Inherited from RGDataContextBase.)
Public methodStatic memberCustomDatabaseInitialization
RGF adatbázis inicializálás után futtatható egyedi inicializálás. A visszatérési érték megjelenik a képernyőn.
Public methodDeleteObjectTEntity
Marks an object for deletion.
(Inherited from RGDataContextBase.)
Public methodDispose
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
Protected methodDispose(Boolean)
Releases unmanaged and - optionally - managed resources.
Public methodExecuteStoreCommand
Executes an arbitrary command directly against the data source using the existing connection. The command is specified using the server's native query language, such as SQL. As with any API that accepts SQL it is important to parameterize any user input to protect against a SQL injection attack. You can include parameter place holders in the SQL query string and then supply parameter values as additional arguments. Any parameter values you supply will automatically be converted to a DbParameter. context.ExecuteStoreCommand("UPDATE dbo.Posts SET Rating = 5 WHERE Author = @p0", userSuppliedAuthor); Alternatively, you can also construct a DbParameter and supply it to SqlQuery. This allows you to use named parameters in the SQL query string. context.ExecuteStoreCommand("UPDATE dbo.Posts SET Rating = 5 WHERE Author = @author", new SqlParameter("@author", userSuppliedAuthor));
(Inherited from RGDataContextBase.)
Public methodExecuteStoreCommandAsync
Asynchronously executes an arbitrary command directly against the data source using the existing connection. The command is specified using the server's native query language, such as SQL. As with any API that accepts SQL it is important to parameterize any user input to protect against a SQL injection attack. You can include parameter place holders in the SQL query string and then supply parameter values as additional arguments. Any parameter values you supply will automatically be converted to a DbParameter. context.ExecuteStoreCommandAsync("UPDATE dbo.Posts SET Rating = 5 WHERE Author = @p0", userSuppliedAuthor); Alternatively, you can also construct a DbParameter and supply it to SqlQuery. This allows you to use named parameters in the SQL query string. context.ExecuteStoreCommandAsync("UPDATE dbo.Posts SET Rating = 5 WHERE Author = @author", new SqlParameter("@author", userSuppliedAuthor));
(Inherited from RGDataContextBase.)
Protected methodFinalize
Finalizes an instance of the RGDataContext class.
(Overrides ObjectFinalize.)
Public methodGetObjectByKeyTEntity
Returns an object that has the specified entity key.
(Inherited from RGDataContextBase.)
Public methodSaveChangesAsync(CancellationToken)
Saves all changes made in this context to the database. This method will automatically call Microsoft.EntityFrameworkCore.ChangeTracking.ChangeTracker.DetectChanges to discover any changes to entity instances before saving to the underlying database. This can be disabled via Microsoft.EntityFrameworkCore.ChangeTracking.ChangeTracker.AutoDetectChangesEnabled. Multiple active operations on the same context instance are not supported. Use 'await' to ensure that any asynchronous operations have completed before calling another method on this context.
(Inherited from RGDataContextBase.)
Public methodSaveChangesAsync(Boolean, CancellationToken)
Saves all changes made in this context to the database. This method will automatically call Microsoft.EntityFrameworkCore.ChangeTracking.ChangeTracker.DetectChanges to discover any changes to entity instances before saving to the underlying database. This can be disabled via Microsoft.EntityFrameworkCore.ChangeTracking.ChangeTracker.AutoDetectChangesEnabled. Multiple active operations on the same context instance are not supported. Use 'await' to ensure that any asynchronous operations have completed before calling another method on this context.
(Inherited from RGDataContextBase.)
Public methodSelectTEntity
Projects each element of a sequence into a new form.
(Inherited from RGDataContextBase.)
Public methodStatic memberSetDefaultNamespace(Type)
Sets the default namespace and Assembly name.
Public methodStatic memberSetDefaultNamespace(String, String)
Sets the default namespace and Assembly name.
