Constructors
| RecroGridDbContext | Initializes a new instance of the RecroGridDbContext class. |
Properties
| Connection |
Returns the connection being used by this context.
(Inherited from RGDataContextBase) |
| Context |
Gets the Database context.
(Overrides RGDataContextBaseContext) |
| DataContext |
Gets the data context.
(Inherited from RGDataContextBase) |
| EntityNames |
Gets the entity names.
(Inherited from RGDataContextBase) |
| EntityTypes |
Gets the entity types.
(Inherited from RGDataContextBase) |
| NoTracking |
Gets a value indicating whether [no tracking].
(Overrides RGDataContextBaseNoTracking) |
Methods
| AddObjectTEntity |
Adds an object to the object context.
(Inherited from RGDataContextBase) |
| DeleteObjectTEntity |
Marks an object for deletion.
(Inherited from RGDataContextBase) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| ExecuteStoreCommand |
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));

| ExecuteStoreCommandAsync |
Asynchronously executes an arbitrary command directly against the data source using the existing connection.

(Inherited from RGDataContextBase) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetObjectByKeyTEntity |
Returns an object that has the specified entity key.
(Inherited from RGDataContextBase) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| OnModelCreating | It should be invoked during model creation. |
| SaveChangesAsync(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.
