Methods

AddObjectTEntity Adds an object to the object context.
DeleteObjectTEntity Marks an object for deletion.
EqualsDetermines 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. 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));
FinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object)
GetHashCodeServes as the default hash function.
(Inherited from Object)
GetObjectByKeyTEntity Returns an object that has the specified entity key.
GetTypeGets the Type of the current instance.
(Inherited from Object)
MemberwiseCloneCreates a shallow copy of the current Object.
(Inherited from Object)
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.
SaveChangesAsync(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.
SelectTEntity Projects each element of a sequence into a new form.
ToStringReturns a string that represents the current object.
