ISaveChangesInterceptor Interface

Definition

Namespace:

Microsoft.EntityFrameworkCore.Diagnostics

Assembly:

Microsoft.EntityFrameworkCore.dll

Package:

Microsoft.EntityFrameworkCore v9.0.0

Source:

ISaveChangesInterceptor.cs

Allows interception of the DbContext.SaveChanges and DbContext.SaveChangesAync methods.

public interface ISaveChangesInterceptor : Microsoft.EntityFrameworkCore.Diagnostics.IInterceptor

type ISaveChangesInterceptor = interface
    interface IInterceptor

Public Interface ISaveChangesInterceptor
Implements IInterceptor

Derived

Microsoft.EntityFrameworkCore.Diagnostics.SaveChangesInterceptor

Implements

IInterceptor

Remarks

SaveChanges interceptors can be used to view, change, or suppress execution of the SaveChanges call and modify the result before it is returned to EF.

Consider inheriting from SaveChangesInterceptor if not implementing all methods.

Use AddInterceptors(IInterceptor[]) to register application interceptors.

Extensions can also register interceptors in the internal service provider. If both injected and application interceptors are found, then the injected interceptors are run in the order that they are resolved from the service provider, and then the application interceptors are run last.

See EF Core interceptors for more information and examples.
