MemberEntry Class

Definition

Provides access to change tracking information and operations for a given property or navigation property.

Scalar properties use the derived class PropertyEntry, reference navigation properties use the derived class ReferenceEntry, and collection navigation properties use the derived class CollectionEntry.

Instances of this class are returned from methods when using the ChangeTracker API and it is not designed to be directly constructed in your application code.

Constructors

MemberEntry(InternalEntityEntry, IPropertyBase)

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

Properties

CurrentValue

Gets or sets the value currently assigned to this property. If the current value is set using this property, the change tracker is aware of the change and DetectChanges() is not required for the context to detect the change.

EntityEntry

The EntityEntry to which this member belongs.

InternalEntry

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

IsModified

For non-navigation properties, gets or sets a value indicating whether the value of this property has been modified and should be updated in the database when SaveChanges() is called.

For navigation properties, gets or sets a value indicating whether any of foreign key property values associated with this navigation property have been modified and should be updated in the database when SaveChanges() is called.

Metadata

Gets the metadata that describes the facets of this property and how it maps to the database.

Explicit Interface Implementations

IInfrastructure<InternalEntityEntry>.Instance

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

Extension Methods

GetInfrastructure<T>(IInfrastructure<T>)

Gets the value from a property that is being hidden using IInfrastructure<T>.

This method is typically used by database providers (and other extensions). It is generally not used in application code.

IInfrastructure<T> is used to hide properties that are not intended to be used in application code but can be used in extension methods written by database providers etc.
