Class ListComparer<TElement>

Namespace

Microsoft.EntityFrameworkCore.ChangeTracking

Assembly

Microsoft.EntityFrameworkCore.dll

A ValueComparer<T> for lists of primitive items. The list can be typed as IEnumerable<T>, but can only be used with instances that implement IList<T>.

public sealed class ListComparer<TElement> : ValueComparer<IEnumerable<TElement>>, IEqualityComparer, IEqualityComparer<object>, IEqualityComparer<IEnumerable<TElement>>

Type Parameters

TElement

The element type.

Remarks

This comparer should be used for reference types and non-nullable value types. Use NullableValueTypeListComparer<TElement> for nullable value types.

See EF Core value comparers for more information and examples.
