DbSet<TEntity>.AddRangeAsync Method

Definition

Namespace:

Microsoft.EntityFrameworkCore

Assembly:

Microsoft.EntityFrameworkCore.dll

Package:

Microsoft.EntityFrameworkCore v8.0.0

Overloads

AddRangeAsync(TEntity[])	Begins tracking the given entities, and any other reachable entities that are not already being tracked, in the Added state such that they will be inserted into the database when SaveChanges() is called.
AddRangeAsync(IEnumerable<TEntity>, CancellationToken)	Begins tracking the given entities, and any other reachable entities that are not already being tracked, in the Added state such that they will be inserted into the database when SaveChanges() is called.

AddRangeAsync(TEntity[])

Begins tracking the given entities, and any other reachable entities that are not already being tracked, in the Added state such that they will be inserted into the database when SaveChanges() is called.

public virtual System.Threading.Tasks.Task AddRangeAsync (params TEntity[] entities);

abstract member AddRangeAsync : 'Entity[] -> System.Threading.Tasks.Task
override this.AddRangeAsync : 'Entity[] -> System.Threading.Tasks.Task

Public Overridable Function AddRangeAsync (ParamArray entities As TEntity()) As Task

Parameters

entities

TEntity[]

The entities to add.

Returns

Task

A task that represents the asynchronous operation.

Remarks

This method is async only to allow special value generators, such as the one used by 'Microsoft.EntityFrameworkCore.Metadata.SqlServerValueGenerationStrategy.SequenceHiLo', to access the database asynchronously. For all other cases the non async method should be used.

See EF Core change tracking and Using AddRange, UpdateRange, AttachRange, and RemoveRange for more information and examples.

AddRangeAsync(IEnumerable<TEntity>, CancellationToken)

Begins tracking the given entities, and any other reachable entities that are not already being tracked, in the Added state such that they will be inserted into the database when SaveChanges() is called.

public virtual System.Threading.Tasks.Task AddRangeAsync (System.Collections.Generic.IEnumerable<TEntity> entities, System.Threading.CancellationToken cancellationToken = default);

abstract member AddRangeAsync : seq<'Entity (requires 'Entity : null)> * System.Threading.CancellationToken -> System.Threading.Tasks.Task
override this.AddRangeAsync : seq<'Entity (requires 'Entity : null)> * System.Threading.CancellationToken -> System.Threading.Tasks.Task

Public Overridable Function AddRangeAsync (entities As IEnumerable(Of TEntity), Optional cancellationToken As CancellationToken = Nothing) As Task

Parameters

entities

IEnumerable<TEntity>

The entities to add.

cancellationToken

CancellationToken

A CancellationToken to observe while waiting for the task to complete.

Returns
