DbConnection.BeginDbTransactionAsync(IsolationLevel, CancellationToken) Method

Definition

Asynchronously starts a database transaction.

protected:
 virtual System::Threading::Tasks::ValueTask<System::Data::Common::DbTransaction ^> BeginDbTransactionAsync(System::Data::IsolationLevel isolationLevel, System::Threading::CancellationToken cancellationToken);
protected virtual System.Threading.Tasks.ValueTask<System.Data.Common.DbTransaction>? BeginDbTransactionAsync (System.Data.IsolationLevel isolationLevel, System.Threading.CancellationToken cancellationToken);
protected virtual System.Threading.Tasks.ValueTask<System.Data.Common.DbTransaction> BeginDbTransactionAsync (System.Data.IsolationLevel isolationLevel, System.Threading.CancellationToken cancellationToken);
abstract member BeginDbTransactionAsync : System.Data.IsolationLevel * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<System.Data.Common.DbTransaction>
override this.BeginDbTransactionAsync : System.Data.IsolationLevel * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<System.Data.Common.DbTransaction>
Protected Overridable Function BeginDbTransactionAsync (isolationLevel As IsolationLevel, cancellationToken As CancellationToken) As ValueTask(Of DbTransaction)

Parameters

isolationLevel
IsolationLevel

One of the enumeration values that specifies the isolation level for the transaction to use.

cancellationToken
CancellationToken

A token to cancel the asynchronous operation.

Returns

ValueTask<DbTransaction>

A task whose Result property is an object representing the new transaction.

Remarks

The default implementation of this asynchronous method delegates to its synchronous counterpart and returns a completed Task, potentially blocking the calling thread.

Data providers that support asynchronous programming should override the default inmplementation using asynchronous I/O operations.
