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);
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>

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

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.
