【问题标题】:Get the transaction id when the transaction is committed事务提交时获取事务id
【发布时间】:2018-01-15 13:03:03
【问题描述】:
我正在使用事务范围的 IEnlistmentNotification 接口,我想在范围完成后访问 commit 方法中的当前事务 id,如下所示:
public void Commit(Enlistment enlistment)
{
string transactionId = Transaction.Current.TransactionInformation.LocalIdentifier;
enlistment.Done();
}
但我收到一个错误,因为现在 transaction.current 为空。
根据我的检查,登记实例具有 transactionId 的私有成员,但我无法访问它以获得他的保护级别。
有没有其他方法可以在作用域完成时获取事务id?

【解决方案1】:
using (TransactionScope scope = new TransactionScope())
{
using (YourContext context = new YourContext())
{
//DB operations
context.SaveChanges();
}
Transaction.Current.TransactionCompleted += Current_TransactionCompleted;
TransactionInformation info = Transaction.Current.TransactionInformation;
string transactionId = Guid.Empty.Equals(info.DistributedIdentifier) ? info.LocalIdentifier : info.DistributedIdentifier.ToString();
scope.Complete();
}
//For the transaction completed event:
private void Current_TransactionCompleted(object sender, TransactionEventArgs e)
{
//e.Transaction.TransactionInformation contains the Id
}
