Answer 1

FbTransactionOptions를 사용할 수 있습니다.

FbTransaction transaction = Connection.BeginTransaction(
    FbTransactionOptions.ReadCommitted  |
    FbTransactionOptions.Write|
    FbTransactionOptions.RecVersion|
    FbTransactionOptions.NoWait |
    );

.

IsolationLevel에서도보십시오 :

• IsolationLevel.ReadUncommitted
• IsolationLevel.ReadCommitted
• IsolationLevel.RepeatableRead
• IsolationLevel.Serializable

할 수 있습니다 :

FbTransaction transaction = Connection.BeginTransaction( IsolationLevel.Serializable );
