Public Sub New ()

예제

다음 샘플에서는 의 CommittableTransaction 새 인스턴스를 만들고 커밋합니다.

//Create a committable transaction
tx = new CommittableTransaction();

SqlConnection myConnection = new SqlConnection("server=(local)\\SQLExpress;Integrated Security=SSPI;database=northwind");
SqlCommand myCommand = new SqlCommand();

//Open the SQL connection
myConnection.Open();

//Give the transaction to SQL to enlist with
myConnection.EnlistTransaction(tx);

myCommand.Connection = myConnection;

// Restore database to near it's original condition so sample will work correctly.
myCommand.CommandText = "DELETE FROM Region WHERE (RegionID = 100) OR (RegionID = 101)";
myCommand.ExecuteNonQuery();

// Insert the first record.
myCommand.CommandText = "Insert into Region (RegionID, RegionDescription) VALUES (100, 'MidWestern')";
myCommand.ExecuteNonQuery();

// Insert the second record.
myCommand.CommandText = "Insert into Region (RegionID, RegionDescription) VALUES (101, 'MidEastern')";
myCommand.ExecuteNonQuery();

// Commit or rollback the transaction
while (true)

CommittableTransaction(TimeSpan)

Source:

CommittableTransaction.cs

지정된 CommittableTransaction 값을 사용하여 timeout 클래스의 새 인스턴스를 초기화합니다.

public:
 CommittableTransaction(TimeSpan timeout);

public CommittableTransaction (TimeSpan timeout);

new System.Transactions.CommittableTransaction : TimeSpan -> System.Transactions.CommittableTransaction

Public Sub New (timeout As TimeSpan)

매개 변수

timeout

TimeSpan

트랜잭션이 중단되기 전에 존재할 수 있는 최대 시간입니다.

CommittableTransaction(TransactionOptions)

Source:

CommittableTransaction.cs

지정된 트랜잭션 옵션을 사용하여 CommittableTransaction 클래스의 새 인스턴스를 초기화합니다.

public:
 CommittableTransaction(System::Transactions::TransactionOptions options);

public CommittableTransaction (System.Transactions.TransactionOptions options);

new System.Transactions.CommittableTransaction : System.Transactions.TransactionOptions -> System.Transactions.CommittableTransaction

Public Sub New (options As TransactionOptions)

매개 변수

options

TransactionOptions

새 트랜잭션에 사용할 트랜잭션 옵션을 설명하는 TransactionOptions 구조체입니다.

예외

ArgumentException

options이 잘못되었습니다.

예제

다음 샘플에서는 옵션을 사용하여 의 CommittableTransaction 새 인스턴스를 만들고 중단합니다.
