示例1: CommittableTransaction

//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)
{
    Console.Write("Commit or Rollback? [C|R] ");
    ConsoleKeyInfo c = Console.ReadKey();
    Console.WriteLine();

    if ((c.KeyChar == 'C') || (c.KeyChar == 'c'))
    {
        tx.Commit();
        break;
    }
    else if ((c.KeyChar == 'R') || (c.KeyChar == 'r'))
    {
        tx.Rollback();
        break;
