oralce 事务处理，调用这个方法，程序就死了。急。。
public void RunOracleTransaction(string myConnString)
{
OracleConnection myConnection = new OracleConnection(myConnString);
myConnection.Open();

OracleCommand myCommand = myConnection.CreateCommand();
OracleTransaction myTrans;

// Start a local transaction
myTrans = myConnection.BeginTransaction(IsolationLevel.ReadCommitted);
// Assign transaction object for a pending local transaction
myCommand.Transaction = myTrans;

// try
//{
myCommand.CommandText = "INSERT INTO Dept (DeptNo, Dname, Loc) values (50, 'TECHNOLOGY', 'DENVER')";
myCommand.ExecuteNonQuery();
myCommand.CommandText = "INSERT INTO Dept (DeptNo, Dname, Loc) values (60, 'ENGINEERING', 'KANSAS CITY')";
myCommand.ExecuteNonQuery();
myTrans.Commit();
Console.WriteLine("Both records are written to database.");
// }
// catch (Exception e)
//{
myTrans.Rollback();
/// throw e;
//Console.WriteLine(e.ToString());
Console.WriteLine("Neither record was written to database.");
// }
//finally
//{
myConnection.Close();
//}
}

[解决办法]
using(TransactionScope scope = new TransactionScope()) {
//方法1 //方法2: scope.Complete(); }
