c#方法一：
TransactionOptions transactionOption = new TransactionOptions();
//设置事务隔离级别
transactionOption.IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted;
// 设置事务超时时间为60秒
transactionOption.Timeout = new TimeSpan(0, 0, 60);
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required, transactionOption))
{
int id = 0;
try
{
//do something
scope.Complete();
}
catch (Exception ex)
{
throw ex;
}
finally
{
scope.Dispose();
}
}
ｃ＃方法二： SqlTransaction sqlTransaction = sqlConnection.BeginTransaction();
SqlCommand sqlCommand = new SqlCommand();
sqlCommand.Transaction = sqlTransaction;
sqlTransaction.Commit();
try
{
// 利用sqlcommand进行数据操作
...
// 成功提交
sqlTransaction.Commit();
}
catch(Exception ex)
{
// 出错回滚
sqlTransaction.Rollback();
}
finally
{
cnn.Close();
trans.Dispose();
cnn.Dispose();
}
