transactionscope mysql_TransactionScope事务操作

using (TransactionScope trans = newTransactionScope())

{try{

InsertUserBase();//它插入不成功，自己回滚

UserInfos userInfo= newUserInfos

{

UserID= “1”,

RealName= “zzl”,

};

db.UserInfos.InsertOnSubmit(userInfo);

db.SubmitChanges();

trans.Complete();

}catch(Exception)

UpdateDate=DateTime.Now,

};

db.UserBases.InsertOnSubmit(userbase);

InsertUserBase()只要出现异常，程序将自己回滚

using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required, newTransactionOptions

{

IsolationLevel=System.Transactions.IsolationLevel.ReadCommitted,

Timeout= new TimeSpan(0, 10, 0)

}, TransactionScopeAsyncFlowOption.Enabled))

one or more errors occurred(The current TransactionScope is already complete)

如果你正在使用TransactionScope和async/await在一起，你真的应该升级到4.5.1 .NET马上。

一个TransactionScope包装异步代码需要指定TransactionScopeAsyncFlowOption.Enabled在其构造。

TransactionOptions option = new TransactionOptions() { Timeout = new TimeSpan(0, 10, 0), IsolationLevel = IsolationLevel.ReadCommitted };

using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required, option, TransactionScopeAsyncFlowOption.Enabled))
