1、usingSystem;usingSystem.Threading;//银行帐户类classAccount{intbalcince;//余额Randomr二newRandoni();publicAccount(intinitidl){baltinee二initial;}//取钱intWithdraw(intamount){if(baldnee<0){thrownewException(zz余额为负!")；}lock(this){if(balance>=amount){Console.WriteLine(z，原有余额:"+btilanc

2、e);Console.WriteLineCz支取金额:-"+amount);balanee=balance一amount;Console.WriteLine(/z现有余额:"+balance);returnamount;}else{return0;//拒绝交易}}}//测试交易publicvoidDoTrcinsactions(){//支取随机的金额100次for(inti=0;i<100;i++){Withdraw(r.Next(1,100));}}}classTestApp{publicstaticvoidMain()//建立10

3、个线程同时进行交易Threadthreads=newThread[10];Accountacc=newAccount(1000):for(inti=0;i<1();i++){Thi'eadt二newThread(newThreadStart(acc・DoTrdnsactions));threads[i]=t;}for(inti=0;i<10;i卄){threads[i].Start();}}}
