C#线程

Question

我创建了多个线程怎么能让它一个一个执行完成一个再执行下一个

Answer 1

是这样的
for (i = 0; i < 8; i++)
{
 Thread tThread = new Thread(new ThreadStart(RunsOnWorkerThread));
 tThread.Start();
}
怎么能让它RunsOnWorkerThread执行完在执行下一个循环

Answer 2

那开线程做啥？直接执行好了for (i = 0; i < 8; i++)
{
 RunsOnWorkerThread();
 tThread.Start();
}

Answer 3

for (i = 0; i < 8; i++)
{
 RunsOnWorkerThread();
}

Answer 4

大家看看这个这就是我要做的当上传多个文件时它只传两个就重复第二个其它的不传了.如果不用线程的话界面就死一做的那些上已经上传字节数也不显示string[] path;
