如何处理并发

问题:

PacketHandler(); //包含了所有执行程序

PacketHandler 最终输出要调整的url，里面进行了N多判断，发现用2个进程测试，程序奔溃。

 

private static object asyncLock_1 = new object();

Thread thread1 = new Thread(new ThreadStart(PostTest1));
Thread thread2 = new Thread(new ThreadStart(PostTest1));
thread1.Start();
thread2.Start();
thread1.Join();
thread1.Join();

 

 1 protected void PostTest1()
 2         {
 3             lock (asyncLock4)
 4             {
 5                 //遍历用户表进行测试
 6                 DataTable dt = SqlHelper.GetDataTable(CommandType.Text, txtSql.Text, null);
 7                 if (dt != null)
 8                 {
 9                     for (int i = 0; i < dt.Rows.Count; i++)
10                     {
11                         PacketHandlert(int.Parse(txt1.Text.Trim()), int.Parse(dt.Rows[i]["Uid"].ToString()), int.Parse(dt.Rows[i]["groupId"].ToString()));
12                     }
13                 }
14             }
15         }

回答1:

处理并发无法就是锁,原子操作,单队列

回答2:

建议先注释PacketHandlert的调用，看会不会崩溃？
