vs2019调试时，取消线程abort终止导致异常中断方法

线程调用abort()会触发ThreadAbortException异常，调试时不想触发该异常的解决方式。

1、初始化线程

 1         /// <summary>
 2         /// 初始化
 3         /// </summary>
 4         public void InitTask()
 5         {
 6             //构建线程，启动
 7             _Thread = new Thread(new ThreadStart(() =>
 8             {
 9                 try
10                 {
11                     //开始循环
12                     while (_isTaskStart)
13                     {
14                             Thread.Sleep(100);  //do something
15                     }
16                 }
17                 catch (Exception ex)
18                 {
19                     //TODO:记录日志
20                 }
21                 _drawThread = null;
22             }));
23             _drawThread.IsBackground = true;
24             _drawThread.Start();
25         }

2、终止线程

 1          /// <summary>
 2         /// 释放资源
 3         /// </summary>
 4         protected void DisposeThread()
 5         {
 6               // 释放。
 7               if (_drawThread != null)
 8               {
 9                   _drawThread.Abort();
10                   while (_drawThread != null && _drawThread.IsAlive)
11                   {
12                        Thread.Sleep(10);
13                    }
14                         _drawThread = null;
15                 }
16           }
