[於黾]

那这个Screenshotslist到底是哪里来的,你代码里根本没有啊,我ctrl+F搜索根本找不到

[於黾]

你那个Info根本是个字符串 不加锁顶多是字符串拼接了一半的时候另一个线程就给取出来了,造成数据不完整 跟卡死不卡死没关系 问题是你现在代码不全,连定义都找不到,更不知道其他关键地方你是否省略了什么不得了的代码

[於黾]

反而是一些无关紧要的代码放的太多,导致关键代码都找不到到底在哪里

[张三疯1]

我把完整贴出来东西太多。

[於黾]

如果你连代码里哪些是跟线程相关的内容,哪些是无关的内容都搞不清楚,就只能自己慢慢排查了

[於黾]

你开另一个线程去获取信息,这个信息最终保存到哪里去了? 写入文件了,记录到数据库了,还是显示在界面上了? base.sendCtlChar("ENTER");//发送指令表示兑奖成功 这是啥? 所以我一开始就让你写伪代码,而不是让你放出全部的代码 如果你放出了全部代码,但是都没有详细的注释,那跟没放一样

[张三疯1]

我贴完整代码吧！

上面上截屏线程类

[luhr]

阻塞在这里了吧 var length = socket.EndReceive(ar); 看下非阻塞啊 看下System.Threading.ManualResetEvent，线程等待WaitOne()和set() 应该是等待socket接收完你才能取值吧socket编程，来人看下我说的对不对

[张三疯1]

socket 这种方式接收值 会不会有问题。

[张三疯1]

有没有大牛出来指点一下。这个问题卡啦我好久啦！！！

[张三疯1]

一直找不到问题出在什么地方。

[於黾]

代码太多,注释太少 建议把跟通信无关的,只不过是判断需要显示什么字符串的东西都拿掉 然后挑重点,写个伪代码,把关键的会产生阻塞的代码写清楚就好了

Z65443344 麻烦帮忙看看，谢谢！！

[於黾]

public bool prizeTicketData(Ticket ticket) 这个方法是在哪里调用的,怎么看也不是以线程方式启动的

[张三疯1]

总的问题就是。一个截屏线程在不断的获取信息类。别一个多线程。要不继获取值截屏线程内的信息进行下一个操作！

[张三疯1]

结贴。问题已解决！！！
