thread.suspend，thread.resume方法 [英] thread.suspend, thread.resume methods
本文介绍了thread.suspend，thread.resume方法的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
正在开发c＃windows appli，我有文本框，浏览按钮，上传按钮。
使用浏览按钮选择excel文件有7列，然后点击上传按钮。
每个记录发送后的线程必须暂停，直到serialport获得响应数据然后恢复该线程。然后测试响应代码（$ machine id（5个字符），响应代码（0/1/2）＃）。如果响应代码为0则只发送下一个记录。
这里是代码。

hi,
am developing c# windows appli , i have textbox,browse button, upload button.
using browse button select excel file having 7 columns,then click on upload button.
