如何调试Web表单

本文介绍了如何调试Web表单的处理方法，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 限时删除！！ hi i已经开发了一个Web应用程序，当我通过设置run as start up运行时，有一个Web表单DataTransaction.aspx 浏览器观察 localhost：3038 / DataTransaction.aspx ----->达到这个罚款。 但我想用url跟踪（通过保持断点）： localhost：3038 / DataTransaction.aspx？MID = mach1&& CNUM = c1& AMT = 1000& TOT = 01022014112233& ;
