不管输入什么数据，点击两个按钮就直接跳出
------解决思路----------------------
为什么不单步调试看看？然后你就知道问题出在哪里了
------解决思路----------------------
跳出是什么意思？Click事件中加try catch，加断点调试，看看问题在哪
------解决思路----------------------
只能一步步调式看看
------解决思路----------------------
先F5执行以下，点击按钮看哪里报错。
定位出来错误，别人才好帮你分析。
------解决思路----------------------
有异常了呗！！F5 单步调试一下
