在使用C＃，Excel和Selenium时知道如何/何时处理内存pipe理？
我最近一直在使用C＃和Selenium来创build循环，将数据导入到网站的search参数中，这样可以将结果粘贴到Excel表格中（全部在Visual Studio中）。 我注意到，随着我越来越多的search（如n ++;），程序的速度稳步下降，甚至对于我在工作表顶部的进度条的帧速下降，这导致我相信程序的速度越来越慢。 在程序运行的每个小时后，我也一直在收集结果，似乎我的程序完成的search次数随着时间的推移而下降。
这是由于垃圾收集器没有按照我的预期工作，由于缺乏知识？ 我应该修改内存pipe理吗？ 这个循环是否足以担心内存pipe理？ 我知道垃圾收集器应该为我分配空间，我也假设它也删除不再使用的对象。 我对内存pipe理很less有任何经验，所以我只是在寻求澄清。 如果这是我应该处理的事情，是否有人能指出我正确的方向，并帮助我学习如何做？
这里是我的脚本供参考（我在Excel中通过约16,000行来完成这个特定的脚本）。
编辑：额外的问题：这是否与我正在使用像一个Try-Catch一样的内存重调用的事实？

PS：这不是一个真正的答案，但更多的评论。 希望它仍然可以帮助你
