下面的代码是我用来 ping 8.8.8.8 的代码，但有时当我按下开始时，它只是丢包，这很重要，这很奇怪，因为我确定我没有那么多丢包，然后我暂停它并重新开始，它工作得很好，这对我来说没有意义，我很茫然。
我添加了 Thread.Sleep(); 因为我猜我启动它时程序可能没有加载，但这也很奇怪！这是一个如此小而简单的程序，它不应该有这样的问题
我还有一个问题，我应该为此设置什么超时时间，现在应用程序每秒发送一个数据包，每 900 毫秒丢弃一次，我应该把它设置为高于 900 还是会降低性能？

在此先感谢，只是让您知道我的丢包率不超过 2%，这不应该显示 40 个丢包和 0 个收到！而且它在 80% 的时间里都能正常工作！
当我暂停并再次快速启动它或第一次启动它时会再次发生这种情况。
