C#-Windows服务-连续Ping请求超时
一般来说，我对C#和面向对象编程是新手。我正在创建一个windows服务，每10分钟ping一个IP地址10次 如果10个请求中有7个请求超时（隔离网络漏洞），它将发送电子邮件通知系统已关闭。这部分我做对了 我面临的问题是通知系统已启动 以下是我的代码：C#-Windows服务-连续Ping请求超时,c#,service,windows-services,C#,Service,Windows Services,一般来说，我对C#和面向对象编程是新手。我正在创建一个windows服务，每10分钟ping一个IP地址10次 如果10个请求中有7个请求超时（隔离网络漏洞），它将发送电子邮件通知系统已关闭。这部分我做对了 我面临的问题是通知系统已启动 以下是我的代码： protected override void OnStart(string[] args) { eventLog.WriteEntry("Source: Service Started",Eve

上述代码在每个methodStart（）上触发系统启动电子邮件。最后是垃圾邮件。好的，阅读您的评论，我认为您需要在方法之外声明一个静态int。 例如： 如果需要执行该方法两次，则应从methodStart提取所有方法（示例名称：startUpMethod（），然后在methodStart中调用startUpMethod（））； 当您想再次调用该方法时（不管它是否在同一个方法中），可以再次调用startUpMethod（）。 这称为递归调用。 例如
你应该注意无限循环根据我的理解，你需要跟踪两次成功的执行，并在失败后发送电子邮件。我在下面的代码中添加了注释
