我是C＃和面向对象编程的新手。我正在创建一个Windows服务，它会每10分钟ping一次IP地址10次。
如果10个请求中有7个请求超时（隔离网络闪烁），它将发送一封电子邮件通知系统已关闭。我有这个部分。
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",EventLogEntryType.SuccessAudit);
timer.Enabled = true;
timer.Interval = (10 * 60 * 1000);
timer.Elapsed += new System.Timers.ElapsedEventHandler(methodStart);
}
public void methodStart(object sender, ElapsedEventArgs e)
{
Ping p = new Ping();
PingReply r;
string s = "SYSTEM-IP-ADDRESS";
int upCounter=0;
int downCounter = 0;
bool sysDown = false;
try
{
for (int i = 0; i < 10; i++)
{
r = p.Send(s);
if (r.Status == IPStatus.Success)
{
eventLog.WriteEntry("Ping to " + s.ToString() + "[" + r.Address.ToString() + "]" + " Successful"
+ " Response delay = " + r.RoundtripTime.ToString() + " ms" + "\n", EventLogEntryType.SuccessAudit);
upCounter++;
}
else
{
downCounter++;
}
}
if(downCounter>=7)
{
//LOG ENTRY
eventLog.WriteEntry("Unable to reach the system after 7 Timeouts! Email notification Sent.", EventLogEntryType.FailureAudit);
// EMAIL NOTIFICATION
downCounter = 0;
}
else
{
sysDown = false;
}
}
catch (Exception ex)
{
//EXCEPTION HANDLING
}
loopCounter++;
if(sysDown==false && loopCounter>2)
{
eventLog.WriteEntry("The Tool Is Up Email Notification Sent", EventLogEntryType.SuccessAudit);
// EMAIL NOTIFICATION
loopCounter = 0;
}
}
我想要实现的是，ping超时7 =＆gt;时间并发送一封电子邮件，说明它已关闭。如果系统在接下来的2次执行期间启动，请发送一封电子邮件，说明系统已启动（我的代码每2次执行一次电子邮件，说明系统已启动）。
如何实现这一目标？
更新1 ：我有电子邮件逻辑。
更新2 ：Vibhav Ramcharan的解决方案会在每次执行 startMethod（）时触发系统通知。
System Down通知的阈值为70％，即一次执行期间连续7次ping失败。
假设系统出现故障。触发电子邮件将通知系统故障。
系统启动时，执行成功两次。发送电子邮件通知系统已启动。
以上代码会在每个 methodStart（）上触发系统电子邮件。最终，垃圾邮件。

好的，阅读你的评论我认为你需要在方法之外声明的静态int。 例如：
class Program{
private static int loopCounter = 0;
static void Main(string[] args)
{
// code
}
public void methodStart(object sender, ElapsedEventArgs e){
// code
}
}
如果需要执行两次方法，则应该从methodStart中提取所有方法（示例名称：startUpMethod（），然后在methodStart中调用startUpMethod（））; 当你想再次调用该方法时（如果它在同一方法内部无关紧要），你再次调用startUpMethod（）。 这称为递归调用。 实施例。
public void public void methodStart(object sender, ElapsedEventArgs e){
startUpMethod();
}
public void startUpMethod()
{
//do something
if(repeat)
startUpMethod()
}
你应该照顾无限循环

根据我的理解，您需要跟踪两次成功执行并在失败后发送电子邮件。我在下面的代码中添加了评论。
protected override void OnStart(string[] args){
var timer = new Timer
{
Enabled = true,
Interval = (10 * 60 * 1000)
};
timer.Elapsed += new System.Timers.ElapsedEventHandler(methodStart);
}
private int loopCounter = 0;
bool sysDown = false;
// Used to count the number of successful executions after a failure.
int systemUpAfterFailureCount = 0;
public void methodStart(object sender, ElapsedEventArgs e)
{
Ping p = new Ping();
PingReply r;
string s = "SYSTEM-IP-ADDRESS";
int upCounter = 0;
int downCounter = 0;
try
{
for (int i = 0; i < 10; i++)
{
r = p.Send(s);
if (r.Status == IPStatus.Success)
upCounter++;
else
downCounter++;
}
if (downCounter >= 7)
{
// LOG ENTRY
// EMAIL NOTIFICATION
downCounter = 0;
// The system has failed
sysDown = true;
}
else
{
// Before changing the sysDown flag, check if the system was previously down
// This is the first successful execution after the failure
if (sysDown)
systemUpAfterFailureCount++;
// This will allow systemUpAfterFailureCount to increase if it is Ex: 1 and sysDown = false (Your success execution limit is 2, which we control at the IF block below)
if (systemUpAfterFailureCount > 1)
systemUpAfterFailureCount++;
sysDown = false;
}
}
catch (Exception ex)
{
//EXCEPTION HANDLING
}
loopCounter++;
// Check if the system is down, if it is up execute the following code for a maximum of 2 executions.
if (sysDown==false && systemUpAfterFailureCount <= 2)
{
// LOG ENTRY
loopCounter = 0;
// Send email for successful executions after a failure, limited to 2.
if (systemUpAfterFailureCount <= 2)
{
// EMAIL NOTIFICATION
}
// After two successful executions have occured, reset the counter
if (systemUpAfterFailureCount == 2)
{
systemUpAfterFailureCount = 0;
}
}
}

以下代码有效且需要。
public void methodStart(object sender, ElapsedEventArgs e)
{
Ping p = new Ping();
PingReply r;
string s = "SYSTEM-IP-ADDRESS";
try
{
for (int i = 0; i < 10; i++)
{
r = p.Send(s);
if (r.Status == IPStatus.Success)
{
SuccessNoti();
}
else
{
UnsuccessfulNoti();
}
}
}
catch (Exception ex)
{
UnsuccessfulNoti();
}
}
}
public void SuccessNoti()
{
if ((string.Compare(status, "Down", false) == 0) && Successcount >= 7)
{
using (MailMessage mail = new MailMessage())
{
using (SmtpClient SmtpServer = new SmtpClient(smtp))
{
// EMAIL NOTIFICATION
Successcount = 0;
status = null;
}
}
}
else
{
if (string.Compare(status, "Down", false) == 0)
{
Successcount = Successcount + 1;
}
}
}
public void sendfailureNotofication()
{
if (failureCount >= 7 && !(string.Compare(status, "Down", false) == 0))
{
status = "Down";
using (MailMessage mail = new MailMessage())
{
using (SmtpClient SmtpServer = new SmtpClient(smtp))
{
// EMAIL NOTIFICATION
failureCount = 0;
status = "Down";
}
}
}
else
{
if (!(string.Compare(status, "Down", false) == 0))
{
failureCount = failureCount + 1;
}
}
}
