监控远程进程

我有一种停止服务的方法，但我还需要删除日志。通常这不是问题，但该过程在关闭之前可能需要一些时间。同样，虽然服务看起来已停止，但该过程确实需要额外的时间才能正确关闭。由于该进程仍在运行，我无法删除日志，因此我需要找到一种方法来监视 .exe 以了解何时可以安全地删除日志。

到目前为止，我最好的选择是 do while 循环，不幸的是，删除语句的第一次迭代抛出异常并停止程序。

do
{
// delete logs
}
while (System.Diagnostics.Process.GetProcessesByName(processName, machineName).Length > 0);

我确信有一个简单的解决方案，但我缺乏经验才是真正的问题。

I have a method that stops a service(s) but I also need to delete the logs. Usually this is not a problem but the process can take a little bit of time before closing. Again, although the service appears stopped, the process does take additional time to close properly. Since the process is still running, I cannot delete the logs so I need to find a way to monitor the .exe to know when its safe to delete the logs.

so far my best option is a do while loop, unfortunately the first iteration of the delete statement throws an exception and stops the program.

do
{
// delete logs
}
while (System.Diagnostics.Process.GetProcessesByName(processName, machineName).Length > 0);

Im sure there is a simple solution but my lack of experience is the real problem.

这可能也不是最好的答案，但您可以将循环反转为：

while (System.Diagnostics.Process.GetProcessesByName(processName, machineName).Length > 0)
{
    // delete log files.
}

我想这会在执行内容之前评估循环的条件。但根据你的说法，在进程退出之前不会执行代码。

解决这个问题的一种黑客方法是执行循环，并在满足以下条件后手动中断：

bool CloseProcessOperation = true; // Control variable incase you want to abort the loop
while (CloseProcessOperation)
{
    if (System.Diagnostics.Process.GetProcessesByName(processName, machineName).Length > 0) { break; }  
    // break if no logs exist
    // break for some other condition
    // etc

    // delete logs
}

This is probably not the best answer either, but you could invert the loop to:

while (System.Diagnostics.Process.GetProcessesByName(processName, machineName).Length > 0)
{
    // delete log files.
}

I would suppose this would evalutate the condition of the loop before executing the contents. But according to your statements, this will not execute the code until the process has exited.

A hackish way around this is to perform a loop, and break out manually once the conditions:

bool CloseProcessOperation = true; // Control variable incase you want to abort the loop
while (CloseProcessOperation)
{
    if (System.Diagnostics.Process.GetProcessesByName(processName, machineName).Length > 0) { break; }  
    // break if no logs exist
    // break for some other condition
    // etc

    // delete logs
}
