在我的案例中，它在关闭服务后起了作用。检查服务。如果是，请关闭，并在任务管理器中查看是否有服务进程。

在我的情况下，我执行taskkill /f /im dongleserver.exe， 其中dongleserver.exe是我程序的exe文件。

然后我就可以重新安装我的程序了。

可能有几种原因导致服务卡在“标记为删除”中。

SysInternals' Process Explorer is opened. Closing it should lead to automatic removal of the service. Task Manager is opened. Microsoft Management Console (MMC) is opened. To ensure all instances are closed, run taskkill /F /IM mmc.exe. Services console is opened. This is the same as the previous point, since Services console is hosted by MMC. Event Viewer is opened. Again, this is the same as the third point. The key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\{service name} exists. Someone else is logged into the server and has one of the previously mentioned applications opened. An instance of Visual Studio used to debug the service is open.

这意味着服务在services.msc中仍然被列为禁用。 只要关闭服务。MSC并以管理员身份重新打开… 该服务将不会被列出。现在，使用命令安装服务，

安装“服务路径”

打开Services控制台也可能导致这种情况。直到关闭该服务，Windows才会删除该服务。

最有可能的是，删除服务失败是因为

protected override void OnStop()

停止服务时抛出错误。将内容包装在try catch中可以防止标记删除错误

protected override void OnStop()
{
            try
            {
                //things to do
            }
            catch (Exception)
            {
            }

}
