我自己遇到了这个问题并且找不到解决方案，所以经过几天的研究和测试并尝试了不同的东西，我终于找到了解决这个问题的解决方案！
当您使用 Windows InstallUtil.exe 安装服务时，它会创建一个与您的服务名称相同的事件日志源并将其添加到“应用程序”事件日志中。但是，当它卸载服务时，它不会删除此源。因此，当您尝试重新安装它时，它会尝试再次添加源，但由于它已经存在，因此会出错，并且由于出现错误，它会回滚安装。
我所做的是我在我的服务中添加了用于自我安装/卸载的代码，以及一种清理它使用的事件日志的方法，以及 Windows 在第一次安装它时创建的事件日志。这种额外的方法是为我解决的问题。使用以下代码，几乎只需运行 -delevent 几次，直到它显示不存在任何内容。然后尝试再次安装，它应该可以工作。
在具有管理员权限的命令提示符中调用这些：
Service1.exe -install
Service1.exe -uninstall
Service1.exe -delevent
这是我的代码：

switch (item.ToLower())
