Error message

重启服务 {serv_name} 时失败。未找到该服务！

What it means

Thrown by RestartSelf() when the app's own Windows service (named "LKYOfficeToolsService", derived from AppAttribute.ServiceName) cannot be located. The check uses Com_ServiceOS.Query.IsCreated, which returns false both when the service is genuinely not installed and when ServiceController.GetServices() throws due to insufficient privileges — the exception is swallowed and mapped to false. So this error conflates "service missing" with "not running elevated".

Solutions

1. Relaunch the application as Administrator — IsCreated returns false when it cannot enumerate services due to missing privileges.
2. Verify the service exists from an elevated shell: `sc query LKYOfficeToolsService`. If absent, run the app's service-creation step first.
3. Confirm the service name matches AppAttribute.ServiceName ("LKYOfficeToolsService"); a manual rename or DisplayName mismatch causes the lookup to miss.
4. If developing, add a privilege pre-check before IsCreated so the error message distinguishes "not installed" from "not elevated".

Example fix

// before
if (!Query.IsCreated(serv_name))
{
    throw new Exception($"重启服务 {serv_name} 时失败。未找到该服务！");
}

// after — separate privilege failure from genuine absence
var principal = new WindowsPrincipal(WindowsIdentity.GetCurrent());
if (!principal.IsInRole(WindowsBuiltInRole.Administrator))
{
    throw new Exception($"重启服务 {serv_name} 需要管理员权限。");
}
if (!Query.IsCreated(serv_name))
{
    throw new Exception($"服务 {serv_name} 未安装，请先执行服务创建步骤。");
}

// Run before RestartSelf: confirm elevation, then service presence.
var principal = new WindowsPrincipal(WindowsIdentity.GetCurrent());
if (!principal.IsInRole(WindowsBuiltInRole.Administrator))
{
    new Log("RestartSelf 需要 Administrator 权限，否则无法枚举服务。");
    return;
}
if (!Com_ServiceOS.Query.IsCreated(AppAttribute.ServiceName))
{
    new Log($"服务 {AppAttribute.ServiceName} 未安装，请先执行服务创建步骤。");
    return;
}

When it happens

Trigger: Calling RestartSelf() when (a) the service was never created by the app's service-installation step, (b) the service was manually uninstalled or renamed, or (c) the process runs without Administrator rights so GetServices() throws Win32Exception, which IsCreated catches and returns false.

Common situations: Running the tool interactively without elevation; executing RestartSelf before the service-creation flow completed; a prior uninstall removed the service; antivirus or another tool interfering with service enumeration; service registered under a different name than the computed "LKYOfficeToolsService".
