正如 Joel 所建议的，正确的解决方案是在安装时在程序文件文件夹中安装快捷方式，然后将 .lnk 复制到启动文件夹。尝试创建快捷方式更加困难。
下面的代码执行以下操作：
- 它为您获取所有用户启动文件夹的路径。Environment.GetSpecialFolder 相当有限，没有对该文件夹的引用，因此您需要进行系统调用。
- 具有复制和删除快捷方式的方法。
最后，如果运行应用程序的用户是普通用户，我还想确保它在 vista 上得到妥善处理，他们将被提示输入他们的凭据。我在这里创建了一个关于这个主题的帖子，所以如果这对你很重要，请在这里查看。
如何通过提示用户输入管理员凭据在 Vista 中将文件复制为“标准用户”（即“管理选择应用程序”）？

在我编写这个解决方案时，我想到了一种更好的方法来处理这个问题，它不需要用户升级权限来禁用启动时运行。我的解决方案是在程序加载后立即检查是否存在名为 RunOnStartup 的用户范围设置。为了检测系统加载或登录时应用程序是否正在启动，我向快捷方式添加了一个参数，该快捷方式被添加到 All Users -> Startup 文件夹中，称为快捷方式。
// Quit the application if the per user setting for RunOnStartup is false.
if (args != null && args.Length > 0 && args[0].Contains("startup"))
{
if (Settings1.Default.RunOnStartup == false)
{
Application.Exit();
}
}
