如何实现上位机程序开机自动启动呢？

实现很简单，通过C#操作注册表来实现。

代码已经写好，直接复制过去，在主程序里调用一下即可。

        /// <summary>          /// 修改程序在注册表中的键值          /// </summary>          /// <param name="isAuto">true:开机启动,false:不开机自启</param>         private void AutoStart(bool isAuto = true)        {            if (isAuto == true)            {                RegistryKey R_local = Registry.CurrentUser;                RegistryKey R_run = R_local.CreateSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run");                 R_run.SetValue("ProjectName", System.Windows.Forms.Application.ExecutablePath);                R_run.Close();                R_local.Close();            }            else             {                RegistryKey R_local = Registry.CurrentUser;                RegistryKey R_run = R_local.CreateSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run");                R_run.DeleteValue("ProjectName", false);                R_run.Close();                R_local.Close();            }        }
