C#调用cmd实现自我删除

运行完毕后删除自己：

 public class DelSelf
    {
        /// <summary>
        /// 删除自身,只删除Application对象所取得的文件
        /// </summary>
        /// <param name="args">删除延时必须大于0,也不需太长,太小可能导致删不掉!请根据计算机性能自行调整</param>
        public void Delself(params int[]args)
        {
           
           
            ProcessStartInfo psi = (args.Length<=0)?new ProcessStartInfo("cmd.exe","/C choice /C Y /N /D Y /T 3 & Del "+Application.ExecutablePath):new ProcessStartInfo("cmd.exe",string.Format("/C choice /C Y /N /D Y /T {0} & Del "+Application.ExecutablePath,args[0]))
            {
                UseShellExecute=true,
                WindowStyle=ProcessWindowStyle.Hidden,
                CreateNoWindow=true,
               
        };
            Process.Start(psi);
            Application.Exit();
        }
        /// <summary>
        /// 删除自身,删除自身所在目录下的所有文件!
        /// </summary>
        /// <param name="args">第一为时间,其他暂无他用</param>
        public void DelselfDir(params int []args)
        {

            ProcessStartInfo psi = (args.Length<=0) ?new ProcessStartInfo("cmd.exe","/C choice /C Y /N /D Y /T 3 & Del "+Application.StartupPath) : new ProcessStartInfo("cmd.exe",string.Format("/C choice /C Y /N /D Y /T {0} & Del "+Application.StartupPath,args[0]))
            {
                UseShellExecute=true,
                WindowStyle=ProcessWindowStyle.Hidden,
                CreateNoWindow=true,
            };
            Process.Start(psi);
            Application.Exit();
        }
    }
