010002C#编程小技巧

1 获取系统进程

命名空间：

using System.Diagnostics;

关键代码：

Process[] processes = Process.GetProcesses();
System.Console.WriteLine("进程ID 进程名字 优先级 启动时间");
foreach (Process p in processes)
{
    Console.WriteLine(String.Format("{0} {1} {2} {3}", p.Id, p.ProcessName, p.BasePriority, p.StartTime));
}

 2 快捷键

        private void TXTXML_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Modifiers == Keys.Control && e.KeyCode == Keys.A)
            {
                ((TextBox)sender).SelectAll();
            }
        }

 3 十进制转换为十六进制

        /// <summary>
        /// 将十进制数据转换为十六进制数
        /// </summary>
        /// <param name="ten">十进制数</param>
        /// <returns>十六进制数</returns>
        public static string Ten2Sixten(int ten)
        {
            string six = Convert.ToString(ten, 16);
            if (!string.IsNullOrEmpty(six))
            {
                six = six.ToUpper();
            }

            return six;
        }

        /// <summary>
        /// 将十六进制数转换为十进制数
        /// </summary>
        /// <param name="sixten">十六进制数</param>
        /// <returns>十进制数</returns>
        public static int Sixten2Ten(string sixten)
        {
            return Convert.ToInt32(sixten, 16);
        }

        /// <summary>
        /// 将十进制数转换为二进制数
        /// </summary>
        /// <param name="ten">十进制</param>
        /// <returns>二进制</returns>
        public static string Ten2Two(int ten)
        {
            return Convert.ToString(ten, 2);
        }

        /// <summary>
        /// 将二进制说转换为十进制数
        /// </summary>
        /// <param name="two">二进制数</param>
        /// <returns>十进制数</returns>
        public static int Two2Ten(string two)
        {
            return Convert.ToInt32(two, 2);
        }
