基于C#生成随机数示例

using System;namespace DotNet.Utilities{  /// BaseRandom /// 产生随机数 /// 随机数管理，最大值、最小值可以自己进行设定。 public class BaseRandom { public static int Minimum = 100000;    public static int Maximal = 999999;    public static int RandomLength = 6;    private static string RandomString = "0123456789ABCDEFGHIJKMLNOPQRSTUVWXYZ";    private static Random Random = new Random(DateTime.Now.Second);    #region public static string GetRandomString() 产生随机字符    /// 产生随机字符    /// <returns>字符串</returns>    public static string GetRandomString()    {      string returnValue = string.Empty;      for (int i = 0; i < RandomLength; i++)      {        int r = Random.Next(0, RandomString.Length - 1);        returnValue += RandomString[r];      }      return returnValue;    }    #endregion    #region public static int GetRandom()    /// <summary>    /// 产生随机数    /// </summary>    /// <returns>随机数</returns>    public static int GetRandom() {  return Random.Next(Minimum, Maximal); } #endregion    #region public static int GetRandom(int minimum, int maximal)    /// <summary> /// 产生随机数 /// </summary> /// <param name="minimum">最小值</param> /// <param name="maximal">最大值</param> /// <returns>随机数</returns>    public static int GetRandom(int minimum, int maximal) {      return Random.Next(minimum, maximal); } #endregion }}
