本文实例所述为C#生成随机数的类文件,按要求产生一些随机数,最大值、最小值可以自己进行设定。代码简单,可放在你的公共库内供调用使用。
类文件具体代码如下:
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 } }
