C#經常使用自界說函數小結。本站提示廣大學習愛好者:(C#經常使用自界說函數小結)文章只能為提供參考,不一定能成為您想要的結果。以下是C#經常使用自界說函數小結正文
本文實例總結了幾個C#經常使用的自界說函數,異常適用。分享給年夜家供年夜家參考。詳細以下:
1.將數組轉成字符串
/// <summary> /// 將數組轉成字符串 /// </summary> /// <param name="glue">分隔符</param> /// <param name="pieces">要字符串數組</param> private string Implode(char glue,string[] pieces) { string result = string.Empty; int count = pieces.Length; for (int i = 0; i < count;i++ ) { if(i==0){ result = pieces[i]; }else{ result = result + glue.ToString() + pieces[i]; } } return result; }
2.DateTime時光格局轉換為Unix時光戳格局
/// <summary> /// DateTime時光格局轉換為Unix時光戳格局 /// </summary> /// <param name=”time”></param> /// <returns></returns> private int ConvertDateTimeInt(System.DateTime time) { System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1)); return (int)(time - startTime).TotalSeconds; }
3.生成某個規模內的隨機數
/// <summary> /// 取得某個規模內的隨機數 /// </summary> /// <param name="start">隨機數的下界</param> /// <param name="end">隨機數的上界</param> /// <returns>[minValue, maxValue)規模內的隨機整數</returns> private int GetRandomInt(int minValue, int maxValue) { Random r = new Random(Chaos_GetRandomSeed()); return r.Next(minValue, maxValue); } /// <summary> /// 加密隨機數生成器,生成隨機種子 /// </summary> /// <returns></returns> private static int Chaos_GetRandomSeed() { byte[] bytes = new byte[4]; System.Security.Cryptography.RNGCryptoServiceProvider rng = new System.Security.Cryptography.RNGCryptoServiceProvider(); rng.GetBytes(bytes); return BitConverter.ToInt32(bytes, 0); }
