分享C#原生ID（流水号）生成功能实现

  /// <summary>
    ///

    public static class DataBaseGenerator
    {
        /// <summary>
        ///
        /// </summary>
        private static Int64 seed = Int64.Parse(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalMilliseconds.ToString("0"));

        /// <summary>

        /// <returns></returns>
        public static Int64 GetPrimaryKey()
        {
            return Interlocked.Increment(ref seed);
        }
    }

 

 

 

这个不错，把我的也供献一下
private static object IdLock = new object();
        /// <summary>
        /// 返回16位时间戳字符
/// </summary>
        public static string GetNewId()
        {
            string newid = "";
            lock (IdLock)
            {
                Thread.Sleep(1);
                newid = System.DateTime.Now.ToString("yyMMddHHmmssffff");
            }
在win2003中，Thread.Sleep(15)，系统问题，没办法到1
            return newid;
        }
