提取字符串中的数据，判断数字是否为连续递增

规则 :      1,2,3,4,5,6,7,8  正确
1,1,3,4,5,6,7,8  错误 （缺2 是不连续的数字集）
1,4,2,3,5,5,6,7  正确


请看实现的代码：

/// <summary>
         /// 传入的值是否是连续的数字（可重复，但必须是连续的数字）

         /// </summary>

         /// <param name="str">1,2,3,4,5,6</param>

         /// <returns></returns>

         public static bool GetStrOrder(string str)

         {

            string[] arry = str.Split(',');

             int[] intArray = Array.ConvertAll<string, int>(arry, s => int.Parse(s));

             intArray = intArray.Distinct().OrderByDescending(x => x).ToArray();



             string StrChk = "";

             int Min = intArray.Last();

             int Max = intArray.First();

             for (int i = Min; i <= Max; i++)

             {

                 StrChk += "," + i;

             }

             StrChk = StrChk.Substring(1, StrChk.Length - 1);



            string[] arryChk = StrChk.Split(',');

             int[] intArryChk = Array.ConvertAll<string, int>(arryChk, s => int.Parse(s));

             intArryChk = intArryChk.OrderByDescending(x => x).ToArray();



             if (intArray.SequenceEqual(intArryChk))

             {

                 return true;

             }



             return false;

         }
