linq排序之 根据文本 A-001-002-003 这种类型进行分割排序 空值放于最后

调用

  List<string> data = new List<string>() {
                "D-001-001-001","A-001-004-001","A-001-002-001",
                "A-002-001-001", "F-004-001-001", "A-003-001-001",
                "A-004-001-004","A-041-0401-031","" };
            var gf = (from e in data select e).OrderBy(x => x, new AlphaNumericComparer()).ToList();

比较器

  public class AlphaNumericComparer : IComparer<string>
    {
        public int Compare(string first, string second)
        {
             int firstNumber, secondNumber;//定义数值类型返回值
            if (string.IsNullOrEmpty(first)&& string.IsNullOrEmpty(second))
            {
                return 0;
            }
            if (string.IsNullOrEmpty(first) && !string.IsNullOrEmpty(second))
            {
                return 1;
            }
            if (!string.IsNullOrEmpty(first) && string.IsNullOrEmpty(second))
            {
                return -1;
            }
            //分割字符串
            string[] firstArray = first.Split('-');
            string[] secondArray = second.Split('-');
            List<int> intArray = new List<int>();
            //记录比较结果
            for (int i = 0; i < firstArray.Length; i++)
            {
                bool firstIsNumber = int.TryParse(firstArray[i], out firstNumber);
                bool secondIsNumber = int.TryParse(secondArray[i], out secondNumber);
                if (firstIsNumber && secondIsNumber)
                {
                    //数字比较
                    intArray.Add(firstNumber.CompareTo(secondNumber));
                }
                else {
                    //文本比较
                    intArray.Add(firstArray[i].CompareTo(secondArray[i]));
                }
            }
            intArray.Reverse();//从末位开始计算差值
            int val = 0;
            //获取差值占比
            for (int i = 0; i < intArray.Count; i++)
            {
                val += intArray[i] * (i+1) * 10;
            }
            return val;
        }
    }
