比较字符串

例子，当遇到A1 A10 A2 order by 不起作用了

需要自己写

public class StringCompare<T> : IComparer<T> where T : T_TempActicle
    {
        //比较两个字符串，如果含用数字，则数字按数字的大小来比较。
        int IComparer<T>.Compare(T x, T y)
        {
            if (x == null || y == null)
                throw new ArgumentException("Parameters can't be null");
            string fileA = x.Title as string;
            string fileB = y.Title as string;
            char[] arr1 = fileA.ToCharArray();
            char[] arr2 = fileB.ToCharArray();
            int i = 0, j = 0;
            while (i < arr1.Length && j < arr2.Length)
            {
                if (char.IsDigit(arr1[i]) && char.IsDigit(arr2[j]))
                {
                    string s1 = "", s2 = "";
                    while (i < arr1.Length && char.IsDigit(arr1[i]))
                    {
                        s1 += arr1[i];
                        i++;
                    }

                    {
                        s2 += arr2[j];

                    }
