csharp C#数字字符串排序orderby的问题解决

一般情况下您使用

strs.OrderBy(n=>n) 得出的结论是 1， 11,111,2，22,222
想要得出 1,2,11,22,111,222 咋办？
源码送上

static void Main()
{
    SemiNumericComparer comp = new SemiNumericComparer();

    List<string> strs = new List<string>(){"11", "12", "1:"};
    foreach(string str in strs.OrderBy(n => n, comp))
        Console.writeLine(str);
}

public class SemiNumericComparer : IComparer<string>
        {
            public int Compare(string s1, string s2)
            {
                if (IsNumeric(s1) && IsNumeric(s2))
                {
                    if (Convert.ToInt32(s1) > Convert.ToInt32(s2)) return 1;
                    if (Convert.ToInt32(s1) < Convert.ToInt32(s2)) return -1;
                    if (Convert.ToInt32(s1) == Convert.ToInt32(s2)) return 0;
                }
 
                if (IsNumeric(s1) && !IsNumeric(s2))
                    return -1;
 
                if (!IsNumeric(s1) && IsNumeric(s2))
                    return 1;
 
                return string.Compare(s1, s2, true);
            }
 
            public static bool IsNumeric(object value)
            {
                try
                {
                    int i = Convert.ToInt32(value.ToString());
                    return true;
                }
                catch (FormatException)
                {
                    return false;
                }
            }
        }
