C#按固定字符长度分割成数列

Question

求用C#,按固定字符长度【中文要计2个】，拆分字符成List。如将字符【712中国人，TSDTS我ES】，每隔4位分割。结果为{"712","中国"，"人，"，"TSDT","S我"，"ES"} 解释：前面3位是因为第4个字符是中文的一半，只能取3位。很头痛，麻烦帮忙。

using System;
using System.Collections.Generic;

class Program
{
    static void Main(string[] args)
    {
        string str = "712中国人，TSDTS我ES";
        int maxLength = 4;

        List<string> result = SplitString(str, maxLength);
        foreach (string s in result)
        {
            Console.WriteLine(s);
        }
    }

    static List<string> SplitString(string str, int maxLength)
    {
        List<string> result = new List<string>();
        int length = 0;
        string temp = "";

        foreach (char c in str)
        {
            length += GetCharLength(c);

            if (length <= maxLength)
            {
                temp += c;
            }
            else
            {
                result.Add(temp);
                temp = c.ToString();
                length = GetCharLength(c);
            }
        }

        if (!string.IsNullOrEmpty(temp))
        {
            result.Add(temp);
        }

        return result;
    }

    static int GetCharLength(char c)
    {
        int length = 0;
        if (c > 127)
        {
            length = 2;
        }
        else
        {
            length = 1;
        }
        return length;
    }
}
