一个字符串转换成数组5个一组

protected void Page_Load(object sender, EventArgs e)
    {

        string sql = "a|b|c|d|  |  |e|f|g|h|i|j|k";
        System.Text.RegularExpressions.Regex ze = new System.Text.RegularExpressions.Regex("\\s");
        sql= ze.Replace(sql,"");
        System.Text.RegularExpressions.Regex ze1 = new System.Text.RegularExpressions.Regex("|");
        sql = ze.Replace(sql, "|");
        string[] dd = { "|" };
        string[] aa = sql.Split(dd, StringSplitOptions.RemoveEmptyEntries);
        
        int len = aa.Length;
        int x2=0;
        if(len%5==0)
        {
            x2=len/5;
        }
        else

        for (int i = 0; i < len; i++)

            if (i != 0 && i % 5 == 0)
            {
                x += 1;
            }
            l[x] += aa[i] + ",";
