using System;
using System.Collections.Generic;

public class Kata
{
  public static string PrintArray(object[] array)
  {
   var list = new List<string>();
            foreach (var item in array)
            {
                var obj = item as object[];
                if (obj == null)
                {
                    list.Add(item.ToString());
                }
                else
                {
                    string temp = PrintArray(obj);
                    list.Add(temp);
                }
            }
            return string.Join(",", list);
  }
}

 

关于数组类型的判断，可以使用

a.GetType().IsArray
