ArrayList 与 String[] 之间的转换

 // 将String[]类型的数据转换成ArrayList类型
    public static String[] getStrings(ArrayList arrayList)
    {
        String[] record = new String[arrayList.size()];
        arrayList.toArray(record);
        return record;
    }

 

 

// 将String[]类型的数据转换成list类型
        public ArrayList toArrayList(string[] productIDs)
        {
            ArrayList list = new ArrayList();
            for (int i = 0; i < productIDs.Length; i++)
            {
                if ((null != productIDs[i] || "".Equals(productIDs[i])))
                {
                    list.Add(productIDs[i]);
                }
            }
            return list;
        }
