关于json序列化相关代码

自己写的一个

    /// <summary>
    /// 序列化JSON,返回string
    /// </summary>
    /// <param name="dt">传入DataTable</param>
    /// <param name="DateFormat">关于日期的格式,支持(yyyy-MM-dd)等</param>
    /// <returns></returns>
    private string SerializeJson(DataTable dt, string DateFormat)
    {
        List<Dictionary<string, object>> list = new List<Dictionary<string, object>>();
        foreach (DataRow row in dt.Rows)
        {
            Dictionary<string, object> dict = new Dictionary<string, object>();
            foreach (DataColumn col in dt.Columns)
            {
                dict[col.ColumnName] = row[col];
            }
            list.Add(dict);
        }
        JavaScriptSerializer jss = new JavaScriptSerializer();
        string jsonstr = jss.Serialize(list);
        jsonstr = Regex.Replace(jsonstr, @"\/Date((d+))\/", match =>
        {
            DateTime adt = new DateTime(1970, 1, 1);
            adt = adt.AddMilliseconds(long.Parse(match.Groups[1].Value));
            adt = adt.ToLocalTime();
            return adt.ToString(DateFormat);
        });
        return jsonstr;
    }

关于Newtonsoft.Json的使用方法

JObject obj = JObject.Parse(data);//序列化json对象
string openid = obj["openid"].ToString();
