• 自己总结的,输出到前端JSON的几种方法


    第一种:利用MODEL拼成要输出JSON的对象。再用JSON.NET转成JSON输出到前端(这种常用,就不举例了。)

    第二种:利用table拼成JSON数据格式,再用JSON.NET转成JSON输出到前端

              

      dt = new DataTable();
    
                dt.Columns.Add(new DataColumn("列头",typeof(string)));
                dt.Columns.Add(new DataColumn("object", typeof(object)));
    
                DataRow dr = dt.NewRow();
                dr[0] = "abc";
                
                DataTable dt2 = dt.Clone();
                dt2.Columns.Add("defaultdata", typeof(string));
                DataRow dr2 = dt2.NewRow();
                dr2[0] = "defgijk";
                dr2["defaultdata"] = "cccc";
                dt2.Rows.Add(dr2);
                
                dr[1] = dt2;
    
                dt.Rows.Add(dr);
    
                GridView1.DataSource = dt.Rows[0][1];
                GridView1.DataBind();
    
                Label1.Text = JsonConvert.SerializeObject(dt);

    第三种:用JSON.net自带的JOBJECT,拼成JSON格式,转成JSON在前端输出:

        

    JObject obj = new JObject();
        obj.Add(new JProperty("Status", "S"));
        obj.Add(new JProperty("TotalCount", totalCount));
        JArray array = new JArray();
        if (result != null)
        {
        foreach (var item in result)
        {    
        array.Add(
        new JObject(
        new JProperty("X", item.X)
        , new JProperty(" XX", item.XX)
        , new JProperty("XXX", item.XXX)
        , new JProperty("Xxxxx", item.XXXX)
        , new JProperty("xxxxxxx", item.XXXXX)
        , new JProperty("xxxxxxxxx", item.XXXXXX)
        , new JProperty("xxxxxxxxxxx", item.XXXXXXX)
        , new JProperty("xxxxxxxxxxxxx", item.XXXXXXXX)
        , new JProperty("xxxxxxxxxxxxxxxxx", item.XXXXXXXXX)
        , new JProperty("xxxxxxxxxxxxxxxxxxxx", item.XXXXXXXXXX)
        , new JProperty("xxxxxxxxxxxxxxxxxxxxxxx", item.XXXXXXXXXXX)));
        }
        obj.Add(new JProperty("WorkOrderManagerList", array));
        Response.Write(JsonConvert.SerializeObject(obj));

     第四种:利用array数组和hashtable拼成JSON格式,转成JSON在前端输出:

        

     ArrayList eventList = new ArrayList();
    
         Hashtable hx = new Hashtable();
         hx.Add("eventid", 1);
              hx.Add("eventname", "圣诞节");
           hx.Add("eventdate", "2018-08-25");
           hx.Add("eventlocation", "公司会议中心");
    
           for (int i = 0; i < 3; i++)
          {
          Hashtable ht = new Hashtable();
          ht.Add("eventid", i + 1);
          ht.Add("eventname", "圣诞节");
          ht.Add("eventdate", hx);
          ht.Add("eventlocation", "公司会议中心");
          eventList.Add(ht);
         }
        JavaScriptSerializer ser = new JavaScriptSerializer();
        String jsonStr = ser.Serialize(eventList);
        Response.Write(jsonStr);
