Json格式字符串 如何转化成集合_javascriptserializer.deserialize(jsonst

今天做项目遇到个问题，需要把json字符串转化list集合进行操作，
在网上搜了很多资料
比如
需要引用命名空间
using Newtonsoft.Json;
System.Web.Extensions.dll

public DataTable JsonTdb(string strJson)
{
DataTable dataTable = new DataTable(); //实例化
DataTable result;
try
{

                JavaScriptSerializer javaScriptSerializer = new JavaScriptSerializer();    //引用System.Web.Extensions
                javaScriptSerializer.MaxJsonLength = Int32.MaxValue; //取得最大数值
                ArrayList arrayList = javaScriptSerializer.Deserialize<ArrayList>(strJson);
                if (arrayList.Count > 0)
                {
                    foreach (Dictionary<string, object> dictionary in arrayList)
                    {
                        if (dictionary.Keys.Count<string>() == 0)
                        {
                            result = dataTable;
                            // return result;
                        }
                        if (dataTable.Columns.Count == 0)
                        {
                            foreach (string current in dictionary.Keys)
                            {
                                dataTable.Columns.Add(current, dictionary[current].GetType());
                            }
                        }
                        DataRow dataRow = dataTable.NewRow();
                        foreach (string current in dictionary.Keys)
                        {
                            dataRow[current] = dictionary[current];
                        }

                        dataTable.Rows.Add(dataRow); //循环添加行到DataTable中
                    }
                }
            }
            catch
            {
            }
          return   dataTable;
            // return result;
        }

public static DataTable jsonTable(string json)
{

    return JsonConvert.DeserializeObject<DataTable>(json);
}

这二个主要针对于 简单josn格式 遇到嵌套的就会报异常
推荐用这个
需要引入命令空间
using Newtonsoft.Json.Linq;
JObject jobj = JObject.Parse(str);
这里填 你的data
JArray jar = JArray.Parse(jobj[“department”].ToString());

        for (int i = 0; i < jar.Count; i++)
        {

            if (jar[i]["name"] == DeptName)
            {

                dingID = Convert.ToInt32(jar[i]["Id"]);
            }


        }
