C#获取本地txt文件后Json的解析与取值

1、添加引用Newtonsoft.Json.dll

using Newtonsoft.Json.Linq;

2、具体代码：

StreamReader sr = new StreamReader("D:\\" + "****" + ".txt");
String data = sr.ReadToEnd();
 //data ="{\r\n\t\"Data\": [{\r\n\t\t\t\"dwdm\": \"1020031077\"\r\n\t\t},\r\n\t\t{\r\n\t\t\t\"dwdm\": \"1020120426\"\r\n\t\t}]\r\n}"
            data = data.Replace("\r", string.Empty).Replace("\n", string.Empty).Replace("\t", string.Empty);//去除空格
            JObject studentsJson = JObject.Parse(data);
            var studentsList = studentsJson["Data"].AsEnumerable();
            string a = "";
            foreach (var item in studentsList)
            {
                 a = item["dwdm"].ToString();
            }
            return a;
