C#獲取本地txt文件後Json的解析與取值

1、添加引用Newtonsoft.Json.dll

using Newtonsoft.Json.Linq;

2、具體代碼：

 1 StreamReader sr = new StreamReader("D:\\" + "****" + ".txt");
 2 String data = sr.ReadToEnd();
 3  //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}"
 4             data = data.Replace("\r", string.Empty).Replace("\n", string.Empty).Replace("\t", string.Empty);//去除空格
 5             JObject studentsJson = JObject.Parse(data);
 6             var studentsList = studentsJson["Data"].AsEnumerable();
 7             string a = "";
 8             foreach (var item in studentsList)
 9             {
10                  a = item["dwdm"].ToString();
11             }
12             return a;
