c# json解析 如何得到text内容 要具体代码

{"result" : "ok","tuc" : [ {"authors" : [ 13 ],"meaningId" : 2397164096556578585,"phrase" : {"text" : "机场","language" : "zho" }},{"authors" : [ 3266 ],"meaningId" : 1269040436618011315,"phrase" : {"text" : "机场","language" : "zho"}}]

Answer 1

你肯定已经装了json.NET是吧？

 

 

然后你这个字符串存成info.json文件，读取代码如下：

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
namespace jsonproject
{
    class Program
    {
        static void Main(string[] args)
        {
            using (StreamReader reader = File.OpenText("info.json"))
            {
                JObject oText = (JObject)JToken.ReadFrom(new JsonTextReader(reader));
                var contents =
                    from p in oText["tuc"]
                    select (string)p["phrase"]["text"];

                foreach (var item in contents)
                {
                    Console.WriteLine(item);
                }
                System.Console.ReadKey();
            }
        }
    }
}

基本成功了，汉字不识别有乱码

追答

文件要存成UTF-8格式。

这是WinForm项目，源中的\u52c7\u6c14等要转换为中文。

Answer 3

您先定义一个实体来类
Att_Machine_RecordModel

[Serializable]
public partial class Att_Machine_RecordModel
{
public Att_Machine_RecordModel()
{ }
#region Model

/// <summary>
///
/// </summary>
public int PId=0;

/// <summary>
///
/// </summary>
public string AttCode= "";

/// <summary>
///
/// </summary>
public string CheckTime= "";

/// <summary>
///
/// </summary>
public string CheckType="";

/// <summary>
///
/// </summary>
public string LastModifyTime="";

/// <summary>
///
/// </summary>
public int MachineNum=0;

/// <summary>
///
/// </summary>
public string EntityState="";

/// <summary>
///
/// </summary>
public string EntityKey ="";

#endregion Model
}

然后把这段文字
string _JsonText = System.IO.File.ReadAllText(@"C:\inetpub\wwwroot\test\2014-08-151.txt");
List<Att_Machine_RecordModel> list = new List<Att_Machine_RecordModel>();
System.Runtime.Serialization.Json.DataContractJsonSerializer _Json = new System.Runtime.Serialization.Json.DataContractJsonSerializer(list.GetType());
byte[] _Using = System.Text.Encoding.UTF8.GetBytes(_JsonText);
System.IO.MemoryStream _MemoryStream = new System.IO.MemoryStream(_Using);
_MemoryStream.Position = 0;
list = (List<Att_Machine_RecordModel>)_Json.ReadObject(_MemoryStream);

foreach(var v in list)
{
AddAtt_Machine_Record(DefaultDBString, v);
}

追问

这是什么。。。

追答

我已经写了呀
list = (List)_Json.ReadObject(_MemoryStream);
就是转换成List，然后通过list的对象Att_Machine_RecordModel取值呀

追问

AddAtt_Machine_Record(DefaultDBString, v);出错了

追答

靠， list = (List)_Json.ReadObject(_MemoryStream);
就是您要的结果呀

Answer 4

准备数据
实体类：
[DataContract]
public class Person
{
[DataMember(Order = 0, IsRequired = true)]
public string Name { get; set; }

[DataMember(Order = 1)]
public int Age { get; set; }

[DataMember(Order = 2)]
public bool Alive { get; set; }

[DataMember(Order = 3)]
public string[] FavoriteFilms { get; set; }

[DataMember(Order = 4)]
public Person Child { get; set; }
}

定义：
Action<object> log = o => Console.WriteLine(o);
Func<int, int, int> add = (x, y) => x + y;

var p1 = new Person {
Age = 12,
Alive = true,
Name = "lj",
FavoriteFilms = new[] { "Up", "Avatar" }
};
var p2 = new Person() { Age = 28, Name = "cy", Child = p1 };
