试图反序列化一个json文件C＃ [英] Trying to deserialize a json file C#

问题描述

你好，伙计们。我第一次问这里。所以，我有一种情况试图从Json文件中获取一些信息。我希望获得Public Class Valore和Resultados内部的信息。这就是我的代码的样子：

Hello, guys. My first time asking here. So, I got a situation trying to get some information from a Json File. I want to reach the information that is inside of the Public Class Valore and Resultados. This is how my code looks like:

public class Valore
        public string fecha { get; set; }
    {
    public string hora { get; set; }
    public string pml { get; set; }
    public string pml_ene { get; set; }
    public string pml_per { get; set; }
    public string pml_cng { get; set; }
}

public class Resultado
{
    public string clv_nodo { get; set; }
    public List<valore> Valores { get; set; }
}

public class RootObject
{
    public string nombre { get; set; }
    public string proceso { get; set; }
    public string sistema { get; set; }
    public string area { get; set; }
    public List<resultado> Resultados { get; set; }
    public string status { get; set; }
}



class Program
{
    static void Main(string[] args)
    {
        RootObject PrecioMarginal;
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(@"Someplaceoninternet");
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
        using (Stream stream = response.GetResponseStream())
        using (StreamReader reader = new StreamReader(stream))
        {
            string json = reader.ReadToEnd();
            price = JsonConvert.DeserializeObject<rootobject>(json);
           
        }
        Console.WriteLine("El estatus del nodo es: " + Price.status);
        Console.ReadKey();
    }
}

我的尝试：



不是太多，我第一次使用C＃编写代码

推荐答案

这个问题在这里有很多问题，所以我发表了一篇文章，回答了你的问题和其他问题：在C＃中使用JSON& VB [ ^ ]

This question gets asked a lot in here, so I published an article that answers yours and other questions: Working with JSON in C# & VB[^]

我强烈建议使用Newtonsoft.JSON进行反序列化：

I can strongly recommend using Newtonsoft.JSON for deserialization:

/// <summary>
/// Load all known sheets
/// </summary>
/// <param name="path">
/// Full path to the JSON file containing the sheet data.
/// If not provided, the default will be used.</param>
/// <returns></returns>
public static List<AveryLabelSheet> Load(string path = null)
    {
    if (path == null) path = GetSensiblePathToSheetDataFile();
    if (!File.Exists(path)) throw new FileNotFoundException("Cannot locate the Sheet Data file:\n   \"" + path + "\"\nPlease check the path and try again.");
    try
        {
        all = JsonConvert.DeserializeObject<List<AveryLabelSheet>>(File.ReadAllText(path));
        }
    catch (Exception ex)
        {
        throw new FileLoadException("Unable to load Sheet Data.\nThe file \"" + path + "\" does not load correctly.", ex);
        }
    isLoaded = true;
    return new List<AveryLabelSheet>(all);
    }

一行代码完成整个工作：

One line of code does the whole job:

all = JsonConvert.DeserializeObject<List<AveryLabelSheet>>

您需要安装Newtonsoft.JSON：您可以通过NuGet包管理器将其添加到您的项目中（工具... NuGet包管理器...包管理器控制台）：

You will need to install Newtonsoft.JSON: you can add it to your project via the NuGet Package Manager (Tools ... NuGet Package Manager ... Package Manager Console):

PM> Install-Package Newtonsoft.Json

顺便说一下，我第一次使用JSON数据和最近的prioject，并且使用Newtonsoft的东西非常容易：序列化并在每行代码中反序列化一个自定义类的完整列表！我发现的唯一麻烦是它只有在相关的类属性同时具有公共getter和setter时才有效 - 我最初使用私有setter，数据无法回读，这是可以理解的。

As an aside, I'm using JSON data for the first time with a recent prioject, and it's remarkably easy with the Newtonsoft stuff: serialize and deserialize a whole list of a custom class in one line of code each! The only hassle I found was it only works if the relevant class properties have both public getter and setter - I originally used private setters, and the data failed to read back, understandably.
