Question

我的软件出现问题。它在标签中显示为json代码，但我使用Serialization将其转换为String，但它仍然以Json格式显示。此数据来自数据库。

using System;
using System.IO;
using System.Net;
using System.Windows;
using System.Web.Script.Serialization;




namespace MMPI2_Test

    }

    private void btyes_Click(object sender, RoutedEventArgs e)
    {

    }
    public String MyProperty { get; set; }

    public String Property { get; set; }
    private void MyWindow_Loaded(object sender, RoutedEventArgs e)
    {
        //dynamic convert = JsonConvert.DeserializeObject(MyProperty);

        string json = new JavaScriptSerializer().Serialize(MyProperty);
        lbuser.Content = json;


        string tan ="";
        MainWindow main = new MainWindow();
        main.alpha = tan;

        string html = string.Empty;
        string url = @"http://aa.workloud.at/?tag=question&token="+Property;

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.AutomaticDecompression = DecompressionMethods.GZip;

        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())

Answer 1

使用结构很适合json序列化。

public String MyProperty { get; set; }

public String Property { get; set; }
[Serializable]
public struct MyStuff
{
        public string MyProperty;

}

private void MyWindow_Loaded(object sender, RoutedEventArgs e)
{
    MyStuff stuff = new MyStuff();
    stuff.MyProperty = MyProperty;
    String json= JsonConvert.SerializeObject(stuff);

    lbuser.Content = json;

Answer 2

您的代码正在按照您的要求行事;将字符串（而不是HTML）转换为JSON对象，然后将lbuser.Content设置为该JSON。

如果您尝试从JSON中提取元素，则需要执行相反的操作;从JSON中提取字符串。 JSON.NET可能是最简单的方法，但如果您必须使用System.Web.Script.Serialization，则可以执行此操作：

var j = new System.Web.Script.Serialization.JavaScriptSerializer().DeserializeObject(html) as Dictionary<string, object>;
var d = j["data"] as Dictionary<string, object>;
lbuser.Content = d["fname"].ToString();

请注意，您发布的JSON在语法上是不正确的，您甚至没有向我们展示内容，因此我完全猜测您的真实JSON中可用的键是什么。在调试器中检查其内容。

Answer 3

你想要达到什么目标？

private void MyWindow_Loaded(object sender, RoutedEventArgs e)
{
    //dynamic convert = JsonConvert.DeserializeObject(MyProperty);

    string json = new JavaScriptSerializer().Serialize(MyProperty);
    lbuser.Content = json;
}

使用javascript序列化程序（即创建JSON）对属性进行SERIALIZING，然后将json指定给lbuser.Content。

如果数据来自JSON，那么通常你会将它DESERIALIZE成一个镜像JSON属性的类或一个字典。

Json to String不起作用
