我已经阅读了一段时间现在该怎么做，但我从来没有找到我理解或工作的芒果。

这是我的代码

namespace SongTunes
{
public partial class Form1 : Form
{
    Object Songs;

    public class Song
    {
        public int song_id { get { return song_id; } set { song_id = value; } }
        public string sorting_number { get; set; }
        public string name { get; set; }
        public string description { get; set; }
        public string lyrics { get; set; }
        public string purchase_link { get; set; }
        public string youtube_id { get; set; }
        public string has_music_video { get; set; }
        public string allow_downloads { get; set; }
        public string raw_artist_id { get; set; }
        public string artist_id { get; set; }
        public string album_artist_id { get; set; }
        public string release_date { get; set; }
        public string artist_name { get; set; }
        public string album_artist_name { get; set; }
        public string album { get; set; }
        public string bitrate { get; set; }
        public string duration { get; set; }
        public string filesize { get; set; }
        public string path { get; set; }
        public string is_part_of_compilation { get; set; }
        public string visible { get; set; }
        public string track_number { get; set; }
        public string is_explicit { get; set; }
    }

    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        button1.Enabled = false;
        button1.Text = "Loading...";
        backgroundWorker1.RunWorkerAsync();
    }

    private void Form1_Load(object sender, EventArgs e)
    {

    }

    private void backgroundWorker1_Done(object sender, RunWorkerCompletedEventArgs e)
    {
        button1.Enabled = true;
        button1.Text = "reload";
    }


    private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
    {
        string address = "";
        System.Net.WebClient webclient = new WebClient();
        string json = webclient.DownloadString(address);
        Songs = JsonConvert.DeserializeObject<List<Song>>(json);
    }

    private void SongList_SelectedIndexChanged(object sender, EventArgs e)
    {

    }
}
}

它只是在第一次

崩溃

public int song_id { get { return song_id; } set { song_id = value; } }

“在SongTunes.exe中发生了'System.StackOverflowException'类型的未处理异常”

Answer 1

 public int song_id { get { return song_id; } set { song_id = value; } }

get和引用它自己，这会在你调用它时导致堆栈溢出。如果要将值保存在字段中，请尝试：

 private int _song_id;
 public int song_id { get { return _song_id; } set { _song_id = value; } }

或只是将其更改为：

 public int song_id { get; set; }

与您的其他属性一样

Json中的StackOverflowException到Object / String []
