Question

我的json看起来像：

[
  {
     fid: "1",
     forum_name: "Latest Product News",
     imagepath: "http://sourcingmachine.co.uk/iphone_images/news_icons/product-news.png"
  },
  {
     fid: "19",
     forum_name: "Latest Supplier News",
     imagepath: "http://sourcingmachine.co.uk/iphone_images/news_icons/supplier-news.png"
  }
]

如何在列表框中获取此数据？

我现在已经这样做了：

public MainPage()
{
    InitializeComponent();

    WebClient webclient = new WebClient();
    webclient.DownloadStringCompleted += webclient_DownloadStringCompleted;
    webclient.DownloadStringAsync(new Uri("MyURI"));
}

private void webclient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
    if (!string.IsNullOrEmpty(e.Result))
    {
        var rootObject = JsonConvert.DeserializeObject<RootObject>(data);
        this.DataContext = rootObject;
    }
}

这是我的RootObject类

public class RootObject
{
    [JsonProperty(PropertyName = "fid")]
    public string fid { get; set; }

    [JsonProperty(PropertyName = "forum_name")]
    public string forum_name { get; set; }

    [JsonProperty(PropertyName = "imagepath")]
    public string imagepath { get; set; }
}

如何将结果分配给我的ListBox.ItemSource？

Answer 1

public class YourModelObject
{
    public int fid { get;set; }
    public string forum_name { get;set; }
    public string imagepath { get;set; }
}

从JSON字符串调用转换时

string yourJSON = "what you posted above";
var values = JsonConvert.DeserializeObject<List<RootObject>>(yourJSON);
//values is a List<RootObject> if it succeds

Answer 2

InitializeComponent();

WebClient webclient = new WebClient();

webclient.DownloadStringCompleted += webclient_DownloadStringCompleted;
webclient.DownloadStringAsync(new Uri("Your URI"));

private void webclient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{

    try
    { 
        string data = e.Result;
        if (!string.IsNullOrEmpty(data))
        {
            var rootObject = JsonConvert.DeserializeObject<List<GetNews>>(data);
            lstNews.ItemsSource = rootObject;
        }                
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
}

GetNews

class GetNews
{
    public string fid { get; set; }
    public string forum_name { get; set; }
    public string imagepath { get; set; }
}
