这就是我到目前为止所拥有的.我试图从URL读取XML,并获得例如温度,湿度......等等.但每次我尝试别的东西它都会给我一个错误.我想检索信息并将其放在标签中.

namespace WindowsFormsApplication1 {
    public partial class Form1: Form {
        public Form1() {
            InitializeComponent();
        }
        private void btnSubmit_Click(object sender, EventArgs e) {
            String zip = txtZip.Text;
            XmlDocument weatherURL = new XmlDocument();
            weatherURL.Load("http://api.wunderground.com/api/"
            your_key "/conditions/q/" + zip + ".xml");
            foreach(XmlNode nodeselect in weatherURL.SelectNodes("response/current_observation"));
        }
    }
}
