Question

我正在做一个天气API项目。即将到来的7天天气信息已在消息框中成功显示。

如何使用datagridview显示所有数据而不是消息框？

这是我目前的工作代码：

string uri = string.Format("http://api.apixu.com/v1/forecast.xml?key=keygoeshere&q={0}&days=7", city);
            XDocument doc = XDocument.Load(uri);
            foreach (var npc in doc.Descendants("forecastday"))
            {
               MessageBox.Show((string)npc.Descendants("date").FirstOrDefault());
               MessageBox.Show("Max temp " + (string)npc.Descendants("maxtemp_c").FirstOrDefault());
               MessageBox.Show("Min temp " + (string)npc.Descendants("mintemp_c").FirstOrDefault());
               MessageBox.Show("Text " + (string)npc.Descendants("text").FirstOrDefault());
               MessageBox.Show("Icon " + (string)npc.Descendants("http"+"icon").FirstOrDefault());

            }

将数据放入DataTable，然后将DataTable作为DGV的DataSource。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Xml;
using System.Xml.Linq;
using System.Net;
using System.IO;
namespace WindowsFormsApplication3
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();


            DataTable dt = new DataTable();
            dt.Columns.Add("Date", typeof(string));
            dt.Columns.Add("Max Temp", typeof(string));
            dt.Columns.Add("Min Temp", typeof(string));
            dt.Columns.Add("Text", typeof(string));
            dt.Columns.Add("Icon", typeof(Bitmap));

            string city = "London";


            string uri = string.Format("http://api.apixu.com/v1/forecast.xml?key=keygoeshere&q={0}&days=7", city);

            XDocument doc = XDocument.Load(uri);
            foreach (var npc in doc.Descendants("forecastday"))
            {
                string iconUri = (string)npc.Descendants("icon").FirstOrDefault();
                WebClient client = new WebClient();
                byte[] image = client.DownloadData("http:" + iconUri);
                MemoryStream stream = new MemoryStream(image);



                Bitmap newBitMap = new Bitmap(stream);
                dt.Rows.Add(new object[] {
                    (string)npc.Descendants("date").FirstOrDefault(),
                    (string)npc.Descendants("maxtemp_c").FirstOrDefault(),
                    (string)npc.Descendants("mintemp_c").FirstOrDefault(),
                    (string)npc.Descendants("text").FirstOrDefault(),
                    newBitMap
                });

            }
            dataGridView1.DataSource = dt;
        }
    }
}
