我制作了一个图像类，用于从维基百科api下载图像。我制作了3个功能，在3个图片框中显示3个图像。我使用＆＃34; thumburl＆＃34;来自json wiki api的图片链接。这是我的图像类代码。
class Images
{
public static PictureBox Image1 = new PictureBox();
public static PictureBox Image2 = new PictureBox();
public static PictureBox Image3 = new PictureBox();
public static Label Image1_title = new Label();
public static Label Image2_title = new Label();
public static Label Image3_title = new Label();
public static void Load_Image1(string name, string id,string LocationName)
{
string Jpeg = Path.Combine(Environment.CurrentDirectory, @"C:\C# tutorial Backup\Tourist_Place\Images\"+LocationName);
using (WebClient wc = new WebClient())
{
var client = new WebClient();
var uri = ("https://en.wikipedia.org/w/api.php?action=query&prop=imageinfo&iiprop=comment|url|dimensions&format=json&iiurlwidth=400&titles=" + name);
var response = client.DownloadString(new Uri(uri));
JObject obj = JObject.Parse(response);
string image1 = (string)obj["query"]["pages"][id]["imageinfo"][0]["thumburl"];
Image1.SizeMode = PictureBoxSizeMode.StretchImage;
Image1.LoadAsync(image1);
string image1_Title = (string)obj["query"]["pages"][id]["title"];
Image1_title.Text = image1_Title;
var hash = uri.GetHashCode();
var path = Path.Combine(Jpeg, hash.ToString("X") + ".jpg");
client.DownloadFile(image1, path);
}
}
public static void Load_Image2(string name, string id,string LocationName)
{
string Jpeg = Path.Combine(Environment.CurrentDirectory, @"C:\C# tutorial Backup\Tourist_Place\Images\" + LocationName);
using (WebClient wc = new WebClient())
{
var client = new WebClient();
var uri = ("https://en.wikipedia.org/w/api.php?action=query&prop=imageinfo&iiprop=comment|url|dimensions&format=json&iiurlwidth=400&titles=" + name);
var response = client.DownloadString(new Uri(uri));
JObject obj = JObject.Parse(response);
string image2 = (string)obj["query"]["pages"][id]["imageinfo"][0]["thumburl"];
Image2.SizeMode = PictureBoxSizeMode.StretchImage;
Image2.LoadAsync(image2);
string image2_Title = (string)obj["query"]["pages"][id]["title"];
Image2_title.Text = image2_Title;
var hash = uri.GetHashCode();
var path = Path.Combine(Jpeg, hash.ToString("X") + ".jpg");
client.DownloadFile(image2, path);
}
}
public static void Load_Image3(string name, string id, string LocationName)
{
//string fileName = name + ".jpg";//plaese change the storage location
string Jpeg = Path.Combine(Environment.CurrentDirectory, @"C:\C# tutorial Backup\Tourist_Place\Images\"+ LocationName);
using (WebClient wc = new WebClient())
{
var client = new WebClient();
var uri = ("https://en.wikipedia.org/w/api.php?action=query&prop=imageinfo&iiprop=comment|url|dimensions&format=json&iiurlwidth=400&titles=" + name);
var response = client.DownloadString(new Uri(uri));
JObject obj = JObject.Parse(response);
string image3 = (string)obj["query"]["pages"][id]["imageinfo"][0]["thumburl"];
Image3.SizeMode = PictureBoxSizeMode.StretchImage;
Image3.LoadAsync(image3);//
string image3_Title = (string)obj["query"]["pages"][id]["title"];
Image3_title.Text = image3_Title;
var hash = uri.GetHashCode();
var path = Path.Combine(Jpeg, hash.ToString("X") + ".jpg");
client.DownloadFile(image3, path);
}
}
}
}
现在在form.cs中我用函数调用这个类，并手动输入所有图像，名称和id的值。这是我的form1.cs
namespace Wikipedia_Image_Text_24_11_2015
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
POI_List.Combo_list = comboBox1;
POI_List.List();
}
public void Download_Click(object sender, EventArgs e)
{
Images.Image1 = pictureBox1;
Images.Image2 = pictureBox2;
Images.Image3 = pictureBox3;
Images.Image1_title = label1;
Images.Image2_title = label2;
Images.Image3_title = label3;
switch (comboBox1.Text)
{
case "Heidelberg Castle":
Images.Load_Image1("File:Heidelberg-Schlo%C3%9F.JPG", "-1", "Heidelberg Castle");
Images.Load_Image2("File:Heidelberg%2020060420%20021.jpg", "-1", "Heidelberg Castle");
Images.Load_Image3("File:Rondell%20Heidelberger%20Schloss%20vom%20Stueckgarten.jpg", "-1", "Heidelberg Castle");
break;
case "Neuschwanstein Castle":
Images.Load_Image1("File:Schloss%20Neuschwanstein%202013.jpg", "40677196", "Neuschwanstein Castle");
Images.Load_Image2("File:Neuschwanstein%20castle.jpg", "-1", "Neuschwanstein Castle");
Images.Load_Image3("File:Hohenschwangau_-_Schloss_Neuschwanstein5.jpg", "-1", "Neuschwanstein Castle");
break;
我知道应该有更短的方法来简化编码。我尝试了很多。但是失败了。如果有人回答我应该做些什么来使它更通用或更具动态
，那就太好了答案 0 :(得分：1)
您的问题是减少服务电话的数量。根据维基百科[沙箱文档] [1]
[1]：https://en.wikipedia.org/wiki/Special:ApiSandbox#action=query&prop=imageinfo&format=json&titles=File%3ANeuschwanstein%20castle.jpg%7CFile%3AHohenschwangau_-_Schloss_Neuschwanstein5.jpg
它接受请求中的文件（标题）以外的内容。所以只需打一个REST电话。您将获得一系列页面。解析它。循环遍历数组并显示图像。您不需要3个单独的方法
