Get two results from another method in the the main application class using c#

Question

I am trying to write a c# code by which I want to get a image from web api and the title of the image from the api. I implemented a method named GetImage and try to return two results (image and title) from it. However I wrote a code but as I am new handling this situation,I do not know what to do in this case.

My Image service class which contain the methods is-

public class ImageService
{
    public string GetImage(string name)
    {                
        string result1;
        string result2;

        using (WebClient client = new WebClient())
        {
            var uri = "https://en.wikipedia.org/w/api.php?action=query&format=json&prop=pageimages&pithumbsize=400&titles="+name;
            string requestUrl = string.Format(uri, name);
            var response = client.DownloadString(new Uri(uri));
            var responseJson = JsonConvert.DeserializeObject<ImgRootobject>(response);
            var firstKey = responseJson.query.pages.First().Key;
            result1 = responseJson.query.pages[firstKey].thumbnail.source;
            result2 = responseJson.query.pages[firstKey].title;

            var hash = uri.GetHashCode();

        }
        return result1,result2; //showing error
    }
}

Now the Form1.cs where i want to show results in picturebox and label is-

public partial class Form1 : Form
{
    private readonly ImageService _imageService;
    public Form1()
    {            
        _imageService = new ImageService();
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
        pictureBox1.LoadAsync(_imageService.GetImage(textBox1.Text));
        label1.Text = _imageService.GetImage(textBox1.Text);// not working
    }
}

Answer 1

The best method is to create a new class that holds the details you need and return that. That way, if you need to add more information, you can just add it to the class.

For example:

public class ImageInfo
{
    public string Title { get; set; }
    public string Image { get; set; }
}

Then your method returns the class:

public ImageInfo GetImage(string name)
{                
    ImageInfo info = new ImageInfo();

    using (WebClient client = new WebClient())
    {
        var uri = "https://en.wikipedia.org/w/api.php?action=query&format=json&prop=pageimages&pithumbsize=400&titles="+name;
        string requestUrl = string.Format(uri, name);
        var response = client.DownloadString(new Uri(uri));
        var responseJson = JsonConvert.DeserializeObject<ImgRootobject>(response);
        var firstKey = responseJson.query.pages.First().Key;
        info.Image = responseJson.query.pages[firstKey].thumbnail.source;
        info.Title = responseJson.query.pages[firstKey].title;

        var hash = uri.GetHashCode();

    }
    return info;
}
