问题描述

我希望我的Hero类中的一个属性具有用于其图像的Portrait属性.在这种情况下应该使用哪种对象类型?

I want a attribute in my Hero class to have a Portrait attribute for his/her image. What object type should I use in this case?

public class Hero
{
    public string Name { get; set; }
    public string HeroType { get; set; }
    public int StartingHP { get; set; }
    public int StartingMana { get; set; }
    public Dictionary<string, string> Spells { get; set; }
    public Dictionary<string, string> Items { get; set; }        
}

推荐答案

在WPF中，您应该使用

In WPF, you should use the ImageSource class, like this:

public class Hero {
    public string Name { get; set; }
    public string HeroType { get; set; }
    public int StartingHP { get; set; }
    public int StartingMana { get; set; }
    public Dictionary<string, string> Spells { get; set; }
    public Dictionary<string, string> Items { get; set; } 
    public ImageSource Portrait { get; set; }
}

您可以从这样的文件中读取图像:

You can read an image from a file like this:

myHero.Portrait = new BitmapImage(new Uri(filePath, UriKind.Absolute));

您可以使用 Image System.Drawing.dll中的类.例如:

You can use the Image class from System.Drawing.dll. For example:

public class Hero {
    public string Name { get; set; }
    public string HeroType { get; set; }
    public int StartingHP { get; set; }
    public int StartingMana { get; set; }
    public Dictionary<string, string> Spells { get; set; }
    public Dictionary<string, string> Items { get; set; } 
    public Image Portrait { get; set; }
}

要加载图像，请调用Image.FromFile(path).如果流中有图像(例如，来自数据库或Web服务的图像)，则可以调用Image.FromStream(stream).

To load the image, call Image.FromFile(path). If you have an image in a stream (eg, from a database or web service, you can call Image.FromStream(stream).

如果在编译时拥有所有图像，则可以将它们放在ResX文件中；否则，可以将它们放置在ResX文件中.您可以从设计师生成的代码文件中获取图像，如下所示:myHero.Portrait = SomeResXFile.Portrait1.

If you have all of the images at compile time, you can put them in a ResX file; you can get an image from the designer-generated code file like this: myHero.Portrait = SomeResXFile.Portrait1.
