我怎样才能在课堂上有一个属性来存储图片/图像？

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?

我想在我的Hero类中有一个属性为他/她的图像设置一个Portrait属性。在这种情况下我应该使用什么对象类型？

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; }        
}

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

在WPF中，您应该使用ImageSource类，如下所示：

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; }
}

You can read an image from a file like this:

您可以从这样的文件中读取图像：

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

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

您可以使用System.Drawing.dll中的Image类。例如：

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; } }

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).

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，则可以调用Image.FromStream（stream）。

~~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.~~

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

Beware the memory hogging some of the other answers may lead to. This is a data object right, not a UI object?

当心内存占用其他一些答案可能会导致。这是一个数据对象权限，而不是UI对象？

Do you know for a fact that you will always need the image for the life of the object? I would be concerned about eating up memory. It's probably better to just keep a resource identifier (file path, name in resource file, etc) and only pass that info on to image boxes. I wouldn't suggest holding on to the whole image. In winforms at least (don't know about WPF) the garbage collector isn't so hot at cleaning up images. It only sees them as a reference (i.e. an integer) because the rest of the image is basically an unmanaged object and thinks it's not a high priority for collection. Meanwhile, it could be chewing up megabytes. We got burned on a previous project of mine on that.

你是否知道一个事实，你将始终需要图像的对象的生命？我会担心吃掉记忆力。最好只保留资源标识符（文件路径，资源文件中的名称等），并仅将该信息传递给图像框。我不建议坚持整个形象。至少在winforms中（不了解WPF）垃圾收集器在清理图像方面不是那么热门。它只将它们视为参考（即整数），因为图像的其余部分基本上是一个非托管对象，并认为它不是收集的高优先级。与此同时，它可能正在咀嚼兆字节。我们之前的一个项目被烧毁了。
