--资源图片加载
--直接绑定资源图片文件路径，图片不能正常加载，因为 Image Source 绑定需要 Avalonia.Media.IImage 类型数据，需要将资源图片转BitMap 后绑定，需要在函数中通过AssetLoader 获取资源文件后转为BitMap

    this.Title = Title;this.Tag = Tag;this.Tips = Tips;this.Enable = Enable;// 使用 AssetLoader 从嵌入资源加载 Bitmapvar uri = new Uri(Icon);using (var stream = AssetLoader.Open(uri)){this.Icon = new Bitmap(stream);}
