请原谅我，如果我的问题需要进一步解释，因为我对编程很陌生。
我正在为Windows 10创建一个简单的食谱应用。我想做的是能够从食谱列表（按类别排序）中点击食谱，这将使用户进入食谱模板页面。根据选择的配方，模板页面将填写与该配方相关的信息（准备时间，成分，方向等）。
我有一个类似于
的类文件 public class Recipes
{
public string Name { get; set; }
public string Image { get; set; }
public string PrepTime { get; set; }
public string Ingredients { get; set; }
public string Description { get; set; }
public string Instructions { get; set; }
public string Category { get; set; }
public bool MainCourse { get; set; }
public int RecipeNumber { get; set; }
}
public class RecipeManager
{
public static List<Recipes> GetRecipes()
{
var recipes = new List<Recipes>();
recipes.Add(new Recipes { Name = "Chicken Parmesan", Image = "Assets/Chicken-Parm-2.jpg", Category = "Main Course", MainCourse = true});
recipes.Add(new Recipes { Name = "Eggplant Parmesan", Image = "Assets/eggplantparm.jpg", Category = "Main Course", MainCourse = true });
recipes.Add(new Recipes { Name = "Cookies", Image = "Assets/cookies.jpg", Category = "Desserts"});
recipes.Add(new Recipes { Name = "Salad", Image = "Assets/salad.jpg", Category = "Salad" });
recipes.Add(new Recipes { Name = "Zuccinni Chips", Image = "Assets/appetizers.jpg", Category = "Appetizers" });
recipes.Add(new Recipes { Name = "Meat Dish", Image = "Assets/maincourse.jpg", Category = "Main Course" });
recipes.Add(new Recipes { Name = "Classic Red Sauce", Image = "Assets/sauces.jpg", Category = "Sauces" });
recipes.Add(new Recipes { Name = "Casserole", Image = "Assets/vegan.jpg", Category = "Vegan Recipes" });
return recipes;
}
}
我的类别页面如下所示：
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="100" />
</Grid.RowDefinitions>
<GridView ItemsSource="{x:Bind Recipes}" IsItemClickEnabled="True" ItemClick="GridView_ItemClick">
<GridView.ItemTemplate>
<DataTemplate x:DataType="data:Recipes">
<RelativePanel>
<Image Width="150" Source="{x:Bind Image}" Tapped="Image_Tapped" ></Image>
<TextBlock FontSize="16" Text="{x:Bind Name}" ></TextBlock>
</RelativePanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
</Grid>
使用它后面的代码（这可能看起来很奇怪，因为我正在尝试一些使其工作的东西）：
public sealed partial class CategoryRecipes : Page
{
private List<Recipes> Recipes;
public CategoryRecipes()
{
this.InitializeComponent();
Recipes = RecipeManager.GetRecipes();
}
private void Image_Tapped(object sender, TappedRoutedEventArgs e)
{
Frame.Navigate(typeof(RecipePage));
}
private void GridView_ItemClick(object sender, ItemClickEventArgs e)
{
var recipe = (Recipes)e.ClickedItem;
Frame.Navigate(typeof(RecipePage));
}
}
现在，Recipe模板页面看起来像这样（我将硬编码数据作为占位符放入，因此我可以找出布局）：
<ScrollViewer VerticalScrollBarVisibility="Hidden">
<Frame>
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}" BorderBrush="{ThemeResource AppBarBorderThemeBrush}">

Reduce heat to medium and cook and stir for 2 minutes more. Season with salt and pepper. Add frozen peas and carrots and cooked chicken. Pour into prepared casserole dish.
In a medium bowl, mix together 2 cups flour, baking powder, and 3/4 teaspoon salt. Cut in shortening until mixture is crumbly. Stir in milk just until dough is moistened, then drop by spoonfuls onto chicken mixture.
Bake at 450 degrees F (230 degrees C) for 12 to 15 minutes, or until biscuits are golden brown, and cooked on the bottom. This tends to bubble over so I place a piece of aluminum foil under the pan to catch the drips." />

我现在非常迷失，不知道下一步该去哪儿。非常感谢您提供的任何指导。
更新：这可能是一个愚蠢的问题，但我添加了您的代码，然后将其添加到RecipePage中以调用配方的名称：
<GridView ItemsSource="{x:Bind Recipes}" Grid.Row="1">
<GridView.ItemTemplate>
<DataTemplate x:DataType="data:Recipes">
<RelativePanel>
<TextBlock FontSize="16" Text="{x:Bind Name}" ></TextBlock>
</RelativePanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
我收到错误 - 无效的绑定路径'Recipes'：在'RecipePage'类型上找不到属性'Recipes'。任何想法如何解决这一问题？我确定我做的事情很蠢。
答案 0 :(得分：0)
单击该项时，您只需将该配方发送到RecipePage：
var recipe = (Recipes)e.ClickedItem;
Frame.Navigate(typeof(RecipePage), recipe);
然后在RecipePage的OnNavigatedTo事件处理程序中获取此配方并将其设置为RecipePage的DataContext。
protected override void OnNavigatedTo(NavigationEventArgs e)
{
var recipe = e.Parameter as Recipes;
this.DataContext = recipe;
}
然后，您可以绑定到RecipePage上的任何Recipes属性。
