寧靜的C＃頁面無法顯示正確

Question

我有一個控制器：

public IEnumerable<Food> Get() 
{ 
    FoodDiaryContext cs = new FoodDiaryContext(); 
    var foodquery = cs.Foods.OrderByDescending(c => c.Description).ToList(); 

    return foodquery; 
} 

它應該顯示：

{ 
    id:1 
    description:food 
    measure:[] 
} 

但我得到一個錯誤：

Type 'System.Data.Entity.DynamicProxies.Food_219DB877F13A4776536ADFD2AC86DB1FDBF0E8887DB7E9D658EFE7D9462C3BD5' with data contract name 'Food_219DB877F13A4776536ADFD2AC86DB1FDBF0E8887DB7E9D658EFE7D9462C3BD5: http://schemas.datacontract.org/2004/07/System.Data.Entity.DynamicProxies ' is not expected. Consider using a DataContractResolver if you are using DataContractSerializer or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to the serializer.

public class Food 
{ 
    public Food() 
    { 
     Measures = new List<Measure>(); 
    } 

    public int Id { get; set; } 
    public string Description { get; set; } 
    public virtual ICollection<Measure> Measures { get; set; } 
} 

public class Measure 
{ 
    public int Id { get; set; } 
    public string Description { get; set; } 
    public double Calories { get; set; } 
    public double Fats { get; set; } 
    public double Protein { get; set; } 
    public double Carbohydrates { get; set; } 
    public virtual Food Food { get; set; } 
} 

燦任何人都請告訴我我做錯了什麼？

謝謝

感謝您的幫助。 我確實希望你建議，它的工作原理。

public class FoodDiaryContext:DbContext 
    { 
     public FoodDiaryContext() 
     { 
      this.Configuration.ProxyCreationEnabled = false; 
     } 

     public DbSet<Food> Foods { get; set; } 
     public DbSet<Measure> Measures { get; set; } 
    }
