Web Api不会序列化我的对象图

Question

我有两个简单的实体：

public class Ingredient : IEntity
{
    public Ingredient()
    {
        Drinks = new List<Drink>();
    }

    public int Id { get; set; }
    public string Name { get; set; }
    public virtual ICollection<Drink> Drinks { get; set; }
}

public class Drink : IEntity
{
    public Drink()
    {
        Ingridients = new List<Ingredient>();
    }

    public int Id { get; set; }
    public string Name { get; set; }
    public virtual ICollection<Ingredient> Ingridients { get; set; }
    public string Approach { get; set; }
}

我收到以下错误：

Object graph for type 'Gudo.Core.Model.Ingredient' contains cycles and cannot be serialized if reference tracking is disabled.

我尝试使用JsonIgnore集合上的Drinks属性，我尝试过使用：

JsonSerializerSettings jsSettings = new JsonSerializerSettings();
        jsSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;

在我的global.asax

中

没有任何作用..

请帮忙。

您确定在JSON格式化程序的序列化程序设置上设置了此项吗？这一行应该为你做到：

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
