JsonConvert.SerializeObject序列化对象，对象里面含有虚方法的时候，怎么过滤？

[fsb1582813]

JsonConvert.SerializeObject序列化时候，报错，出现了死循环，
我的方法：
JsonSerializerSettings MyJsonSerializerSettings = new JsonSerializerSettings();
MyJsonSerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
IsoDateTimeConverter dateTimeConverter = new IsoDateTimeConverter();
dateTimeConverter.DateTimeFormat = "yyyy-MM-dd HH:mm:ss";
MyJsonSerializerSettings.Converters.Add(dateTimeConverter);
return Content(JsonConvert.SerializeObject(date, Formatting.Indented, MyJsonSerializerSettings));

我的实体类：
public partial class Customers
{
public Customers()
{
this.Shop_Coupons = new HashSet<Shop_Coupons>();
this.PointValueRecords = new HashSet<PointValueRecords>();
this.shop_MakeComplaints = new HashSet<shop_MakeComplaints>();
this.Shop_SaleOrders = new HashSet<Shop_SaleOrders>();
this.Shop_ShoppingCarts = new HashSet<Shop_ShoppingCarts>();
}

public int Id { get; set; }
public string UserName { get; set; }
public string NickName { get; set; }
public string Email { get; set; }
public string Tel { get; set; }
public string PwdLogin { get; set; }
public string PwdPay { get; set; }
public Nullable<int> SecurityLevel { get; set; }
public System.DateTime RegisterDate { get; set; }

public string Profession { get; set; }

public string Birthday { get; set; }
public string Adress { get; set; }
public Nullable<int> ProvinceID { get; set; }
public Nullable<int> CityID { get; set; }
public Nullable<int> DistrictId { get; set; }
public string HeadImgUrl { get; set; }

public virtual CustomerEpds CustomerEpds { get; set; }
public virtual ICollection<Shop_Coupons> Shop_Coupons { get; set; }
public virtual ICollection<PointValueRecords> PointValueRecords { get; set; }
public virtual ICollection<shop_MakeComplaints> shop_MakeComplaints { get; set; }
public virtual ICollection<Shop_SaleOrders> Shop_SaleOrders { get; set; }
public virtual ICollection<Shop_ShoppingCarts> Shop_ShoppingCarts { get; set; }
}

终于解决了，this.Configuration.LazyLoadingEnabled = true; this.Configuration.ProxyCreationEnabled = false;//加了这一句

对不需要实例化的属性添加[NonSerialized]属性
