我想为这些数据实体创建CRUD操作：

public class Userviewmodel 
{  
   protected virtual Id {get; set;} 
   public virtual string Login { get; set; }
   public virtual string Password { get; set; }
   public virtual ZipCodeviewmodel ZipCode { get; set; }
}

邮政编码实体：

public class ZipCodeviewmodel
{        
   public virtual string City { get; set; }

   public virtual string State { get; set; }           

   public virtual string Zip { get; set; }
}

我也有部分视图ZipCode使用Userviewmodel.ZipCode：

@model ZipCodeviewmodel    

    @Html.TextBoxFor(x => x.Zip,new { id = "ZipCode",name = "ZipCode.Zip",maxlength = "5" })

我将在另一个页面(例如用户)中使用ZipCodePartialView.

@model Userviewmodel
.....
@{Html.RenderPartial("Zipcode",Model.ZipCode);}

当MVC保存用户ZipCode字段Zip为空时.

那么问题是我如何为patrial View添加模型前缀？
