asp.net的MVC 4模型绑定的枚举 [英] asp.net mvc 4 model binding for enums

问题描述

的asp.net mvc的团队实现了一个默认的模式，枚举绑定？所以，它是开箱和没有必要创建自定义模型粘合剂枚举

Has the asp.net mvc team implemented a default model binding for enums? so that it is out of the box and there is no need of creating a custom model binder for enums.

更新：
可以说，我有一个将收到一个视图模型的动作。和一个JSON对象将被张贴到行动。

UPDATE:
Lets say I have an action that will be receiving a view model. and a json object will be posted to the action.

jsObj{id:2, name:'mike', personType: 1}

和视图模型：

class ViewModel
{
    public int id {get;set;}
    public string name {get;set;}
    public PersonType personType{get;set;}
}

public enum PersonType : int
{
   Good = 1,
   Bad = 2,
   Evil = 3
}

请问人类型绑定？

Will the person type be binded?

推荐答案

在那里甚至更早的版本。这html和性别=男形式值是否正确绑定到性别枚举属性。

It was there even with earlier versions. This html and Gender = Male form value is correctly binding to Gender enum property.

<select id="Gender" name="Gender">
     <option value="Male">Male</option>
     <option value="Female">Femal</option>
</select>

有关在服务器端，我觉得它最容易使用的选择列表在我的视图模型

For the server side I find it easiest to use select lists in my view model

public class User
{
    public UserType UserType { get; set; }

    public IEnumerable<SelectListItem> UserTypesSelectList { get; set; }

    public User()
    {
        UserTypesSelectList = Enum.GetNames(typeof(UserType)).Select(name => new SelectListItem()
        {
            Text = name,
            Value = MakeEnumMoreUserFriendly(name)
        });
    }
}

public enum UserType
{
    First,
    Second
}

和针对

@Html.DropDownListFor(model => model.UserType, Model.UserTypesSelectList)
