枚举MVC3隐藏输入的值是枚举键值不值？ [英] MVC3 HiddenFor with Enum. Input's value is enum key not value?

问题描述

我有一个枚举：

public enum TaskType
{
    None = 100,
    Install = 101,
    Decommission = 102,
    Modify = 103,
    Rename = 104,
    Move = 105,
    Incident = 106,
    Other = 107
};

我想将我的视图中的当前值保存为我的模型的属性：

and I would like to represent its current value in my view by saving it as a property of my model:

public class ProvisioningListModel
{
    public TaskType TaskType { get; set; }

    public ProvisioningListModel(Task task)
    {
        TaskType = task.TaskType;
    }
}

我的视图有相应的：

<%=Html.HiddenFor(model => model.TaskType)%>

当生成相应的隐藏输入元素时，其值为安装而不是101.这对我来说似乎令人惊讶，因为枚举通常由他们的价值而不是他们的钥匙来处理。

When the appropriate hidden input element is generated, its value is "Install" and not "101." This seemed surprising to me because an enums are usually handled by their value not their key.

<input id="TaskType" name="TaskType" type="hidden" value="Install">

这是MVC中的常见问题吗？有一个简单的解决方案？

Is this a common issue in MVC? Is there an easy fix?

推荐答案

首先使你的枚举类型继承自int

first make your enum type to inherit from int

public enum TaskType :int
{
  ...

然后只需使用

<%=Html.HiddenFor(model => (int)model.TaskType)%>
