asp.net-mvc-4 - 多选枚举

Question

我正在开发一种工具，以便我可以在游戏中保持井井有条。

这是我的课:

//The item
public class Item
{
    public int Id { get; set; }
    public string Name { get; set; }
    public decimal Value { get; set; }
    public ItemLabel Label { get; set; }
    public ItemType Type { get; set; }
    public ItemTradeType TradeType { get; set; }
    public Trade Trade { get; set; }
}

Label/Type/TradeType/Trade 是枚举。

查看:

@model EveMonitorV2.Models.Item

@{
    ViewBag.Title = "AddItem";
}

<h2>AddItem</h2>

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>Item</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.Name)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Name)
            @Html.ValidationMessageFor(model => model.Name)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Value)
        </div>

//What should be done here?

        <div class="editor-field">
            @Html.EditorFor(model => model.Value)
            @Html.ValidationMessageFor(model => model.Value)
        </div>


        <div class="editor-label">
            @Html.LabelFor(model => model.Trade)
        </div>
        <div class="editor-field">
            @Html.CheckBoxFor()
            @Html.ValidationMessageFor(model => model.Trade)
        </div>


        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

枚举有完整的可能性列表，我想创建一个项目创建 View

我遇到的问题:

我希望能够从枚举中选择更多选项。 (Like this) 其中类别是我的枚举。

这在 asp.net mvc 4 中可能吗？

(小注:我还是一名学生，但这不是学校项目)

Answer 1

创建View\Shared\EditorTemplates\Options.cshtml

@using System.ComponentModel.DataAnnotations
@using System.Reflection
@model Enum
@{
    var name = ViewData.TemplateInfo.HtmlFieldPrefix;
    var type = Model.GetType();
}

@foreach (Enum e in Enum.GetValues(type))
{
    var display = type.GetField(e.ToString()).GetCustomAttribute<DisplayAttribute>();
    if (display != null && (display.GetAutoGenerateField() ?? true))
    {
    <label class="checkbox" title="@display.GetDescription()">
        <input type="checkbox" name="@name" value="@e.ToString()" checked="@Model.HasFlag(e)" />
        @display.Name
    </label>
    }
}

您的枚举可能如下描述:

[Flags]
public enum MyOptions
{
    [Display(AutoGenerateField = false)]
    None = 0,
    [Display(Name = "Option 1 name")]
    Opt1 = 1 << 1,
    [Display(Name = "Option 2 name")]
    Opt2 = 1 << 2,
    [Display(Name = "Option 3 name")]
    Opt3 = 1 << 3,
}

比，使用:

    <div class="editor-field">
        @Html.LabelFor(m => m.Trade)
        @Html.EditorFor(m => m.Trade, "Options")
    </div>
