c# - 如何使用 Html.EditorFor 在 MVC3 中呈现单选按钮？

Question

这是我的模型:

[Required]
[Display(Name = "I'm a:")]
public bool Sex { get; set; }

还有我的编辑器模板:

<div>
    @Html.LabelFor(model => model.RegisterModel.Sex)
    @Html.EditorFor(model => model.RegisterModel.Sex)
</div>

但是这呈现如下:

<div>
    <label for="RegisterModel_Sex">Soy:</label>
    <input class="check-box" data-val="true" data-val-required="The Soy: field is required." id="RegisterModel_Sex" name="RegisterModel.Sex" type="checkbox" value="true" /><input name="RegisterModel.Sex" type="hidden" value="false" />
</div>

我如何为男性和女性呈现一些漂亮的单选按钮？我的模型必须具有什么数据类型？

编辑:

这是我新更新的代码:

//Model:
    [Required]
    [Display(Name = "Soy:")]
    public Gender Sex { get; set; }
}

public enum Gender
{
    Male = 1,
    Female = 2
}

//Viewmodel:

<fieldset>
    <legend>Informacion Personal</legend>
    <div>
        @Html.LabelFor(model => model.RegisterModel.Nombre)
        @Html.EditorFor(model => model.RegisterModel.Nombre)
    </div>

    <div>
        @Html.LabelFor(model => model.RegisterModel.Apellido)
        @Html.EditorFor(model => model.RegisterModel.Apellido)
    </div>

    <div>
        @Html.LabelFor(model => model.RegisterModel.Sex)
        @Html.EditorFor(model => model.RegisterModel.Sex)
    </div>

    <div>
        @Html.LabelFor(model => model.RegisterModel.Carnet)
        @Html.EditorFor(model => model.RegisterModel.Carnet)
    </div>    
</fieldset>


//EditorTemplate:

@model GoldRemate.WebUI.Models.Gender

@{
    ViewBag.Title = "Gender";
}

<input type="radio" name="Sex" value="@Model" />

当我运行它时，我得到这个错误:

The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'GoldRemate.WebUI.Models.Gender'.

这是什么原因造成的？我该如何在我的表单中显示我的枚举值？

像这样创建一个枚举:

 public enum Gender
 {
     Male = 1,
     Female = 2
 }

我会像这样稍微改变你的模型:

 public Gender Sex { get; set; }

然后在你看来你会这样做:

 Html.EditorFor(x => x.RegisterModel.Sex);

然后你会在这里有一个 EditorTemplate:

 ~/Views/Shared/EditorTemplates/Gender.cshtml

其中会有这样的内容:

@model EditorTemplate.Models.Gender // switch to your namespace

@Html.LabelFor(x => x, "Male")
@if(Model == EditorTemplate.Models.Gender.Male)
{
    @Html.RadioButtonFor(x => x, (int)EditorTemplate.Models.Gender.Male, new { @checked = "checked" });
}
else
{
    @Html.RadioButtonFor(x => x, (int)EditorTemplate.Models.Gender.Male);
}

@Html.LabelFor(x => x, "Female")
@if(Model == EditorTemplate.Models.Gender.Female)
{
    @Html.RadioButtonFor(x => x, (int)EditorTemplate.Models.Gender.Female, new { @checked = "checked" });
}
else
{
    @Html.RadioButtonFor(x => x, (int)EditorTemplate.Models.Gender.Female);
}

所以我在 Visual Studio 中对此进行了建模，并且按预期工作。试试吧。
