ViewModel没有绑定

Question

我在stackoverflow上发现了一堆关于数组和列表没有绑定但是我只有一个简单的视图模型有4个字符串而且帖子没有给我表单值:

视图模型:

public class ReferralNetworkSearchCriteria
{
    public string Email = "";
    public string FirstName = "";
    public string LastName = "";
    public string TaxSSN = "";
}

ReferralNetworkController:

public ActionResult Search()
{
    ReferralNetworkSearchCriteria criteria = new ReferralNetworkSearchCriteria();
    return View(criteria);
}

[HttpPost]
public ActionResult Search(ReferralNetworkSearchCriteria criteria)

{
    return View(criteria);
}

视图:

@using OurCompany.ViewModels
@model ReferralNetworkSearchCriteria

@{
    ViewBag.Title = "Search Referral Network";
}

<h2>Search Referral Network</h2>

@using(Html.BeginForm("Search","ReferralNetwork",FormMethod.Post))
{
<fieldset>
    <div class="row">
        <div class="large-4 column">
            <label>Email</label>            
            @Html.TextBox("Email")
        </div>
        <div class="large-4 column">
            <label>
                First Name</label>
            @Html.TextBox("FirstName")
        </div>
        <div class="large-4 column">
            <label>
                Last Name</label>
            @Html.TextBox("LastName")
        </div>
    </div>
    <div class="row">
        <div class="large-4 column">
            <label>SSN/Tax ID</label>
            @Html.TextBox("TaxSSN")
        </div>
    </div>
    <div class="row">
        <div class="large-2 column">
            @Html.ActionLink("Back", "Index", "ReferralNetwork", null, new { @class = "button", @style="width:100%"})
        </div>
        <div class="large-2 column">        
            <button style="width:100%">Search</button>
        </div>
    </div>
</fieldset>    
}

*编辑:我也尝试使用@Html.TextBoxFor(x => x.Email)所有文本输入,但帖子上仍然没有值.谢谢

利用属性,而不是字段/变量,否则DataBinder根本就不会绑定.我也建议@Html.TextBoxFor(x => x.Email)尽可能使用.

public class ReferralNetworkSearchCriteria
{
    public string Email { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string TaxSSN { get; set; }
}
