ViewModel不绑定

Question

我在stackoverflow上发现了很多关于数组和列表的内容，但没有绑定，但是我只有一个简单的视图模型，其中包含4个字符串，并且该帖子没有给我表格值：

ViewModel：

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

Answer 1

利用属性，而不要使用字段/变量，否则DataBinder根本不会绑定。 我还建议尽可能使用@Html.TextBoxFor(x => x.Email) 。

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