[英]Model binder woes
why do I always have so much trouble with the model binder?? 为什么我总是对模型活页夹有太多麻烦? I have the following controller: 我有以下控制器:
namespace X.Web.Controllers
{
public class ExpertsVM
{
public string GivenName;
public string Surname;
}
public class AuthController : Controller
{
[HttpPost]
public ActionResult RegisterExpert(ExpertsVM v)
{
and my view looks like this: 我的看法如下所示:
@using X.Web.Controllers
@model ExpertsVM
@using (Html.BeginForm("RegisterExpert", "Auth"))
{
@Html.EditorFor(x => x.GivenName)
@Html.EditorFor(x => x.Surname)
so the form gets rendered like this: 因此,表单的呈现方式如下:
<form action="/Auth/RegisterExpert" method="post">
<input class="text-box single-line" id="GivenName" name="GivenName" type="text" value="" />
<input class="text-box single-line" id="Surname" name="Surname" type="text" value="" />
but when the action gets invoked, v
contains all nulls. 但是当操作被调用时, v
包含所有空值。 if I declare the action like this: 如果我这样声明动作:
[HttpPost]
public ActionResult RegisterExpert(FormCollection f)
{
I see all the values... so what am I doing wrong here? 我看到了所有的价值...所以我在这里做错了什么?
I'm not 100% sure but I would use property instead of public field. 我不确定100%,但是我会使用属性而不是公共领域。
try 尝试
public class ExpertsVM
{
public string GivenName {get;set;}
public string Surname {get;set;}
}
The model binder looks for public properties on the model. 模型绑定程序在模型上查找公共属性。 VdesmedT's answer is right, but I am adding this to add emphasis to the point (he wasn't 100% sure, I am). VdesmedT的答案是正确的,但是我添加这个来强调这一点(我不是100%肯定的)。
You could also spare yourself one of the using statments by doing: 您还可以通过执行以下操作来避免使用其中之一:
@model X.Web.Controllers.ExpertsVM
I have upvoted VdesmedT's answser. 我对VdesmedT的答案表示反对。 You should mark that as the answer. 您应该将其标记为答案。
