为什么将此ASP.net MVC发布到控制器后会导致模型为空？

Question

In the following code, the Product object is always getting set to null - but if I debug, I can see that the values are being posted correctly. What's going on?

Model:

public class Product {
    public string Name { get; set; }
    public string Model { get; set; }
}

Controller:

[HttpPost]
public ActionResult NewProduct(Product model) {
    if (model == null) { throw new NullReferenceException("model is null D:"); }
    // Do other things
    return View();
}

View:

@using (Html.BeginForm("NewProduct", "Home")) {

    <table>
        <tr>
            <td>Name</td>
            <td>@Html.EditorFor(model => model.Name)</td>
        </tr>
        <tr>
            <td>Model</td>
            <td>@Html.EditorFor(model => model.Model)</td>
        </tr>
    </table>
    <input type="submit" value="Add" />
}

Answer 1

Rename the parameter on the controller action

The parameter of the controller method cannot be named the same as any of the properties of the model or the binder won't bind properly

[HttpPost]
public ActionResult NewProduct(Product newProduct) {
    if (newProduct == null) { throw new NullReferenceException("model is null D:"); }
    // Do other things
    return View();
}

Note: this comparison is case insensitive - here the parameter was model and the object had a Model property but it still bugged out.
