把视图省、市、街道表单数据，封装成一个类，作为action参数。如下：
action方法参数类型：
namespace MvcApplication1.Models
{
public class
Customer
{
public string Address { get; set; }
}
}
在自定义ModelBinder中，接收视图表单数据，封装成Customer类。
using System.Web;
using System.Web.Mvc;
using MvcApplication1.Models;namespace MvcApplication1.Extension
{
public class CustomerBinder : DefaultModelBinder
{
public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
if (bindingContext.ModelType == typeof (Customer))
{
HttpRequestBase request = controllerContext.HttpContext.Request;
string province = request.Form.Get("Province");
string city = request.Form.Get("City");
string street = request.Form.Get("street");return new Customer() {Address = province+city+street};
}
else
{
return base.BindModel(controllerContext, bindingContext);
}}
}
}
全局注册：
ModelBinders.Binders.Add(typeof(Customer), new CustomerBinder());
HomeController:
using System.Web.Mvc;
using MvcApplication1.Extension;
using MvcApplication1.Models;namespace MvcApplication1.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}[HttpPost]
public ActionResult Index([ModelBinder(typeof(CustomerBinder))]Customer customer)
{
if (ModelState.IsValid)
{
return Content(customer.Address);
}
return View();
}
}
}
Home/Index.cshtml:
@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Index</h2>
@using (Html.BeginForm())
{
<table>
<tr>
<td>省</td>
<td><input type="text" id="Province" name="Province"/></td>
</tr>
<tr>
<td>市</td>
<td><input type="text" id="City" name="City"/></td>
</tr>
<tr>
<td>街道</td>
<td><input type="text" id="Street" name="Street"/></td>
</tr>
<tr>
<td colspan="2"><input type="submit" value="提交"/></td>
</tr>
</table>
}
提交后结果：
MVC扩展ModelBinder,通过继承DefaultModelBinder把表单数据封装成类作为action参数,布布扣,bubuko.com
