C# 使用IModelBinder自定义模型绑定

我试图编写自定义模型活页夹，但它给出了一个错误。有人能告诉我哪里做错了吗

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MvcApplication1.Models
{
public class CustomModelBinder : IModelBinder
{
    public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        Ownership own = new Ownership();
        own.name = controllerContext.HttpContext.Request.Form["fName"];
        own.email = controllerContext.HttpContext.Request.Form["fEmail"];
        own.PhoneNo = controllerContext.HttpContext.Request.Form["fPhoneNo"];
        own.country = controllerContext.HttpContext.Request.Form["Country"];
        own.address = controllerContext.HttpContext.Request.Form["Adres"];
        own.office = controllerContext.HttpContext.Request.Form["Off"];
        own.officeEmail = controllerContext.HttpContext.Request.Form["OffEmail"];
        own.officeNo = controllerContext.HttpContext.Request.Form["OffNo"];
        own.OwnershipType = controllerContext.HttpContext.Request.Form["OwnershipType"];
        own.ProductId = controllerContext.HttpContext.Request.Form["ProductId"];

        return own;
    }
}

}

错误

“'CustomModelBinder'未实现接口成员 'System.Web.Mvc.IModelBinder.BindModel（System.Web.Mvc.ControllerContext， System.Web.Mvc.ModelBindingContext）'

---

您使用的IModelBinder来自System.Web.ModelBinding命名空间。此接口的BindModel方法返回bool类型的值

bool BindModel(
    ModelBindingExecutionContext modelBindingExecutionContext,
    ModelBindingContext bindingContext
)

若您想使用返回对象的BindModel方法，那个么您需要实现来自System.Web.Mvc命名空间的接口

Object BindModel(
    ControllerContext controllerContext,
    ModelBindingContext bindingContext
)

在实现这个IModelBinder接口时，您可以通过提供完整的名称空间来检查它

public class CustomModelBinder : System.Web.Mvc.IModelBinder
{
   public object BindModel(ControllerContext controllerContext, 
               ModelBindingContext bindingContext)
 {
    Ownership own = new Ownership();
    own.name = controllerContext.HttpContext.Request.Form["fName"];
    own.email = controllerContext.HttpContext.Request.Form["fEmail"];
    own.PhoneNo = controllerContext.HttpContext.Request.Form["fPhoneNo"];
    own.country = controllerContext.HttpContext.Request.Form["Country"];
    own.address = controllerContext.HttpContext.Request.Form["Adres"];
    own.office = controllerContext.HttpContext.Request.Form["Off"];
    own.officeEmail = controllerContext.HttpContext.Request.Form["OffEmail"];
    own.officeNo = controllerContext.HttpContext.Request.Form["OffNo"];
    own.OwnershipType = controllerContext.HttpContext.Request.Form["OwnershipType"];
    own.ProductId = controllerContext.HttpContext.Request.Form["ProductId"];

    return own;
}
}

您是否已将其添加到

ModelBinders.Binders.Add（typeof（Ownership），new CustomModelBinder（））；

中的global.asax？您还需要

public void MyAction（[ModelBinder（typeof（CustomModelBinder））]所有权所有者）

在控制器中，您可以提供包含名称空间的整个文件吗？是的，我在global.asax文件中添加了它，并且与您在控制器中编写的操作相同。谢谢您的评论@artm@danyloid：如何与您共享文件？Thanks@Asadkamal您需要重建应用程序。如果没有帮助，请清理

bin

obj

和

临时ASP.NET文件

（最后一个文件的位置取决于您使用的web服务器的类型）我尝试过，但它不起作用，在编译时会出现相同的错误
