使用IModelBinder自定义模型绑定

本文关键字：绑定 模型 自定义 IModelBinder 使用 | 更新日期: 2023-09-27 18:26:07

我正在尝试编写自定义模型绑定器，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）'

使用IModelBinder自定义模型绑定

您正在使用的IModelBinder来自System.Web.ModelBinding命名空间。此接口的BindModel方法返回布尔类型的值。

bool BindModel(
    ModelBindingExecutionContext modelBindingExecutionContext,
    ModelBindingContext bindingContext
)

如果要使用返回对象的BindModel方法，则需要从System.Web.Mvc命名空间实现接口。

Object BindModel(
    ControllerContext controllerContext,
    ModelBindingContext bindingContext
)

您可以在实现此IModelBinder接口时通过提供完整的命名空间来检查它。像

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;
}
}
