asp.net mvc int[] 和 string[] 自定义数组绑定

新建类，int[]数组模型绑定

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;



namespace Koukou.Admin.ModelBinder

{

    public class IntArrayModelBinder : DefaultModelBinder

    {

        public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)

        {

            var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

            if (value == null || string.IsNullOrEmpty(value.AttemptedValue))

            {

                return null;

            }



            return value

                .AttemptedValue

                .Split(',')

                .Select(int.Parse)

                .ToArray();

        }

    }

}

 

string[] 数组模型绑定

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;



namespace Koukou.Admin.ModelBinder

{

    public class StringArrayModelBinder : DefaultModelBinder

    {

        public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)

        {

            var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

            if (value == null || string.IsNullOrEmpty(value.AttemptedValue))

            {

                return null;

            }



            return value

                .AttemptedValue

                .Split(new string[] { ",", Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);

            // 逗号“，” 和 换行符 作为分隔

        }

    }

}

 

在global.asax的Application_Start注册

protected void Application_Start()

        {

            AreaRegistration.RegisterAllAreas();



            RegisterGlobalFilters(GlobalFilters.Filters);

            RegisterRoutes(RouteTable.Routes);



//自定义model绑定

            ModelBinders.Binders.Add(typeof(int[]), new ModelBinder.IntArrayModelBinder());

            ModelBinders.Binders.Add(typeof(string[]), new ModelBinder.StringArrayModelBinder());

        }
