【MVC5】画面多按钮提交

画面上有个多个按钮时，如何绑定到各自的Action上?

1.追加如下MultipleButtonAttribute类

using System;
using System.Reflection;
using System.Web.Mvc;

namespace DailyReportSystem.Attribute
{
    [AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
    public class MultipleButtonAttribute : ActionNameSelectorAttribute
    {
        public string Name { get; set; }
        public string Argument { get; set; }

        public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
        {
            var isValidName = false;
            var keyValue = string.Format("{0}:{1}", Name, Argument);
            var value = controllerContext.Controller.ValueProvider.GetValue(keyValue);

            if (value != null)
            {
                controllerContext.Controller.ControllerContext.RouteData.Values[Name] = Argument;
                isValidName = true;
            }

            return isValidName;
        }
    }
}

2.Razor（给按钮追加name属性，值的格式为【{Name}:{Argument}】）

<form action="" method="post">
 <input type="submit" value="Save" name="action:Save" />
 <input type="submit" value="Cancel" name="action:Cancel" />
</form>

3.Controller（参数Name和Argument对应按钮的name属性值）

[HttpPost]
[MultipleButton(Name = "action", Argument = "Save")]
public ActionResult Save(MessageModel mm) { ... }

[HttpPost]
[MultipleButton(Name = "action", Argument = "Cancel")]
public ActionResult Cancel(MessageModel mm) { ... }
