如何处理ASP.NET MVC Framework中的多个提交按钮？

在很大程度上基于MaartenBalliauw的帖子和评论，这是一个针对多个提交按钮问题的基于属性的，几乎干净的解决方案。

[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;    }}

razor:

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

and controller:

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