我的解决方案是使用2个asp面板:

< asp:面板ID = " . . "DefaultButton = " ID_OF_SHIPPING_SUBMIT_BUTTON "…> < / asp:面板>

你可以这样写:

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<input type="submit" name="button" value="Send" />
<input type="submit" name="button" value="Cancel" />
<% Html.EndForm(); %>

然后在页面中检查name == "Send"或者name == "Cancel"…

下面是我写的一个扩展方法来处理多个图像和/或文本按钮。

下面是一个图片按钮的HTML:

<input id="btnJoin" name="Join" src="/content/images/buttons/btnJoin.png" 
       type="image">

或者对于文本提交按钮:

<input type="submit" class="ui-button green" name="Submit_Join" value="Add to cart"  />
<input type="submit" class="ui-button red" name="Submit_Skip" value="Not today"  />

下面是使用form.GetSubmitButtonName()从控制器调用的扩展方法。对于图像按钮，它查找带有.x的表单参数(表示单击了图像按钮)并提取名称。对于常规输入按钮，它查找以Submit_开头的名称并从中提取命令。因为我抽象了确定“命令”的逻辑，所以你可以在客户端上切换图像+文本按钮，而无需更改服务器端代码。

public static class FormCollectionExtensions
{
    public static string GetSubmitButtonName(this FormCollection formCollection)
    {
        return GetSubmitButtonName(formCollection, true);
    }

    public static string GetSubmitButtonName(this FormCollection formCollection, bool throwOnError)
    {
        var imageButton = formCollection.Keys.OfType<string>().Where(x => x.EndsWith(".x")).SingleOrDefault();
        var textButton = formCollection.Keys.OfType<string>().Where(x => x.StartsWith("Submit_")).SingleOrDefault();

        if (textButton != null)
        {
            return textButton.Substring("Submit_".Length);
        }

        // we got something like AddToCart.x
        if (imageButton != null)
        {
            return imageButton.Substring(0, imageButton.Length - 2);
        }

        if (throwOnError)
        {
            throw new ApplicationException("No button found");
        }
        else
        {
            return null;
        }
    }
}

注意:对于文本按钮，必须在名称前加上Submit_。我更喜欢这种方式，因为这意味着您可以更改文本(显示)值，而不必更改代码。与SELECT元素不同，INPUT按钮只有一个“value”，没有单独的“text”属性。我的按钮在不同的上下文中表示不同的内容-但映射到相同的“命令”。我更喜欢以这种方式提取名称，而不是必须为==“Add to cart”编码。

我已经为HtmlHelper创建了一个ActionButton方法。它将在OnClick事件中生成带有javascript的普通输入按钮，将表单提交给指定的控制器/动作。

像这样使用辅助器

@Html.ActionButton("MyControllerName", "MyActionName", "button text")

这将生成以下HTML

<input type="button" value="button text" onclick="this.form.action = '/MyWebsiteFolder/MyControllerName/MyActionName'; this.form.submit();">

下面是扩展方法代码:

VB。网

<System.Runtime.CompilerServices.Extension()>
Function ActionButton(pHtml As HtmlHelper, pAction As String, pController As String, pRouteValues As Object, pBtnValue As String, pBtnName As String, pBtnID As String) As MvcHtmlString
    Dim urlHelperForActionLink As UrlHelper
    Dim btnTagBuilder As TagBuilder

    Dim actionLink As String
    Dim onClickEventJavascript As String

    urlHelperForActionLink = New UrlHelper(pHtml.ViewContext.RequestContext)
    If pController <> "" Then
        actionLink = urlHelperForActionLink.Action(pAction, pController, pRouteValues)
    Else
        actionLink = urlHelperForActionLink.Action(pAction, pRouteValues)
    End If
    onClickEventJavascript = "this.form.action = '" & actionLink & "'; this.form.submit();"

    btnTagBuilder = New TagBuilder("input")
    btnTagBuilder.MergeAttribute("type", "button")

    btnTagBuilder.MergeAttribute("onClick", onClickEventJavascript)

    If pBtnValue <> "" Then btnTagBuilder.MergeAttribute("value", pBtnValue)
    If pBtnName <> "" Then btnTagBuilder.MergeAttribute("name", pBtnName)
    If pBtnID <> "" Then btnTagBuilder.MergeAttribute("id", pBtnID)

    Return MvcHtmlString.Create(btnTagBuilder.ToString(TagRenderMode.Normal))
End Function

c# (c#代码只是从VB DLL中反编译的，所以它可以得到一些美化…但是时间太短了:-)

public static MvcHtmlString ActionButton(this HtmlHelper pHtml, string pAction, string pController, object pRouteValues, string pBtnValue, string pBtnName, string pBtnID)
{
    UrlHelper urlHelperForActionLink = new UrlHelper(pHtml.ViewContext.RequestContext);
    bool flag = Operators.CompareString(pController, "", true) != 0;
    string actionLink;
    if (flag)
    {
        actionLink = urlHelperForActionLink.Action(pAction, pController, System.Runtime.CompilerServices.RuntimeHelpers.GetObjectValue(pRouteValues));
    }
    else
    {
        actionLink = urlHelperForActionLink.Action(pAction, System.Runtime.CompilerServices.RuntimeHelpers.GetObjectValue(pRouteValues));
    }
    string onClickEventJavascript = "this.form.action = '" + actionLink + "'; this.form.submit();";
    TagBuilder btnTagBuilder = new TagBuilder("input");
    btnTagBuilder.MergeAttribute("type", "button");
    btnTagBuilder.MergeAttribute("onClick", onClickEventJavascript);
    flag = (Operators.CompareString(pBtnValue, "", true) != 0);
    if (flag)
    {
        btnTagBuilder.MergeAttribute("value", pBtnValue);
    }
    flag = (Operators.CompareString(pBtnName, "", true) != 0);
    if (flag)
    {
        btnTagBuilder.MergeAttribute("name", pBtnName);
    }
    flag = (Operators.CompareString(pBtnID, "", true) != 0);
    if (flag)
    {
        btnTagBuilder.MergeAttribute("id", pBtnID);
    }
    return MvcHtmlString.Create(btnTagBuilder.ToString(TagRenderMode.Normal));
}

这些方法具有各种参数，但是为了便于使用，您可以创建一些重载，只使用所需的参数。

这是我发现的最好的方法:

http://iwayneo.blogspot.co.uk/2013/10/aspnet-mvc-action-selector-with-list.html

代码如下:

    /// <summary>
    /// ActionMethodSelector to enable submit buttons to execute specific action methods.
    /// </summary>
    public class AcceptParameterAttribute : ActionMethodSelectorAttribute
   {
        /// <summary>
        /// Gets or sets the value to use to inject the index into
        /// </summary>
       public string TargetArgument { get; set; }

       /// <summary>
       /// Gets or sets the value to use in submit button to identify which method to select. This must be unique in each controller.
       /// </summary>
       public string Action { get; set; }

       /// <summary>
       /// Gets or sets the regular expression to match the action.
       /// </summary>
       public string ActionRegex { get; set; }

       /// <summary>
       /// Determines whether the action method selection is valid for the specified controller context.
       /// </summary>
       /// <param name="controllerContext">The controller context.</param>
       /// <param name="methodInfo">Information about the action method.</param>
       /// <returns>true if the action method selection is valid for the specified controller context; otherwise, false.</returns>
       public override bool IsValidForRequest(ControllerContext controllerContext, MethodInfo methodInfo)
       {

           if (controllerContext == null)
           {
               throw new ArgumentNullException("controllerContext");
           }

           Func<NameValueCollection> formGetter;
           Func<NameValueCollection> queryStringGetter;

           ValidationUtility.GetUnvalidatedCollections(HttpContext.Current, out formGetter, out queryStringGetter);

           var form = formGetter();
           var queryString = queryStringGetter();

           var req = form.AllKeys.Any() ? form : queryString;

           if (!string.IsNullOrEmpty(this.ActionRegex))
           {
               foreach (var key in req.AllKeys.Where(k => k.StartsWith(Action, true, System.Threading.Thread.CurrentThread.CurrentCulture)))
               {
                   if (key.Contains(":"))
                   {
                       if (key.Split(':').Count() == this.ActionRegex.Split(':').Count())
                       {
                           bool match = false;
                           for (int i = 0; i < key.Split(':').Count(); i++)
                           {
                               if (Regex.IsMatch(key.Split(':')[0], this.ActionRegex.Split(':')[0]))
                               {
                                   match = true;
                               }
                               else
                               {
                                   match = false;
                                   break;
                               }
                           }

                           if (match)
                           {
                               return !string.IsNullOrEmpty(req[key]);
                           }
                       }
                   }
                   else
                   {
                       if (Regex.IsMatch(key, this.Action + this.ActionRegex))
                       {
                           return !string.IsNullOrEmpty(req[key]);
                       }
                   }

               }
               return false;
           }
           else
           {
               return req.AllKeys.Contains(this.Action);
           }
       }
   }

享受一个没有代码气味的多提交按钮的未来。

谢谢你！

我来派对已经很晚了，但现在开始… 我的实现借用了@mkozicki，但需要更少的硬编码字符串来出错。需要4.5+框架。实际上，控制器方法名应该是路由的关键。

标记。按钮名称必须以“action:[controllerMethodName]”为键

(注意使用c# 6的API名称，提供了对希望调用的控制器方法名称的特定类型引用。

<form>
    ... form fields ....
    <button name="action:@nameof(MyApp.Controllers.MyController.FundDeathStar)" type="submit" formmethod="post">Fund Death Star</button>
    <button name="action:@nameof(MyApp.Controllers.MyController.HireBoba)" type="submit" formmethod="post">Hire Boba Fett</button>
</form>

控制器:

namespace MyApp.Controllers
{
    class MyController
    {    
        [SubmitActionToThisMethod]
        public async Task<ActionResult> FundDeathStar(ImperialModel model)
        {
            await TrainStormTroopers();
            return View();
        }

        [SubmitActionToThisMethod]
        public async Task<ActionResult> HireBoba(ImperialModel model)
        {
            await RepairSlave1();
            return View();
        }
    }
}

属性的魔法。注意使用CallerMemberName功能。

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public class SubmitActionToThisMethodAttribute : ActionNameSelectorAttribute
{        
    public SubmitActionToThisMethodAttribute([CallerMemberName]string ControllerMethodName = "")
    {
        controllerMethod = ControllerMethodName;
        actionFormat = string.Concat(actionConstant, ":", controllerMethod);
    }
    const string actionConstant = "action";
    readonly string actionFormat;
    readonly string controllerMethod;

    public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
    {
        var isValidName = false;
        var value = controllerContext.Controller.ValueProvider.GetValue(actionFormat);

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