您可以像前面提到的那样检查动作中的名称，但是您可能会考虑这是否是好的设计。考虑动作的职责，不要将这种设计过多地与按钮名称等UI方面结合起来，这是一个好主意。所以考虑使用两种形式和两种动作:

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

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

此外，在“取消”的情况下，您通常只是不处理表单，而是转到一个新的URL。在这种情况下，你根本不需要提交表单，只需要一个链接:

<%=Html.ActionLink("Cancel", "List", "MyController") %>

Index.cshtml @using （Html.BeginForm（“Index”， “Home”， FormMethod.Post， new { id = “submitForm” }）） { 按钮类型=“提交” id=“btn批准” 名称=“命令” 值=“批准”>批准 按钮类型=“提交” id=“btn拒绝” 名称=“命令” 值=“拒绝”>拒绝 }

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Index(FormCollection frm, string Command)
    {
        if (Command == "Approve")
        {

        }
        else if (Command == "Reject")
        {

        }

        return View();
    }

}

给你的提交按钮一个名字，然后在你的控制器方法中检查提交的值:

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

发布到

public class MyController : Controller {
    public ActionResult MyAction(string submitButton) {
        switch(submitButton) {
            case "Send":
                // delegate sending to another controller action
                return(Send());
            case "Cancel":
                // call another action to perform the cancellation
                return(Cancel());
            default:
                // If they've submitted the form without a submitButton, 
                // just return the view again.
                return(View());
        }
    }

    private ActionResult Cancel() {
        // process the cancellation request here.
        return(View("Cancelled"));
    }

    private ActionResult Send() {
        // perform the actual send operation here.
        return(View("SendConfirmed"));
    }

}

编辑:

要将此方法扩展到本地化站点，请将您的消息隔离在其他地方(例如将资源文件编译为强类型资源类)

然后修改代码，使其像这样工作:

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

你的控制器应该是这样的:

// Note that the localized resources aren't constants, so 
// we can't use a switch statement.

if (submitButton == Resources.Messages.Send) { 
    // delegate sending to another controller action
    return(Send());

} else if (submitButton == Resources.Messages.Cancel) {
     // call another action to perform the cancellation
     return(Cancel());
}

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"…

这个脚本允许指定一个data-form-action属性，它将在所有浏览器中作为HTML5 formaction属性(以一种不引人注目的方式):

$(document).on('click', '[type="submit"][data-form-action]', function(event) {
    var $this = $(this),
    var formAction = $this.attr('data-form-action'),
    $form = $($this.closest('form'));
    $form.attr('action', formAction);             
});

包含按钮的表单将被发送到data-form-action属性中指定的URL:

<button type="submit" data-form-action="different/url">Submit</button>   

这需要jQuery 1.7。对于以前的版本，您应该使用live()而不是on()。

我的JQuery方法使用扩展方法:

public static MvcHtmlString SubmitButtonFor<TController>(this HtmlHelper helper, Expression<Action<TController>> action, string value) where TController : Controller
{
    RouteValueDictionary routingValues = Microsoft.Web.Mvc.Internal.ExpressionHelper.GetRouteValuesFromExpression(action);

    var onclick = string.Format("$('form').first().attr('action', '/{0}')", string.Join("/", routingValues.Values.ToArray().Where(x => x != null).Select(x => x.ToString()).ToArray()));
    var html = "<input type=\"submit\" value=\"" + value + "\" onclick=\"" + onclick + "\" />";

    return MvcHtmlString.Create(html);
}

你可以这样使用它:

@(Html.SubmitButtonFor<FooController>(c => c.Save(null), "Save"))

它是这样渲染的:

<input type="submit" value="Save" onclick="$('form').first().attr('action', '/Foo/Save')" >
