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();
    }

}

我不喜欢ActionSelectName的地方是IsValidName被控制器中的每个动作方法调用;我不知道为什么会这样。我喜欢一种解决方案，每个按钮都有一个不同的名称，基于它的功能，但我不喜欢这样的事实，你必须有许多参数在动作方法中的按钮在表单。我已经为所有按钮类型创建了一个枚举:

public enum ButtonType
{
    Submit,
    Cancel,
    Delete
}

而不是ActionSelectName，我使用ActionFilter:

public class MultipleButtonsEnumAttribute : ActionFilterAttribute
{
    public Type EnumType { get; set; }

    public MultipleButtonsEnumAttribute(Type enumType)
    {
        EnumType = enumType;
    }

    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        foreach (var key in filterContext.HttpContext.Request.Form.AllKeys)
        {
            if (Enum.IsDefined(EnumType, key))
            {
                var pDesc = filterContext.ActionDescriptor.GetParameters()
                    .FirstOrDefault(x => x.ParameterType == EnumType);
                filterContext.ActionParameters[pDesc.ParameterName] = Enum.Parse(EnumType, key);
                break;
            }
        }
    }
}

过滤器将在表单数据中找到按钮名称，如果按钮名称与枚举中定义的任何按钮类型匹配，它将在动作参数中找到ButtonType参数:

[MultipleButtonsEnumAttribute(typeof(ButtonType))]
public ActionResult Manage(ButtonType buttonPressed, ManageViewModel model)
{
    if (button == ButtonType.Cancel)
    {
        return RedirectToAction("Index", "Home");
    }
    //and so on
    return View(model)
}

然后在视图中，我可以使用:

<input type="submit" value="Button Cancel" name="@ButtonType.Cancel" />
<input type="submit" value="Button Submit" name="@ButtonType.Submit" />

Eilon建议你可以这样做:

If you have more than one button you can distinguish between them by giving each button a name: <input type="submit" name="SaveButton" value="Save data" /> <input type="submit" name="CancelButton" value="Cancel and go back to main page" /> In your controller action method you can add parameters named after the HTML input tag names: public ActionResult DoSomeStuff(string saveButton, string cancelButton, ... other parameters ...) { ... } If any value gets posted to one of those parameters, that means that button was the one that got clicked. The web browser will only post a value for the one button that got clicked. All other values will be null. if (saveButton != null) { /* do save logic */ } if (cancelButton != null) { /* do cancel logic */ }

我喜欢这个方法，因为它不依赖于提交按钮的值属性，这个属性比分配的名称更有可能改变，并且不需要启用javascript

你应该能够为按钮命名并赋予它们一个值;然后将此名称映射为操作的参数。或者，使用2个单独的动作链接或2个表单。

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;
    }
}

以下是最适合我的方法:

<input type="submit" value="Delete" name="onDelete" />
<input type="submit" value="Save" name="onSave" />


public ActionResult Practice(MyModel model, string onSave, string onDelete)
{
    if (onDelete != null)
    {
        // Delete the object
        ...
        return EmptyResult();
    }

    // Save the object
    ...
    return EmptyResult();
}
