将此添加到GetDefaults()方法中的基本控制器中

    protected override void OnActionExecuting(ActionExecutingContext filterContext)
    {
         GetDefaults();
         base.OnActionExecuting(filterContext);
    }

    private void GetDefaults()
    {
    var actionName = filterContext.ActionDescriptor.ActionName;
    var controllerName = filterContext.ActionDescriptor.ControllerDescriptor.ControllerName;
    }

实现你的控制器到Basecontroller

添加一个局部视图_Breadcrumb。CSHTML并将其添加到所有必需的页面中 @Html.Partial(“_Breadcrumb”)

_Breadcrumb.cshtml

<span>
    <a href="../@ViewData["controllerName"]">
        @ViewData["controllerName"]
    </a> > @ViewData["actionName"]
</span>

删除对ToString()调用的需求

string actionName = ControllerContext.RouteData.GetRequiredString("action");
string controllerName = ControllerContext.RouteData.GetRequiredString("controller");

这是我目前所拥有的:

var actionName = filterContext.ActionDescriptor.ActionName;
var controllerName = filterContext.ActionDescriptor.ControllerDescriptor.ControllerName;

你可以像任何变量一样从动作中获得控制器名或动作名。它们只是特殊的(控制器和动作)，并且已经定义好了，所以你不需要做任何特殊的事情来获取它们，除了告诉你需要它们。

public string Index(string controller,string action)
   {
     var names=string.Format("Controller : {0}, Action: {1}",controller,action);
     return names;
   }

或者你可以在你的模型中包含控制器，动作来获得其中的两个和你的自定义数据。

public class DtoModel
    {
        public string Action { get; set; }
        public string Controller { get; set; }
        public string Name { get; set; }
    }

public string Index(DtoModel baseModel)
    {
        var names=string.Format("Controller : {0}, Action: {1}",baseModel.Controller,baseModel.Action);
        return names;
    }

下面是一些获取信息的扩展方法(它也包括ID):

public static class HtmlRequestHelper
{
    public static string Id(this HtmlHelper htmlHelper)
    {
        var routeValues = HttpContext.Current.Request.RequestContext.RouteData.Values;

        if (routeValues.ContainsKey("id"))
            return (string)routeValues["id"];
        else if (HttpContext.Current.Request.QueryString.AllKeys.Contains("id"))
            return HttpContext.Current.Request.QueryString["id"];

        return string.Empty;
    }

    public static string Controller(this HtmlHelper htmlHelper)
    {
        var routeValues = HttpContext.Current.Request.RequestContext.RouteData.Values;

        if (routeValues.ContainsKey("controller"))
            return (string)routeValues["controller"];

        return string.Empty;
    }

    public static string Action(this HtmlHelper htmlHelper)
    {
        var routeValues = HttpContext.Current.Request.RequestContext.RouteData.Values;

        if (routeValues.ContainsKey("action"))
            return (string)routeValues["action"];

        return string.Empty;
    }
}

用法:

@Html.Controller();
@Html.Action();
@Html.Id();

var routeValues = HttpContext.Current.Request.RequestContext.RouteData.Values;
if (routeValues != null) 
{
    if (routeValues.ContainsKey("action"))
    {
        var actionName = routeValues["action"].ToString();
                }
    if (routeValues.ContainsKey("controller"))
    {
        var controllerName = routeValues["controller"].ToString();
    }
}
