c# - 如何使用 asp.net mvc 和 razor 模板引擎从 c# 中的路由名称获取 URL？

Question

我正在尝试获取 Razor 模板内已知路由名称的 url。

这是我的部分观点

@model ScripterEngine.ViewModels.CampaignViewModel

<script type="text/javascript">

    function logTime(stage, status, async){

        var target = "@UrlHelper.RouteUrl("timetracker.clockin")";

        var postData =
        {
            'campaign_id': @Model.id,
            'agent_id': is_system_agentid.value,
            'log_id': is_attr_calldata.tracker_id,
            'stage_name': stage
        };

        if( status == 'out'){
            target = "@UrlHelper.RouteUrl("timetracker.clockout")";
        }

        if( async !== false){
            async = true;
        }

        $.ajax({
            type: 'POST',
            url: target,
            data: postData,
            async: async,
            dataType: "json",
            error: function( jqXHR, textStatus, errorThrown ){

                alert('clock ' + status + ' failed!' + jqXHR.status );
            },
            success: function(data){

                if(data && data.id && status != 'out'){
                    is_attr_calldata.tracker_id  = data.id;
                }

            }
        });
    }

</script>   

这是我的路线图

        //Timetracker - ClockIn
        routes.MapRoute(
            "timetracker.clockin",
            "timetracker/clockin",
            new { controller = "TimeTracker", action = "ClockIn" }
        );

        //Timetracker - ClockOut
        routes.MapRoute(
            "timetracker.clockout",
            "timetracker/clockout",
            new { controller = "TimeTracker", action = "ClockOut" }
        );

但是，在启动程序并导航到路由后出现编译错误。

Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0120: An object reference is required for the non-static field, method, or property 'System.Web.Mvc.UrlHelper.RouteUrl(string)'

错误点在此行

var target = "@UrlHelper.RouteUrl("timetracker.clockin")";

如何从给定的路由名称中正确获取 Url？

Answer 1

UrlHelper 在 View 中显示为 @Url - WebViewPage 的代码具有:

public UrlHelper Url { get; set; }

尝试:

var target = '@Url.RouteUrl("timetracker.clockin")';
