Question

我正在开发一个c＃mvc应用程序，我在我的应用程序中使用这个javascript日历：http://fullcalendar.io/。我展示的事件是法庭听证会。以下是我服务中方法的一部分，它构建了法庭听证会的陈述：

var obj = new
{
    id = hearing.id,
    title = string.Format("Hearing ({0} - {1}) in the case №{2}/{3}", hearing.HearingStart.Value.ToString("H:mm"), hearing.HearingEnd.Value.ToString("H:mm"), hearing.CaseNumber, hearing.CaseYear),
    start = hearing.HearingStart.Value.ToString("yyyy-MM-dd HH:mm:ss"),
    end = hearing.HearingEnd.Value.ToString("yyyy-MM-dd HH:mm:ss")
};

在该方法的这一行中：

title = string.Format("Hearing ({0} - {1}) in the case №{2}/{3}", hearing.HearingStart.Value.ToString("H:mm"), hearing.HearingEnd.Value.ToString("H:mm"), hearing.CaseNumber, hearing.CaseYear)

我想让caseNumber成为指向此网站的ActionLink：http://93.152.175.226/Cases/Details/327688

我在google和stackoverflow.com中查找了一些示例，这些示例显示了在c＃代码中使用ActionLink的正确语法（不在视图中，但在服务方法中），但没有找到任何。

以下是控制器中的方法：

public ActionResult GetHearingsForJudgePanel(string id, int? month = null, int? year = null, int? caseNumber = null, int? caseYear = null)
{
    if (!Request.IsAjaxRequest())
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);

    int currentMonth;
    int currentYear;
    DateTime currentDate = DateTime.Now;
    EventService service = new EventService();
    IEnumerable<object> data;

    if (id == "")
    {
        id = null;
    }

    if (month.HasValue)
        currentMonth = month.Value;
    else
        currentMonth = currentDate.Month;

    if (year.HasValue)
        currentYear = year.Value;
    else
        currentYear = currentDate.Year;

    data = service.GetHearingsForJudgePanel(id, currentMonth, currentYear, caseNumber, caseYear);

    return Json(data, JsonRequestBehavior.AllowGet);
}

这是我的服务方法： public IEnumerable GetHearingsForJudgePanel（string id，int month，int year，int？caseNumber，int？caseYear） { List result = new List（）; 列出听证会=新列表（）;

        string constr = System.Configuration.ConfigurationManager.ConnectionStrings["DapperConnection"].ToString();

        con = new SqlConnection(constr);

        hearings = con.Query<HearingsForCalendarViewModel>("GetHearingsForCalendar", new { id, month, year, caseNumber, caseYear }, commandType: CommandType.StoredProcedure).ToList();

        const string protocol = "http://";
        const string baseAddress = "93.152.175.226";
        const string path = "/Cases/Details/";

        foreach (var hearing in hearings)
        {
            var link = $"<a href=\"{protocol}{baseAddress}{path}{hearing.caseId}\">{he‌aring.CaseNumber}</a‌>";
                var obj = new
                {
                    id = hearing.id,
                    title = string.Format("Hearing({0} - {1}) in the case №{2}/{3}", hearing.HearingStart.Value.ToString("H:mm"), hearing.HearingEnd.Value.ToString("H:mm"), link, hearing.CaseYear),

                    start = hearing.HearingStart.Value.ToString("yyyy-MM-dd HH:mm:ss"),
                    end = hearing.HearingEnd.Value.ToString("yyyy-MM-dd HH:mm:ss")
                };

                result.Add(obj);

        }

        return result;
    }

在MVC控制器中，您可以通过基类UrlHelper的{{1}}属性访问Url：

System.Web.Mvc.Controller

如果链接应该构建在不从var link = Url.Action("Details", "Cases", new { id = caseNumber });继承的类中（例如ViewModel或Service），则可以通过传递当前的RequestContext来创建System.Web.Mvc.Controller：

UrlHelper

或者您将UrlHelper从Controller注入服务方法。

如何在不继承Controller的类中创建actionlink？
