Question

我是MVC的新人。我想传递参数adminNo，但它总是为空。过去几天我一直坚持这个问题。

控制器

public ActionResult PledgeForm(string adminNo)
{
    var result = new StudentJournalQuery().GetStudentInfo(adminNo);
    return View(result);
}

RouteConfig

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
      name: "Default1",
      url: "{controller}/{action}/{adminno}",
      defaults: new { controller = "Home", action = "Index", adminno = UrlParameter.Optional }
    );

ActionMethod

<a href="@Url.Action("PledgeForm", "ManageSipStudentJournal", new {adminNo = @Model.adminNo, area= string.Empty})">View Pledge Form</a>

SQL查询以下是SQL查询

public StudentJournalSummary GetJournalSummary(string adminNo)
{
    var StudentJournalSummary = new StudentJournalSummary();
    const string _CountSql =
        @"select count(sjd.WeekNo) TotalWeek, sum(sj.TotalDaysRecord) TotalDaysRecord, count(case sjd.JournalStatusCode when  'D' then 1 else null end) PendingComplete from StudentJournalDate sjd left outer join 
        (select sj.WeekNo, 
         case when RTRIM(sj.Day1Journal) = '' or sj.Day1Journal is null then 0 else 1 end +
         case when RTRIM(sj.Day2Journal) = '' or sj.Day2Journal is null then 0 else 1 end +
         case when RTRIM(sj.Day3Journal) = '' or sj.Day3Journal is null then 0 else 1 end +
         case when RTRIM(sj.Day4Journal) = '' or sj.Day4Journal is null then 0 else 1 end +
         case when RTRIM(sj.Day5Journal) = '' or sj.Day5Journal is null then 0 else 1 end +
         case when RTRIM(sj.Day6Journal) = '' or sj.Day6Journal is null then 0 else 1 end +
         case when RTRIM(sj.Day7Journal) = '' or sj.Day7Journal is null then 0 else 1 end as TotalDaysRecord 
         from StudentJournal sj ) as sj  on sjd.WeekNo = sj.WeekNo";

    using (var connection = Db.SqlServer())
    {
        StudentJournalSummary = connection
         .Query<StudentJournalSummary>(_CountSql, new { adminNo }).FirstOrDefault();
    }

    return StudentJournalSummary;
}

你忘记在Model.adminNo中删除@它不需要已经在@ Url.Action中定义了

<a href="@Url.Action("PledgeForm", "ManageSipStudentJournal", new {adminNo = Model.adminNo, area= string.Empty})">View Pledge Form</a>
