Question

我正在使用asp.net mvc5并尝试在我的表格上方添加一个文本框来搜索表格中的项目。在我看来，我有

@using (Html.BeginForm())
{
   <p>
       Find by Start/End Point @Html.TextBox("SearchString")
       <input type="submit" value="Search" />
   </p>
}

然后在我的控制器中

public ActionResult Index(string sortOrder, string searchString)
{
    var lift = from l in db.Lifts select l;
    if (!String.IsNullOrEmpty(searchString))
    {
        lift = lift.Where(l => l.StartPoint.Contains(searchString)
                                || l.EndPoint.Contains(searchString));
    }
        return View(lifts.ToList());
    }
}

但是每次都会返回相同的表格。这可能是愚蠢的我做错了但我无法看到。

尝试使用：

@using (Html.BeginForm("Index","ControllerName",new { sortOrder = "Desc/Asc" },FormMethod.Post))
                    {
                        <p>
                        Find by Start/End Point @Html.TextBox("SearchString")
                            <input type="submit" value="Search" /></p>
                    }

行动代码： -

public ActionResult Index(string sortOrder, string SearchString)
        {
            var lift = from l in db.Lifts select l;
            if (!String.IsNullOrEmpty(SearchString))
            {
                lift = lift.Where(l => l.StartPoint.Contains(SearchString)
                                       || l.EndPoint.Contains(SearchString));
            }
             return View(lifts.ToList());
            }
        }

为什么我的搜索框无法返回任何结果？
