爲什麼我的搜索框不會返回任何結果？

Question

我使用asp.net mvc5並試圖在我的表上方添加一個文本框來搜索表中的項目。在我看來，我有

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

然後在我的控制器

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()); 
    } 
} 

但是它每次都返回同一個表。這可能是一件愚蠢的事我做錯了，但我看不到。

嘗試使用這樣的：

@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> 
        } 

行爲代碼： -

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()); 
      } 
     }
