mvc列表显示筛选 或者模糊查询

在orchard中获取数据实体

 

public List<nonoRecord> Get()
        {
            return this._nonoRecordRepository.Table.ToList();
        }
        public nonoRecord Get(int id)
        {
            return this._nonoRecordRepository.Fetch(c => c.Id == id).FirstOrDefault();
        }
        public nonoRecord Get(string name)
        {
             return this._nonoRecordRepository.Fetch(c => c.Name == name).FirstOrDefault();         
        }
        public List<nonoRecord> mohuGet(string name)
        {
            return this._nonoRecordRepository.Fetch(c => c.Name.Contains(name)).ToList();      
        }

mvc中 lndex页面加上一些筛选功能。通过给Index传递参数来实现筛选，在页面添加一个selectbox来筛选Genre字段，把MovieController的方法改成:

public ViewResult Index( string movieGenre)
 {
      var genre = ( from s in db.Movies
                   orderby s.Genre
                   select s.Genre).Distinct();
      ViewBag.MovieGenre = new SelectList(genre);  //给前台准备下拉列表的数据。
      if (! string .IsNullOrEmpty(movieGenre))
      {
          //筛选
          var movies = from s in db.Movies where s.Genre == movieGenre select s;
          return View(movies);
      }
      return View(db.Movies.ToList());
}

在View页面，添加一个Form，里面放上一个选择框和一个按钮，代码如下:

@ using (Html.BeginForm( "Index" , "Movie" , FormMethod.Get))
{
    <p>Genre: @Html.DropDownList( "MovieGenre" , "全部" )  <input type= "submit" value= "筛选" /></p>
}

效果如下：
