on clicking search,nothing happen我试图首先使用asp.net mvc 5代码中的date属性过滤细节。 但它不起作用。 我只创建了一个模型类，代码首先从中生成一个控制器并查看它。 现在我想过滤关于日期的索引页面上的细节。 这是我正在使用的代码。
模特课： -
public class Meeting
{
public int MeetingID { get; set; }
public String Name { get; set; }
public String designation { get; set; }
[Display(Name = "9:00 - 10:00")]
public String NineToTen { get; set; }
[Display(Name = "10:00 - 11:00")]
public String TenToEleven { get; set; }
[Display(Name = "11:00 - 12:00")]
public String ElevenToTwelve { get; set; }
[Display(Name = "12:00 - 1:00")]
public String TwelveToOne { get; set; }
[Display(Name = "1:00 - 2:00")]
public String OneToTwo { get; set; }
[Display(Name = "2:00 - 3:00")]
public String TwoToThree { get; set; }
[Display(Name = "3:00 - 4:00")]
public String ThreeToFour { get; set; }
[Required(ErrorMessage = "Please Enter the Date")]

答案 0 :(得分：0)
您将返回完整的数据集，而不是返回已过滤的数据。您可能想尝试以下行 -
return View(Meeting);
