c# - 如何检索日期等于或不等于输入类型 date .value 和从 asp.net 中的数据库日期列

Question

我想从数据库日期列中检索输入类型日期，我该怎么做，我想数据库日期列不存在或不等于不显示数据

在 HTML 中

<div class="col-md-12 col-sm-12 text-center">
    <label for="start">Günün Menüsü için Tarih Seçiniz:</label>

    <input type="date" runat="server" id="datee" name="trip-start"
           value="2018-07-22"
           min="2018-01-01" max="2018-12-31">
</div>

在 aspx.cs

if (datee.Value.ToString() == "Tarih".ToString())
        {
            SqlConnection conn = new SqlConnection();
            conn.ConnectionString = "Server=.;Database=MerkezCafeDB;Integrated Security = True";
            conn.Open();

            SqlDataAdapter adapter = new SqlDataAdapter("Select * from GununMenusu", conn);
            DataTable datatbl = new DataTable();
            adapter.Fill(datatbl);
            Repeater2.DataSource = datatbl;
            Repeater2.DataBind();
            conn.Close();
            
        }
        else
        {
            
        }

顺便说一句，对不起我的英语不好
