Select Date from DateTime database filed using Entity Framework in ASP.Net MVC

hi;

I have Datetime field and its stored to table like 2020-12-08 15:14:45

When I call like this

var tbl=db.Customer.First(); 

tbl.SENDATE = Convert.ToDateTime(tbl.SENDATE.ToString("yyyy-mm-DD")),

the result not like 2020-12-08 

      DataSourceResult result = data.ToDataSourceResult(request, x => new EntityModel
      {
        DURUMU = x.DURUMU,
        DEFINITION_ = x.DEFINITION_,
        TAXNR = x.TAXNR,
        SENDATE = Convert.ToDateTime(x.SENDATE.ToString("yyyy-MM-dd")),
        RESPONDATE = Convert.ToDateTime(Convert.ToDateTime(x.RESPONDATE).ToString("yyyy-MM-dd")),
        SENDERINFO = x.SENDERINFO,
        RESPONDINFO = x.RESPONDINFO,
        INVAMOUNT = x.INVAMOUNT,
        PRICE = x.PRICE,
        APPROVER = x.APPROVER
 
      });
      return Json(result);

its showing 11.12.2020

this is shows: 2020-12-07 so good.

var test = DateTime.ParseExact(data.SENDATE.ToString("dd.MM.yyyy hh:mm:ss"), "dd.MM.yyyy hh:mm:ss",
          CultureInfo.InvariantCulture).ToString("yyyy-MM-dd");

 this is shows : 17.12.2020 00:00:00

DateTime test2 = Convert.ToDateTime(test);

I think the problem occur after convert. I want to escape hh:mm:ss
