รบกวนดู code ให้หน่อยครับ รับค่าวันที่ลงฐานข้อมูลมาแล้ว แต่ค่าที่แสดงไม่ตรงกัน

string sqlString = "INSERT INTO tb_profile(IdNumber,Name,Surname,EmailAddress,Phone,Sex,DateAdd, Address,District,Prefecture,Province,Zipcode)VALUES(@IdNumber, @Name,@Surname,@EmailAddress,@Phone,@Sex,@DateAdd,@Address,@District,@Prefecture,@Province,@Zipcode)";
        SqlCommand comm = new SqlCommand(sqlString);
        comm.Connection = objConn;
        comm.Parameters.AddWithValue("@IdNumber",TxtIdnumber.Text);
        comm.Parameters.AddWithValue("@Name", TxtName.Text);
        comm.Parameters.AddWithValue("@Surname", TxtSurname.Text);
        comm.Parameters.AddWithValue("@EmailAddress", TxtEmailAddress.Text);
        comm.Parameters.AddWithValue("@Phone", TxtPhone.Text);
        comm.Parameters.AddWithValue("@Sex", RBLSex.Text);
        comm.Parameters.AddWithValue("@DateAdd", TxtDateAdd_CalendarExtender.ClearTime);
        comm.Parameters.AddWithValue("@Address", TxtAddress.Text);
        comm.Parameters.AddWithValue("@District", TxtDistrict.Text);
        comm.Parameters.AddWithValue("@Prefecture", TxtPrefecture.Text);
        comm.Parameters.AddWithValue("@Province", TxtProvince.Text);
        comm.Parameters.AddWithValue("@Zipcode", TxtZipcode.Text);
