Inserting NULL values for Both SQL and LINQ

SQL


SqlDateTime myNullDate;

myNullDate = SqlDateTime.Null;


if (txtOrderCreated.Text == "")
    {
        cmd.Parameters.Add(new SqlParameter("@OrderCreated ", SqlDbType.DateTime)).Value = myNullDate;
    }
else
    {
        cmd.Parameters.Add(new SqlParameter("@OrderCreated ", SqlDbType.DateTime)).Value = DateTime.Parse(txtOrderCreated.Text);
    }



LINQ



var x = new tbl_Order();

if (txtOrderCreated.Text != "")
    {
        x.OrderCreated = DateTime.Parse(txtOrderCreated.Text);
    }
else
    {
        x.OrderCreated = null;
    }
