LINQ to SQL 第五集 - 如何比對日期欄位的資料
取得訂單日期為 1998 年的資料,當然也可以比對 月(Month) 或 日(Day)。
using System;
using System.Linq;
using System.Windows.Forms;
namespace LinqToSql
{
public partial class MainForm : Form
{
public MainForm()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
NorthwindDataContext db = new NorthwindDataContext();
var q = from o in db.Orders
where o.OrderDate.Value.Year == 1998
select o;
dataGridView1.DataSource = q.ToList();
}
}
}
執行結果:
Enjoy.
