public partial class Form3 : Form
{ //缓存类
System.Web.Caching.Cache cache;
public Form3()
{
InitializeComponent();
string SQL = "select top 1000 * from infomation";
DataTable datatable = DBHelper.GetDataTable(SQL, ConnType.Menu);
dataGridView1.DataSource = datatable;
cache = System.Web.HttpRuntime.Cache;
cache.Insert("infomation", datatable);
}
private void button1_Click(object sender, EventArgs e)
{
if (cache != null) {
DataTable table = cache["infomation"] as DataTable;
dataGridView2.DataSource = table;
}
}
