在网页中添加一个GradView，一个Button，一点button将MyStudents表中的数据显示在GradView中(DataSet，DataTable，List（选作）)

---DataSet2.aspx--

</div>

<asp:GridView ID="GridView1" runat="server">

</asp:GridView>

<br />

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />

-------DataSet2.aspx.cs----------

protected void Button1_Click(object sender, EventArgs e)

{

string constr = "Data Source=LOVE-PC\\SQLEXPRESSPC;Initial catalog=School;user id=sa;password=admin";

string sql = "select * from MyStudents";

SqlDataAdapter adpter=new SqlDataAdapter(sql,constr);//内部自动商城connection对象和command对象

#region //Adapter到数据集dataset中

//DataSet ds = new DataSet();

//adpter.Fill(ds);

//GridView1.DataBind();

//GridView1.DataSource = ds.Tables[0];

//GridView1.DataBind();

#endregion

#region Adapter到数据表中Datable

DataTable dt = new DataTable();

//在SqlDataAdapter中会封装sqlconnection,sqlcommand,sqldatareader这些东西

adpter.Fill(0, 10, dt);

#endregion

GridView1.DataSource = dt;

GridView1.DataBind();

}
