前台：
<asp:GridView runat="server" AutoGenerateColumns="False" CellPadding="3"
BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" >
<FooterStyle BackColor="White" ForeColor="#000066" />
<Columns>
<asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
<asp:BoundField DataField="姓名" HeaderText="姓名" />
<asp:BoundField DataField="出生日期" HeaderText="邮政编码" />
<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
<asp:BoundField DataField="邮政编码" HeaderText="邮政编码" />
<asp:BoundField DataField="起薪" HeaderText="起薪" />
</Columns>
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" CssClass="ms-formlabel DataGridFixedHeader"/>
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
</asp:GridView>
<asp:Button runat="server" Text="导出" />
读取Excel数据的代码：这个很简单的
private DataSet CreateDataSource()
{
string strCon;
strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("excel.xls") + "; Extended Properties=Excel 8.0;";
OleDbConnection olecon = new OleDbConnection(strCon);
OleDbDataAdapter myda = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", strCon);
DataSet myds = new DataSet();
myda.Fill(myds);
return myds;
}
protected void Button1_Click(object sender, EventArgs e)
{
GridView1.DataSource = CreateDataSource();
GridView1.DataBind();
}
由于时间关系，这个文章先到此。有时间再写，其实还有很多技巧，不过我觉得如果能融汇贯通应该可以举一反三。
