使用HTML或C#在GridView中更改列名

<asp:GridView ID="GridView1" runat="server">
   <Columns>
        <asp:BoundField DataField="ID" HeaderText="编号" />
        <asp:BoundField DataField="Name" HeaderText="姓名" />
        <asp:BoundField DataField="Age" HeaderText="年龄" />
    </Columns>
</asp:GridView>

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        e.Row.Cells[0].Text = "编号";
        e.Row.Cells[1].Text = "姓名";
        e.Row.Cells[2].Text = "年龄";
    }
}
