code behind:

protected string People_Name
{
get
{
return "yh";
}
}


.aspx:

<asp:Button id="Button1" runat="server" Text='Button1'></asp:Button><BR>
你好，<%=People_Name%><BR>
<asp:TextBox id="TextBox1" runat="server" Width="400px" Height="264px" TextMode="MultiLine"></asp:TextBox>


看出和数据绑定表达式有什么不同了没有？
