在 ASP 中，页函数可以在 <% %> 块中声明：

<%
    Sub DoSomething()
        Response.Write "Hello World!"
    End Sub

    DoSomething
%>

在 ASP.NET 中，页函数必须在 <script runat=server> 块中声明：

<script language="C#" runat=server> void DoSomething() { Response.Write("Hello World!"); } </script> <% DoSomething(); %> <script language="VB" runat=server> Sub DoSomething() Response.Write ("Hello World!") End Sub </script> <% DoSomething() %> <script language="JScript" runat=server> function DoSomething() : void { Response.Write("Hello World!"); } </script> <% DoSomething(); %> C# VB JScript

在 ASP 中，可以用 <% %> 块声明页呈现函数：

<% Sub RenderSomething() %>
       <font color="red"> Here is the time: <%=Now %> </font>
<% End Sub %>

<%
   RenderSomething
   RenderSomething
%>

在 ASP.NET 中，这必须重写：

<script language="C#" runat=server> void RenderSomething() { Response.Write("<font color=red> "); Response.Write("Here is the time: " + DateTime.Now); } </script> <% RenderSomething(); RenderSomething(); %> <script language="VB" runat=server> Sub RenderSomething() Response.Write("<font color=red> ") Response.Write("Here is the time: " & Now) End Sub </script> <% RenderSomething() RenderSomething() %> <script language="JScript" runat=server> function RenderSomething() : void { Response.Write("<font color=red> "); Response.Write("Here is the time: " + DateTime.Now); } </script> <% RenderSomething(); RenderSomething(); %> C# VB JScript
