我有一个ASP.NET C＃项目，<％= myfunction（）;有什么区别？ ％>和<％＃myfunction（）％>？

Question

protected string myfunction() {
   return "abc";
}

In one of my pages I can show the "abc" in the webpage by using <%# myfunction() %> . But in another page it doesn't work unless I use <%=myfunction(); %> <%=myfunction(); %> instead.

What is the difference and why?

Thanks a lot!

Answer 1

<%= myfunction(); %> <%= myfunction(); %> would be used to output the return value of myfunction in a page.

<%# myfunction(); %> <%# myfunction(); %> would be used to output the return value of myfunction in a control that is data bound (for example, inside an asp repeater control).

Take a look at this overview for more information on data binding.
