how to Embedded Code Blocks in ASP.NET Web Pages?

Question

where we use <%@ %> <%= %> <%# %> etc. what else asp tags can be added in asp.net web pages?

Answer 1

<%@ %> - page directives, Register control
<%= %> - for the server code  
<%# %> - for the eval kind of function its also for the server code

Answer 2

<%%> is short hand for:

<script runat="server">
</script>

Anyting inside the <% and %> is server side code.

The other variants are also shortcuts:

• <%@%> is a page directrive
• <%=%> is short for Response.Write
• <%:%> is short for Response.Write, adding html encoding (introduced with .NET 4.0)
• <%#%> is a binding expression

This page is a good reference to all these.
