ASP.NET With C#: IIS Code Delimiters

	IIS Code Delimiters

Description

When developing your web pages, you can include HTML and scripting code in the same file but you must distinguish them. While HTML uses its own tags, to show the beginning of an Active Server Pages script, you must type <%, which is called a delimiter. To show the end of that section, you must type %>, which is also called a delimiter.

Here is an example:

<html>
<head>

<title>Exercise</title>

</head>
<body>

<%    %>

</body>
</html>

most of the time, you will write each delimiter on its own line. Here is an example;

<html>
<head>

<title>Exercise</title>

</head>
<body>

<%

%>

</body>
</html>

This technique is not a rule. Sometimes it simply makes your code easier to ready. Everything between <% and %> is part of the script and is reserved only for the script.

Although we created only one delimiting section, you can create as many delimiting sections as you want. Here are examples:

<html>
<head>

<title>Exercise</title>

</head>
<body>

<% %>

<% %>

<% %>

</body>
</html>

Of course, you can create the sections where each delimiter is on its own line:

<html>
<head>

<title>Exercise</title>

</head>
<body>

<% %>

<%

%>

<% %>

<%

%>

</body>
</html>

Between an opening delimiter <% and a closing delimiter %>, you can add the necessary ASP code, which can consist of ASP code, HTML code, and others. Before an opening delimiter <% or after a closing delimiter %>, you can add HTML code as you want but no ASP code:

<html>
<head>

<title>Exercise</title>

</head>
<body>
