Can you tell the differences between <%= %>, <%# %> and <%$ %> ASP.NET expressions?

Question

Can you briefly list the differences between <%= %>, <%# %> and <%$ %> by giving a simple example?

Maybe one tha

Answer 1

<% %>

<% this.CallMethod() %> - Basic code block that executes the statements inside.

---

<%= %>

<%= "text" %> - Embedded code syntax. Same as writing <% Response.Write("text") %>.

---

<%: %>

<%: "text" %> - Same as above except it's a shorthand for <%= Server.HtmlEncode("text") %>. This was introduced in ASP.NET 4 and is the default syntax used.

---

<%# %>

<%# Eval("ColumnName") %> - Used for databinding.

---

<%$ %>

<%$ AppSettings: settingName %> - The expression syntax has a prefix such as AppSettings, ConnectionStrings, or Resources and then a : followed by the actual expression. It can be used as a shorthand to access resources inline. You can even create your own syntax used here (Thanks @Thomas Levesque). Also see MSDN for more info.

---

<%@ %>

<%@ Page language="C#" %> - The directive syntax useful for page/control settings.

---

<%-- --%>

<%-- This is a comment --%> - Server-side comment syntax. This differs from the HTML <!-- a comment --> syntax in that it won't be rendered in the output.
