What is the difference between <% %> and <%=%>?

I have seen samples with "<%#", "<%=" and "<%". First of all, is there a name for these things? Second, where can I find a reference that tells what the different versions do? I have tried searching, but can't find anything.

What is the difference between <% %> and <%=%>?

The difference between <% %> and <%= %> is discussed here. In essence the <%= %> variant is used used to output the result of an expression, while the version without the = is just used to execute some code.

The <%# %> version is used for data binding, and its use is discussed on this Microsoft support page.

The official name for this syntax is Server-Side Scripting Delimiters. Much more info can be found in the answers to question 649428.
