Difference between <% # .....%> and <% = ......%>

<ItemTemplate>
<a href='Reader.aspx?MailID=<%# DataBinder.Eval(Container.DataItem,"MailID") %>&FolderID = <% # DataBinder.Eval (Container.DataItem, "FolderID")%> '> < % = AliasName%>&nbsp; <% = Email%> </a>
</ ItemTemplate>

I know that <% # .....%> is used for data binding, and the meaning of <% = ...%> is not clear.

<% = ......%> Can bind the public members defined in the background

<% = ......%> is equivalent to <% Response.Write ("...");%>

# One is to bind the database field
= One is to bind public variables
My guess

I tried it and found that <% = AliasName%>&nbsp; <% = Email%> in the above code is the same as AliasName&nbsp; Email.

#Only valid in the context of bound data.
= Is Response.Write

# Bind database fields
= Is a public variable in the binding cs file

I tried it. In fact, # has the function of =, which means that wherever <% = ......%> appears, you can also use <% # ......%> instead, the effect is the same.

Not binding, but direct output.
