ASPX page response syntax

In the past I have always worked from the code behind page in ASP.NET and emitting all of my markup from that area.

I am now learning MVC and am working in the .ASPX page direc开发者_开发技巧tly.

The following statements can be written...

<%= Html.Label("Test") %>
<%: Html.Label("Test")%>
<% Html.Label("Test"); %>

The first two emit the word 'Test', while the 3rd doesn't do anything. Yet no errors are thrown.

I seem to recall <%= is shorthand for <% Response.Write("") %>. Is <%: the same shortcut?

I suppose the 3rd statment runs, but simply returns a string that is discarded.

You are right about 1 and 3. 2 does as one, but it html escapes the output.
