.net - Formatting HTML As Text?

UPDATE 2:

In this section, I am trying to manually add in tabs and line spaces so the string is formatted when displayed via the pre tag. But this does not work.

objStringBuilder.Append("<div>" & Environment.NewLine)
objStringBuilder.Append(vbTab & "<div>some text</div>" & Environment.NewLine)
objStringBuilder.Append("</div>" & Environment.NewLine)
Return "<pre>" & Server.HtmlEncode(objStringBuilder.ToString) & "</pre>"

UPDATE 1:

I have tried the following, but it does not work:

return "<pre>" & Server.HtmlEncode("<div><div>some text</div></div>") & "</pre>"

I want it to display something like this

<div>
<div>some text</div>
</div>

But it's diplaying like this, which is expected:

<div><div>some text</div></div>

I don't know how to get spaces, tabs, carriage returns into that string which are recognizable by the pre tag, as environment.newline and/or vbtab make no difference.

ORIGINAL QUESTION:

Is it possible to display HTML as text on your page in a formatted manner? For example, it should contain white spaces, tabs etc etc for readability purposes:

From another question, I have learned how to display HTML as text as follows:

Server.HtmlEncode("<div>Some text</div>");
