How do I force a postback in the codebehind?

You need to call a javascript method. myForm.submit() will do.
location.reload() also will. Why do you want to do it in the code behind?
Why not to put a few lines if javascript in the .aspx page?

I am checking if a certain object is null and if it is I need to go back to ther server and get this object can I force a postback in the code behind
and if so how?

your question makes no sense. codebehind is server processing, so there is
no need of a postback, you are already there.

I'm not really sure what you mean, but if your in the codebehind there is no
way to execute postback but there is trick there by rendering a javascript
that will resubit the form:

....
....

if(requirePostback)
{
Response.Write("<script>document.forms[0].submit();</script>");
}

...
....

the statement above will reexecute submit.
