asp.net mvc - Fake a form submission with C# WebClient

Question

I need to call a web and retrieve the resulting data from the model in my asp.net mvc application. When accessed on the web, the form looks like this:

<form id="textEntryForm" name="textEntryForm" method="post" action="/project/evaluate_to_pdf">
            <textarea id="p" rows="20" name="p" cols="132"/><br/>   
            <input type="button" value="parse" name="do_parse" onclick="new Ajax.Updater('parsedProject','/project/parse',{asynchronous:true,evalScripts:true,on404:function(e){alert('not found!')},parameters:Form.serialize(this.form)});return false"/>
            <input type="button" value="evaluate_to_html" name="do_evaluate_to_html" onclick="new Ajax.Updater('parsedProject','/project/evaluate_to_html',{asynchronous:true,evalScripts:true,on404:function(e){alert('not found!')},parameters:Form.serialize(this.form)});return false"/>
            <input type="button" value="evaluate" name="do_evaluate" onclick="new Ajax.Updater('parsedProject','/project/evaluate',{asynchronous:true,evalScripts:true,on404:function(e){alert('not found!')},parameters:Form.serialize(this.form)});return false"/>
            <input type="button" value="evaluate to pdf source" name="do_evaluate_to_pdf_source" onclick="new Ajax.Updater('parsedProject','/project/evaluate_to_pdf_source',{asynchronous:true,evalScripts:true,on404:function(e){alert('not found!')},parameters:Form.serialize(this.form)});return false"/>
            <input type="submit" id="do_evaluate_to_pdf" value="evaluate_to_pdf" name="do_evaluate_to_pdf"/>
        </form>

I need to pass the data that would be entered into textarea id="p". How do add that in, using a WebClient to connect?

Thanks!

Edit This isn't for testing purposes, I need to retrieve the data for use in my application.
