Here is my obscure problem. I've got a page where a some checkboxes get added dynamically by javascript like so.

[input type="checkbox" name="extra" value="uno" /] Uno
[input type="checkbox" name="extra" value="dos" /] Dos
[input type="checkbox" name="extra" value="tres" /] Tres

string extras = HttpContext.Current.Request.Form["extras"].Split(",");
// extras[0] == "uno"
// extras[1] == "dos"
// extras[2] == "tres"

[input type="checkbox" name="extra" value="first item" /]First Item
[input type="checkbox" name="extra" value="Second item, with a comma" /]Second item, with a comma
[input type="checkbox" name="extra" value="third item" /]third item

string extras = HttpContext.Current.Request.Form["extras"].Split(",");
// extras[0] == "first item"
// extras[1] == "second item"
// extras[2] == "with a comma"
// extras[3] == "third item"

public static ICollection FormVars(System.Web.HttpRequest request, string varName) {
	StreamReader sr = new StreamReader(request.InputStream);
	string post = sr.ReadToEnd();
	sr.Close();
	ArrayList values = new ArrayList();

	string[] labelValues = post.Split('&');
	foreach(string lv in labelValues) {
		if (lv.StartsWith(varName)) {
			string val = lv.Substring(varName.Length + 1); // varName=
			values.Add(System.Web.HttpUtility.UrlDecode(val));
		}
	}
	return values;
}



ICollection extras = Utils.FormVars(HttpContext.Current.Request, "extra");
