Print all session/post/get variables in ASP.NET page

I am very new to ASP.NET, I'm quite used to PHP (which we unfortunately do not use at work) I'd like to print all the session variab开发者_JAVA百科les. In PHP it's quite easy, I use:

echo '<pre>' . print_r($_SESSION, true) . '</pre>';

for this, but is there an as-easy ASP.NET equivalent?

with box being a label.

foreach (string i in Session.Contents) {
  if (Session[i] != null) {
    box.Text += i + " = " + Session[i].ToString() + "\n";
  }
}

Your easiest route is to just enable tracing. This will show you all of this information automatically. You can do this at the page, or the application level.

Here is a quick tutorial on getting started.

Use HttpRequest.Params:

Gets a combined collection of QueryString, Form, ServerVariables, and Cookies items.
