Hello,

Using C# I'm using a 'webbrowser' to navigate to particular URLs.
However, when I clicked on a certain button on the browser, a new page is opened and I need to get the session id (in other words, the part after the question mark) of this page.

The URL of the new page is below.
www.fbwebpos.com/finans/report/transaction.search?<b>OWASP_CSRFTOKEN=ZSOT-CPUM-N32D[^]

webBrowser.Url.ToString() only returns: www.fbwebpos.com/finans/report/transaction.search[^]

webBrowser1.Url.Query.ToString() returns empty.

Thank you.

Thanks for your answer. However, I'm working on a windows form application and if I'm not mistaken your suggestion is valid for web projects.

Add a handler for 'Navigated' event:

C#

private void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
    string query = e.Url.Query;
}

This will give you query string part of URL including the question mark at start.

Alternatively you can use:

C#

webBrowser1.Document.Url.Query

but you'll have to make sure the browser finished loading the document.
