NetworkCredenti al and WindowsIdentity

Hi All,

I'm trying to access a web page from C# code. Since I'm
behind a firewall/proxy, I creat a webproxy and
NetworkCredenti al to access the web page. It works fine.

In this way, I have to give the username and password for
creating the NetworkCredenti al object. Is there anyway
that I can get the NetworkCredenti al object from the
logged on user?

Basically the requirement is to supply the same credential
as of the logged in user to the web proxy.

Help!!

regards,
Prathiraj

Prathiraj,

No, you can not. While you can get the username of the person that is
currently logged on, you can not get the password. You will have to get
this from the user themselves.

Hope this helps.

here is an example of usage of CredentialCache .DefaultCredent ials

// Ensure Directory Security settings for default web site in IIS is
"Windows Authentication" .
string url = "http://localhost";
// Create a 'HttpWebRequest ' object with the specified url.
HttpWebRequest myHttpWebReques t =
(HttpWebRequest )WebRequest.Cre ate(url);
// Assign the credentials of the logged in user or the user being
impersonated.
myHttpWebReques t.Credentials = CredentialCache .DefaultCredent ials;
// Send the 'HttpWebRequest ' and wait for response.
HttpWebResponse myHttpWebRespon se =
(HttpWebRespons e)myHttpWebRequ est.GetResponse ();
Console.WriteLi ne("Authenticat ion successful");
Console.WriteLi ne("Response received successfully");

I'm working with the NetworkCredential class. I'm making the correct call and it returns that everything is okay using: NetworkCredential sc = new NetworkCredential("MyAccount", sPassword, myURL); However, I then need to make a call using HTTPS to a URL which changes the password. For example:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
