System.Net.Primitives (in System.Net.Primitives.dll)
The property applies only to NTLM, negotiate, and Kerberos-based authentication.
represents the system credentials for the current security context in which the application is running. For a client-side application, these are usually the Windows credentials (user name, password, and domain) of the user running the application. For ASP.NET applications, the default credentials are the user credentials of the logged-in user, or the user being impersonated.
The supported values for authType are "NTLM", "Digest", "Kerberos", and "Negotiate". This method does not work for HTTP or FTP protocols.
The ICredentials instance returned by cannot be used to view the user name, password, or domain of the current security context.
The following code example uses the property to get the system credentials of the application.
' Assuming "Windows Authentication" has been set as; ' Directory Security settings for default web site in IIS. Dim url As String = "http://localhost" ' Create a 'HttpWebRequest' object with the specified url. Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(url), HttpWebRequest) ' Assign the credentials of the logged in user or the user being impersonated. myHttpWebRequest.Credentials = CredentialCache.DefaultCredentials ' Send the 'HttpWebRequest' and wait for response. Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse) Console.WriteLine("Authentication successful") Console.WriteLine("Response received successfully")
