HttpRequest.LogonUserIdentity Property
Assembly: System.Web (in system.web.dll)
The LogonUserIdentity property exposes the properties and methods of the WindowsIdentity object for the currently connected user to Microsoft Internet Information Services (IIS). The instance of the WindowsIdentity class that is exposed by LogonUserIdentity tracks the IIS request token and provides easy access to this token for the current HTTP request being processed inside of ASP.NET. An instance of the WindowsIdentity class is automatically created so it does not need to be constructed to in order to gain access to its methods and properties.
The following code example shows how to retrieve the LogonUserIdentity property for the current user and write out the values of each item in a text file. Place this code on the ASP.NET page referenced by the form's ACTION attribute.
<%@ Page Language="C#" %> <%@ import Namespace="System.IO" %> <script runat="server"> /* NOTE: To use this sample, create a c:\temp folder, * add the ASP.NET account (in IIS 5.x <machinename>\ASPNET, * in IIS 6.x NETWORK SERVICE), and give it write permissions * to the folder.*/ private const string INFO_DIR = @"c:\temp\"; private void Page_Load(object sender, System.EventArgs e) { // Validate that user is authenticated if (!Request.LogonUserIdentity.IsAuthenticated) Response.Redirect("LoginPage.aspx"); // Create a string that contains the file path string strFilePath = INFO_DIR + "CS_Log.txt"; Response.Write("Writing log file to " + strFilePath + "..."); // Create stream writer object and pass it the file path StreamWriter sw = File.CreateText(strFilePath); // Write user info to log sw.WriteLine("Access log from " + DateTime.Now.ToString()); sw.WriteLine("User: " + Request.LogonUserIdentity.User); sw.WriteLine("Name: " + Request.LogonUserIdentity.Name); sw.WriteLine("AuthenticationType: " + Request.LogonUserIdentity.AuthenticationType); sw.WriteLine("ImpersonationLevel: " + Request.LogonUserIdentity.ImpersonationLevel); sw.WriteLine("IsAnonymous: " + Request.LogonUserIdentity.IsAnonymous); sw.WriteLine("IsGuest: " + Request.LogonUserIdentity.IsGuest); sw.WriteLine("IsSystem: " + Request.LogonUserIdentity.IsSystem); sw.WriteLine("Owner: " + Request.LogonUserIdentity.Owner); sw.WriteLine("Token: " + Request.LogonUserIdentity.Token); // Close the stream to the file. sw.Close(); } </script>
