C # Analog Domain logon

If you want to use C # for background domain logons, you need to use the Advapi32.dll assembly. Advapi32.dll is part of an Advanced API Application Interface service library that contains functions related to object security, registry manipulation, and event logging. XP system is generally located in the C:\WINDOWS\system32\ directory, the size of 659KB.

Here is the code that implements the domain login:

public class Simulatedomainservice {public static bool impersonateValidUser (string userName, string domain, S
            Tring password) {//servicecontext.setthreadprincipal ();

            WindowsImpersonationContext impersonationcontext;
            WindowsIdentity tempwindowsidentity;
            IntPtr token = IntPtr.Zero;

            IntPtr tokenduplicate = IntPtr.Zero;
                    if (RevertToSelf ()) {if Logonusera (userName, domain, password, logon32_logon_interactive, Logon32_provider_default, ref token)!= 0) {if (DuplicateToken (toke N, 2, ref tokenduplicate)!= 0) {tempwindowsidentity = new WindowsIdentity (to
                        Kenduplicate);
                        impersonationcontext = Tempwindowsidentity.impersonate (); if (impersonationcontext!= null) {CloseHandle (token);
                            CloseHandle (tokenduplicate);
                        return true; The IF (token!= intptr.zero) CloseHandle (
            token);
            if (tokenduplicate!= IntPtr.Zero) CloseHandle (tokenduplicate);
        return false;

which

impersonateValidUser

This method has three parameters, namely account name, domain name, password. The return value is the Boole type, and if true, the login succeeds or the login fails.

Note: The server needs to be within the domain name of the impersonated login (belonging to the same domain)
