向您咨询下关于asp.net临时模拟windows用户的问题

[ZBZGiGi]

我在vs2005中需要临时用到windows域帐号的权限，网上搜了下，人家说要

[align=left][DllImport("advapi32.dll", SetLastError=true)]
public extern static bool LogonUser(String lpszUsername, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);

[DllImport("kernel32.dll", CharSet=CharSet.Auto)]
public extern static bool CloseHandle(IntPtr handle);

[DllImport("advapi32.dll", CharSet=CharSet.Auto, SetLastError=true)]
public extern static bool DuplicateToken(IntPtr ExistingTokenHandle, int SECURITY_IMPERSONATION_LEVEL, ref IntPtr DuplicateTokenHandle);

public WindowsIdentity ImpersonationUser
{
get
{
WindowsIdentity newId = null;

string[] args={"VASP","tianqing","!wenXiu01"};
IntPtr tokenHandle = new IntPtr(0);
IntPtr dupeTokenHandle = new IntPtr(0);

try
{
if (args.Length < 3)
{
Console.WriteLine("Usage: DomainName UserName Password");
return null;
}

const int LOGON32_PROVIDER_DEFAULT = 0;
const int LOGON32_LOGON_INTERACTIVE = 2;
const int SecurityImpersonation = 2;

tokenHandle = IntPtr.Zero;
dupeTokenHandle = IntPtr.Zero;

bool returnValue = LogonUser(args[1], args[0], args[2],
LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT,
ref tokenHandle);

if (false == returnValue)
{
Console.WriteLine("LogonUser failed with error code : {0}",
Marshal.GetLastWin32Error());
}

Console.WriteLine("Before impersonation: "
+ WindowsIdentity.GetCurrent().Name);

bool retVal = DuplicateToken(tokenHandle, SecurityImpersonation, ref dupeTokenHandle);
if (false == retVal)
{
CloseHandle(tokenHandle);
Console.WriteLine("Exception in token duplication.");
return null;
}

newId = new WindowsIdentity(tokenHandle);
WindowsImpersonationContext impersonatedUser = newId.Impersonate();

Console.WriteLine("After impersonation: "
+ WindowsIdentity.GetCurrent().Name);

impersonatedUser.Undo();

Console.WriteLine("After Undo: " + WindowsIdentity.GetCurrent().Name);

if (tokenHandle != IntPtr.Zero)
CloseHandle(tokenHandle);
if (dupeTokenHandle != IntPtr.Zero)
CloseHandle(dupeTokenHandle);
}
catch(Exception ex)
{
Console.WriteLine("Exception occurred. " + ex.Message);
}
return newId;
}
}

可是我在调用
bool returnValue = LogonUser(args[1], args[0], args[2], LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT,ref tokenHandle);
返回false，登录失败

希望您能指点下
