导读：核心代码： [DllImport("Advapi32.DLL")]static extern bool ImpersonateLoggedOnUser(IntPtr hToken);[DllImport("Advapi32.DLL")]static extern bool RevertToSelf();const int LOGON32_PROVIDER_DEFAULT = 0;const int LOGON32_LOGON_NEWCREDENTIALS = 9;

核心代码：

[DllImport("Advapi32.DLL")]
static extern bool ImpersonateLoggedOnUser(IntPtr hToken);
[DllImport("Advapi32.DLL")]
static extern bool RevertToSelf();
const int LOGON32_PROVIDER_DEFAULT = 0;
const int LOGON32_LOGON_NEWCREDENTIALS = 9;//域ò控?中D的?需è要a用?:Interactive = 2
private bool disposed;
/// <summary>
/// 登?录?
/// </summary>
/// <param name="sUsername"&gt;用?户§名?</param>
/// <param name="sDomain"&gt;域ò名?，?如?果?不?在ú域ò中D就í使1用?机ú器÷IP地?址·</param>
/// <param name="sPassword"&gt;密ü码?</param>
public IdentityScope(string sUsername,string sDomain,string sPassword)
{
  // initialize tokens
  IntPtr pExistingTokenHandle = new IntPtr(0);
  IntPtr pDuplicateTokenHandle = new IntPtr(0);
  try
  {
    // get handle to token
    bool bImpersonated = LogonUser(sUsername,sDomain,sPassword,LOGON32_LOGON_NEWCREDENTIALS,LOGON32_PROVIDER_DEFAULT,ref pExistingTokenHandle);
    if (true == bImpersonated)
    {
      if (!ImpersonateLoggedOnUser(pExistingTokenHandle))
      {
        int nErrorCode = Marshal.GetLastWin32Error();
        throw new Exception("ImpersonateLoggedOnUser error;Code=" + nErrorCode);
      }
    }
    else
    {
      int nErrorCode = Marshal.GetLastWin32Error();
      throw new Exception("LogonUser error;Code=" + nErrorCode);
    }
  }
  finally
  {
    // close handle(s)
    if (pExistingTokenHandle != IntPtr.Zero)
      CloseHandle(pExistingTokenHandle);
    if (pDuplicateTokenHandle != IntPtr.Zero)
      CloseHandle(pDuplicateTokenHandle);
  }
}
protected virtual void Dispose(bool disposing)
{
  if (!disposed)
  {
    RevertToSelf();
    disposed = true;
  }
}
public void Dispose()
{
  Dispose(true);
}

}

第二个参数是域名，有域名的话写域名，没有域名写目标机器的IP就可以了
