WindowsIdentity identity = new WindowsIdentity(accessToken); 
WindowsImpersonationContext context = identity.Impersonate(); 

... 
context.Undo(); 

我在哪里申报管理员用户名和密码?用用户名和密码模拟?

的accessToken PARAM并不能帮助我太多...

我必须导入DLL的呢?

你需要得到用户的令牌这里) 在c#

外部方法声明,想象它在C#中。使用P /从ADVAPI32.DLL调用LogonUser

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

例子:

IntPtr userToken = IntPtr.Zero; 

bool success = External.LogonUser(
    "john.doe", 
    "domain.com", 
    "MyPassword", 
    (int) AdvApi32Utility.LogonType.LOGON32_LOGON_INTERACTIVE, //2 
    (int) AdvApi32Utility.LogonProvider.LOGON32_PROVIDER_DEFAULT, //0 
    out userToken); 

if (!success) 
{ 
    throw new SecurityException("Logon user failed"); 
} 

using (WindowsIdentity.Impersonate(userToken)) 
{ 
    // do the stuff with john.doe's credentials 
}

有什么办法没有密码这样做呢?我有权访问它,因为我在模仿之前就开始创作,只是想我会问。 – Doug

我想应该调用'CloseHandle'(正如[LogonUser'文档中所述](https://msdn.microsoft.com/en-us/library/windows/desktop/aa378184(v = vs.85) .aspx))为使用块之后的'userToken'。或者这是由'WindowsIdentity'以某种方式调用的? – CodeFox

嗨如果这是ASP.NET应用程序,这是什么范围? 我应该在每一页中调用这个函数吗? –

您需要P /调用LogonUser() API。接受用户名,域名和密码并返回一个令牌。

它正是你必须使用的accesstoken。要得到它,你需要调用LogonUser方法:

oops没有意识到,我只是在这里的VB.net代码。

Private Declare Auto Function LogonUser Lib "advapi32.dll" (ByVal lpszUsername As [String], _ 
ByVal lpszDomain As [String], ByVal lpszPassword As [String], _ 
ByVal dwLogonType As Integer, ByVal dwLogonProvider As Integer, _ 
ByRef phToken As IntPtr) As Boolean 

和执行:

_Token = New IntPtr(0) 

Const LOGON32_PROVIDER_DEFAULT As Integer = 0 
'This parameter causes LogonUser to create a primary token. 
Const LOGON32_LOGON_INTERACTIVE As Integer = 2 
Const LOGON32_LOGON_NEWCREDENTIALS As Integer = 9 

_Token = IntPtr.Zero 

' Call LogonUser to obtain a handle to an access token. 
Dim returnValue As Boolean = LogonUser(_User, _Domain, _Password, LOGON32_LOGON_NEWCREDENTIALS, LOGON32_PROVIDER_DEFAULT, _Token) 

If False = returnValue Then 
    Dim ret As Integer = Marshal.GetLastWin32Error() 
    Console.WriteLine("LogonUser failed with error code : {0}", ret) 
    Throw New System.ComponentModel.Win32Exception(ret) 
End If 

_Identity = New WindowsIdentity(_Token) 
_Context = _Identity.Impersonate()
