在Windows線程中類比其他使用者上下文！

在Windows線程中類比其他使用者上下文，需要使用WindowsIdentity.Impersonate方法！同時還需要用LogonUser API來擷取安全性權杖，代碼如下：

using System.Runtime.InteropServices;
using System.Security.Principal;
class Program
{
      [DllImport("Advapi32.dll")]
static extern bool LogonUser(
string sUserName,
string sDomain,
string sUserPassword,
uint dwLogonType,
uint dwLogonProvider,
out System.IntPtr token);

       [DllImport("Kernel32.dll")]
static extern void CloseHandle(System.IntPtr token);

static void Main()
       {
             System.IntPtr pToken;
if(LogonUser(
"Administrator",
"DomainName",
"Password",
                    2,
                    0,
out pToken)){
             WindowsIdentity.Imersonate(pToken);//類比使用者
             WindowsIdentity id=WindowsIdentity.GetCurrent();
             Console.WriteLine(id.Name);
             CloseHandle(pToken);
