获取已登录Windows用户的名字和姓氏可以通过以下步骤:
具体实现步骤如下:
Step 1: 获取访问令牌
使用Windows API函数OpenProcessToken来打开当前进程的访问令牌。然后使用GetTokenInformation函数获取令牌的用户信息。
Step 2: 获取安全标识符(SID)
使用GetTokenInformation函数获取令牌的用户信息,其中包括用户的安全标识符(SID)。
Step 3: 查询用户配置信息
使用Windows API函数LookupAccountSid来查询Windows注册表中的用户配置信息。该函数需要提供用户的安全标识符(SID)作为输入参数。
Step 4: 提取用户的名字和姓氏
从查询到的用户配置信息中提取用户的名字和姓氏。
以下是一个示例代码,使用C#语言实现上述步骤:
using System;
using System.Runtime.InteropServices;
using System.Security.Principal;
class Program
{
[DllImport("advapi32.dll", SetLastError = true)]
public static extern bool OpenProcessToken(IntPtr ProcessHandle, uint DesiredAccess, out IntPtr TokenHandle);
[DllImport("kernel32.dll")]
public static extern IntPtr GetCurrentProcess();
[DllImport("advapi32.dll", SetLastError = true)]
public static extern bool GetTokenInformation(IntPtr TokenHandle, TOKEN_INFORMATION_CLASS TokenInformationClass, IntPtr TokenInformation, uint TokenInformationLength, out uint ReturnLength);
[DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern bool LookupAccountSid(string lpSystemName, IntPtr Sid, System.Text.StringBuilder lpName, ref uint cchName, System.Text.StringBuilder ReferencedDomainName, ref uint cchReferencedDomainName, out SID_NAME_USE peUse);
public enum TOKEN_INFORMATION_CLASS
{
TokenUser = 1,

TokenImpersonationLevel,

MaxTokenInfoClass
}
public enum SID_NAME_USE
{
SidTypeUser = 1,
SidTypeGroup,
SidTypeDomain,
SidTypeAlias,
SidTypeWellKnownGroup,
SidTypeDeletedAccount,
SidTypeInvalid,
SidTypeUnknown,
SidTypeComputer
}
static void Main(string[] args)
{
IntPtr tokenHandle;
IntPtr processHandle = GetCurrentProcess();
OpenProcessToken(processHandle, 8, out tokenHandle);
uint tokenInfoLength = 0;
GetTokenInformation(tokenHandle, TOKEN_INFORMATION_CLASS.TokenUser, IntPtr.Zero, tokenInfoLength, out tokenInfoLength);
IntPtr tokenInformation = Marshal.AllocHGlobal((int)tokenInfoLength);
GetTokenInformation(tokenHandle, TOKEN_INFORMATION_CLASS.TokenUser, tokenInformation, tokenInfoLength, out tokenInfoLength);
TOKEN_USER tokenUser = (TOKEN_USER)Marshal.PtrToStructure(tokenInformation, typeof(TOKEN_USER));
IntPtr userSid = tokenUser.User.Sid;
uint nameLength = 0;
uint domainLength = 0;
SID_NAME_USE sidType;
LookupAccountSid(null, userSid, null, ref nameLength, null, ref domainLength, out sidType);
StringBuilder name = new StringBuilder((int)nameLength);
StringBuilder domain = new StringBuilder((int)domainLength);
LookupAccountSid(null, userSid, name, ref nameLength, domain, ref domainLength, out sidType);
Console.WriteLine("用户名: " + name);
Console.WriteLine("域名: " + domain);
Marshal.FreeHGlobal(tokenInformation);
}
}
[StructLayout(LayoutKind.Sequential)]
public struct SID_AND_ATTRIBUTES
{
public IntPtr Sid;
public uint Attributes;
}
[StructLayout(LayoutKind.Sequential)]
public struct TOKEN_USER
{
public SID_AND_ATTRIBUTES User;
}
这段代码将打印出当前登录用户的用户名和域名。
请注意,这只是一个示例代码,实际使用时可能需要进行错误处理和资源释放等操作。此外,该代码仅适用于Windows操作系统。
