在C#中使用CreateProcessAsUser函数可以创建一个新的进程,并以指定用户的身份运行该进程。下面是一个示例代码:

using System;using System.Diagnostics;using System.Runtime.InteropServices;class Program{static void Main(string[] args){IntPtr userToken = IntPtr.Zero;IntPtr primaryToken = IntPtr.Zero;try{// 获取当前用户的访问令牌bool success = LogonUser("<用户名>", "<域>", "<密码>", 2, 0, ref userToken);if (!success){throw new System.ComponentModel.Win32Exception();}// 创建一个与用户访问令牌相关联的主访问令牌success = DuplicateToken(userToken, 2, ref primaryToken);if (!success){throw new System.ComponentModel.Win32Exception();}// 设置启动信息STARTUPINFO startupInfo = new STARTUPINFO();startupInfo.cb = Marshal.SizeOf(startupInfo);// 启动新进程的信息PROCESS_INFORMATION processInfo = new PROCESS_INFORMATION();// 创建新进程success = CreateProcessAsUser(primaryToken, "<要运行的程序路径>", null, IntPtr.Zero, IntPtr.Zero, false,0, IntPtr.Zero, null, ref startupInfo, out processInfo);if (!success){throw new System.ComponentModel.Win32Exception();}Console.WriteLine("新进程已启动,进程ID为: " + processInfo.dwProcessId);}finally{// 关闭句柄if (userToken != IntPtr.Zero){CloseHandle(userToken);}if (primaryToken != IntPtr.Zero){CloseHandle(primaryToken);}}}// 导入Windows API[DllImport("advapi32.dll", SetLastError = true, CharSet = CharSet.Unicode)]public static extern bool LogonUser(String lpszUsername, String lpszDomain, String lpszPassword,int dwLogonType, int dwLogonProvider, ref IntPtr phToken);[DllImport("advapi32.dll", SetLastError = true)]public static extern bool DuplicateToken(IntPtr ExistingTokenHandle, int SECURITY_IMPERSONATION_LEVEL,ref IntPtr DuplicateTokenHandle);[DllImport("kernel32.dll", SetLastError = true)]public static extern bool CloseHandle(IntPtr handle);[DllImport("advapi32.dll", SetLastError = true, CharSet = CharSet.Auto)]public static extern bool CreateProcessAsUser(IntPtr hToken, string lpApplicationName, string lpCommandLine,IntPtr lpProcessAttributes, IntPtr lpThreadAttributes, bool bInheritHandles, uint dwCreationFlags,IntPtr lpEnvironment, string lpCurrentDirectory, ref STARTUPINFO lpStartupInfo,out PROCESS_INFORMATION lpProcessInformation);[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]public struct STARTUPINFO{public int cb;public String lpReserved;public String lpDesktop;public String lpTitle;public uint dwX;public uint dwY;public uint dwXSize;public uint dwYSize;public uint dwXCountChars;public uint dwYCountChars;public uint dwFillAttribute;public uint dwFlags;public short wShowWindow;public short cbReserved2;public IntPtr lpReserved2;public IntPtr hStdInput;public IntPtr hStdOutput;public IntPtr hStdError;}[StructLayout(LayoutKind.Sequential)]public struct PROCESS_INFORMATION{public IntPtr hProcess;public IntPtr hThread;public uint dwProcessId;public uint dwThreadId;}}

注意替换代码中的<用户名>、<域>、<密码>和<要运行的程序路径>为实际的值。
