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><要运行的程序路径>为实际的值。
