我的目标是用 c# 将文件夹从我的系统复制到远程计算机。我到处搜索,找到了一些关于如何做到这一点的信息。我正在使用域、用户名和密码调用 LogonUser 函数,但它失败并返回 0。
下面是我的一段代码。你能帮我找出问题所在吗?
class Program
{
#region Assembly Functions

public static extern bool LogonUser(string lpszUsername, string lpszDomain, string lpszPassword,
int dwLogonType, int dwLogonProvider, out SafeTokenHandle phToken);
[DllImport("kernel32.dll")]
public static extern bool CloseHandle(IntPtr handle);
#endregion
static void Main(string[] args)
{
SafeTokenHandle safeTokenHandle;
WindowsImpersonationContext impersonatedUser = null;
WindowsIdentity newId;
IntPtr tokenHandle;
IntPtr userHandle = IntPtr.Zero;
tokenHandle = IntPtr.Zero;
Console.WriteLine("Enter your domain.");
string domain = Console.ReadLine();
Console.WriteLine("Enter you user name.");
string uname = Console.ReadLine();
Console.WriteLine("Enter your password (Caution, password won't be hidden).");
string password = Console.ReadLine();
const int LOGON32_PROVIDER_DEFAULT = 0;
//This parameter causes LogonUser to create a primary token.
const int LOGON32_LOGON_INTERACTIVE = 2;
bool logon = LogonUser(uname, domain, password,
LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, out safeTokenHandle);
if (false == logon)
{
int ret = Marshal.GetLastWin32Error();
Console.WriteLine("LogonUser failed with error code : {0}", ret);
throw new System.ComponentModel.Win32Exception(ret);
}
if (logon)
{
newId = new WindowsIdentity(safeTokenHandle.DangerousGetHandle());
using (impersonatedUser = newId.Impersonate())
{
// Check the identity.
Console.WriteLine("After impersonation: "
+ WindowsIdentity.GetCurrent().Name);
}
File.Copy(@"c:\result.xml", @"C:\result.xml", true);
}
//Undo impersonation
if (impersonatedUser != null)
{
impersonatedUser.Undo();
}
if (tokenHandle != IntPtr.Zero)
{
CloseHandle(tokenHandle);
}
}
}
