通過網絡複製文件（需要驗證）

是否有某種方法可以通過網絡以.Net方式在網絡上覆制文件，從而作爲本地（非網絡）用戶進行身份驗證？通過網絡複製文件（需要驗證）

net use是不是一個選項，我似乎無法得到LogonUser工作。

任何想法？

[編輯]下面是一些代碼：

public class UserImpersonator : IDisposable 
{ 
    private WindowsImpersonationContext _impersonationContext; 
    private IntPtr _userHandle = IntPtr.Zero; 

    [DllImport("advapi32.dll", SetLastError = true)] 
    private static extern bool LogonUser(
     string lpszUsername, 
     string lpszDomain, 
     string lpszPassword, 
     int dwLogonType, 
     int dwLogonProvider, 
     out IntPtr phToken 
     ); 

    [DllImport("kernel32.dll", SetLastError = true)] 
    private static extern bool CloseHandle(IntPtr hHandle); 

    public UserImpersonator(string username, string password) 
    { 
     LogonUser(username, "", password, (int)LogonType.LOGON32_LOGON_NETWORK, 
        (int)LogonProvider.LOGON32_PROVIDER_DEFAULT, out _userHandle); 
     _impersonationContext = WindowsIdentity.Impersonate(_userHandle); 
    } 

    public void Dispose() 
    { 
     CloseHandle(_userHandle); 
     _impersonationContext.Undo(); 
    } 

    private enum LogonType : int 
    { 
     LOGON32_LOGON_INTERACTIVE = 2, 
     LOGON32_LOGON_NETWORK = 3, 
     LOGON32_LOGON_BATCH = 4, 
     LOGON32_LOGON_SERVICE = 5, 
     LOGON32_LOGON_UNLOCK = 7, 
     LOGON32_LOGON_NETWORK_CLEARTEXT = 8, 
     LOGON32_LOGON_NEW_CREDENTIALS = 9, 
    } 

    private enum LogonProvider 
    { 
     LOGON32_PROVIDER_DEFAULT = 0, 
    } 
}

當我在using(new UserImpersonator(username, password))包裹File.Copy操作，我得到：
