Question

我想从同一域中的远程计算机复制文件。所以我正在冒充这样做。

我正在使用advapi32.dll的DLLImport并正确模拟用户。

现在，当执行以下代码行时，我收到以下错误。

\\line

File.Copy(@"\\sins00048178\D$\BNCustody\Swift\Received_from_SWIFT\Error_files\E03248681_error.out", @"C:\E03248681_error.out", true);


\\Error
"Logon failure: user not allowed to log on to this computer."

根据要求填写完整的代码

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

IntPtr userHandle = IntPtr.Zero;
bool loggedOn = LogonUser(userid, domain, pass, 9, 0, out userHandle);

 if (loggedOn)
 {
    WindowsImpersonationContext context = WindowsIdentity.Impersonate(userHandle);
           File.Copy(@"\\sins00048178\D$\BNCustody\Swift\Received_from_SWIFT\Error_files\E03248681_error.out", @"C:\E03248681_error.out", true);

    context.Undo();

 }

提前致谢....

我所模仿的代码类似，但与您的代码存在细微差别。这是从我小组的其他开发人员传下来的，我确信它是从网上某处复制/粘贴的。它确实有效，我们在Windows服务和表单中使用它。

//defined elsewhere
WindowsImpersonationContext impersonatedUser;
WindowsIdentity newId;
IntPtr tokenHandle;

//Impersonate
tokenHandle = IntPtr.Zero;
bool returnValue = LogonUser(userName, domainName, password, 2, 0, ref tokenHandle);
if (returnValue) {
    newId = new WindowsIdentity(tokenHandle);
    impersonatedUser = newId.Impersonate();
} else {
    //do some error handling
}

//Undo impersonation
if (impersonatedUser != null) {
    impersonatedUser.Undo();
}
if (tokenHandle != IntPtr.Zero) {
    CloseHandle(tokenHandle);
}
