Copy files over a network share

[John Varouxis]

Hi all,

I want to copy files residing in a network shared folder, but I have to pass
different user credentials than the executing user. How can I accomplish
this. The System.IO.File.Copy overloaded methods don't accept credentials in
any form.

Thanx in advance,
Yannis

Hi,
I think you'll have to use native API to accomplish this. You have to call
LogonUser API and then impersonate. There is a sample in MSDN, check
WindowsIdentity.Impersonate Method in System.Security.Principal namespace.

I have once used WNetUseConnection API to map drive with different
credentials and then access it (as an alternative method).

The simplest is to establish a network session with the share (using net use
....) from your logon session, no special code needed. This works only if
your applications runs in the same logon session of course.
