Copy file on a network shared drive

Question

I have a network shared drive ("\serveur\folder") on which I would like to copy file. I can write on the drive with a specific user ("user"/"pass"). How can I access the shared drived with write privilege using C#?

Answer 1

Create a user with privileges to write to the network drive and use impersonation within the c# to use that user when accessing the drive.

Answer 2

Untested code, but it will be similiar to:

AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);

WindowsIdentity identity = new WindowsIdentity(username, password);

WindowsImpersonationContext context = identity.Impersonate();

try
{
    File.Copy(@"c:\temp\MyFile.txt", @"\\server\folder\Myfile.txt", true);
}
catch
{
    context.Undo();
}
