Network file copy in .NET

Question

I have an Ubuntu box running a Samba share open to everyone. I can access it via \ip address so I know I have full access to it.

From within my application I am trying the following but it will not work via the ip address only the DNS name.

// val = ip address
File.Copy("\\\\" + val + "\\share\\vSphere\\vSphere.exe", Temp + "vSphere.exe", true);

I need to use the IP Address as people who are VPN'ing in won't be able to have the program access the dns name only the ip address.

Solution

First, try by giving IP address as below

File.Copy(@"\\192.100.1.23\share\vSphere\vSphere.exe", Path.combine(Temp ,"vSphere.exe"), true);

if error exist try using impersonate, give user name and password

AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);

WindowsIdentity idnt = new WindowsIdentity(username, password);

WindowsImpersonationContext context = idnt.Impersonate();

File.Copy(@"\\192.100.1.23\share\vSphere\vSphere.exe", Path.combine(Temp ,"vSphere.exe"), true);

context.Undo();
