C# copy file to another directory using other domain/username/password

In c# 2008, I'm trying to copy a file to a destination path (for example \newserver\destinationFolder), that can be in another domain or using a different username/password than the current user. How can I specify these new network credentials before doing the File.Copy(...) ?

Thank you!

MapDrive => Copy files as local user => UnmapDrive. Take a look here:

    protected int MapDrive(){
        NETRESOURCEA[] resources = new NETRESOURCEA[1];
        resources[0] = new NETRESOURCEA();
        resources[0].dwType = 1;
        int dwFlags = 1;
        resources[0].lpLocalName = _DriveLetter;
        resources[0].lpRemoteName = _Path;
        resources[0].lpProvider = null; 
        int ret = WNetAddConnection2A(resources, null, null, dwFlags);
        return ret;
    }

    protected int UnmapDrive()
    {
        int ret = WNetCancelConnection2A(_DriveLetter, 0, true);
        return ret;
    }

Good question but I dont think this is possible. I believe this type of file copy from one domain to another ( where there is not a trust set up) would be considered security hole.

Some options:

  1. Set up a trust between the domains and give rights to the current user
  2. You could try a Shell execute command and see if you can make this work through command line parameters. I was thinking "Net use" command.
