I need to maintain a years worth of eventlogs on over 200 systems. Because of several environmental factors I've decied to add some functionallity to the monitor service we already have running on all the systems.

During my development, I am getting an "Access Denied" error with the attached code. I'm sure it's because I'm not assing credentials, but I can't find any examples of it in C#. Can anyone assist? I think I can convert from VB.net if anyone has an example of that?

Sorry, the error is coming from the InvokeMethod.
ConnectionOptions oConn = new ConnectionOptions();
            ManagementScope oMs = new ManagementScope(@"\\localhost", oConn);

            ObjectQuery oQry = new ObjectQuery("select * from Win32_NTEventLogFile");

            ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(oMs, oQry);

            ManagementObjectCollection oRtnColl = oSearcher.Get();

            foreach (ManagementObject oRtn in oRtnColl)
            {
                Console.Write("Name: " + oRtn["Name"].ToString() + "\t");
                Console.WriteLine("FileName: " + oRtn["LogfileName"].ToString());
                
                Object[] file = {@"C:\Test" + oRtn["Name"].ToString()};
                               
                oRtn.InvokeMethod("BackupEventlog", file);
                //Console.WriteLine("FreeSpace: " + oRtn["FreeSpace"].ToString());
                //Console.WriteLine("Size: " + oRtn["Size"].ToString());

            }
