Spaces in Paths as Command Line Args (C#)

I have a windows service that calls an external "updater" .exe.  I pass 3 args to the updater.  The problem I'm having is that the second and third and are both paths that almost always contain whitespace characters.  The updater app is always comparing files in "C:\Program Files\...\MyDir\ with files on a network share .that we have yet to establish.  

The code is below, but the simple problem is that Void Main(args[]) sees "C:\Program" and "Files\...\MyDir\" as separate arguments because of the space in the path.  Is there a way to escape that space and pass these two arguments as complete paths?  Seems like this .NET world we're in should have devised a way around the old 8.3 naming conventions.
 
The code in my service:
 string Update_Path=@"C:\Projects\C#\MyUpdatedProject\"); (this will be a UNC in production)  
 string Current_Path= @"C:\Program Files\MyCurProject\");
if(true)
  UpdateMe("MyServiceName", Current_Path, Update_Path);

private void UpdateMe(string ServiceName, string CurPath, string UpdatePath)
        {          
         
            Process proc = new Process();

            string args = ServiceName + " " +  @CurPath + " " + @UpdatePath + "";
            proc.StartInfo.FileName = CurPath + WinServiceUpdater.exe";
            proc.StartInfo.Arguments = args;
            try
            {
                proc.Start();
            }
            catch (System.InvalidOperationException IOex)
            {
                Debug.WriteLine(IOex.Message);
            }

            catch (Exception ex)
            {
                Debug.WriteLine(ex.Message);
            }

        }


WinServiceUpdater.exe:


static void Main(string[] args)
        {
            if (args.Length == 0)
                return;
            string svcName = args[0];            //Name of service to update (will stop and start with this name)
            string curPath = args[1];               //Directory Path of Current install files
            string updatePath = args[2];         //Path Where Update files sit
            DirectoryInfo UpdateSource = new DirectoryInfo(updatePath);
            DirectoryInfo CurentFiles = new DirectoryInfo(curPath);
           
            string debugmessage = "";
           
            System.ServiceProcess.ServiceController target = new System.ServiceProcess.ServiceController(svcName);

            if(target.Status == System.ServiceProcess.ServiceControllerStatus.Running)
                target.Stop();
            while (target.Status != System.ServiceProcess.ServiceControllerStatus.Stopped)
            {
                target.Refresh();
            }
            Thread.Sleep(2000);

            foreach (FileInfo updateFile in UpdateSource.GetFiles("*.*"))
            {
                if (File.Exists(curPath + updateFile.Name))
                {
                    debugmessage += "<br/>About to Delete: " + curPath + updateFile.Name;
                    //File.Delete(curPath + "\\" + updateFile.Name);

                    debugmessage += "<br/>About to Copy From: " + updatePath + updateFile.Name + " TO: " + curPath + updateFile.Name;
                    //File.Copy(updatePath + "\\" + updateFile.Name, curPath + "\\" + updateFile.Name);
                 
                }
                else
                {
                    debugmessage += "<br/>Does Not Exist: " + curPath + updateFile.Name;
                }            
            }

            debugmessage += "<br/><br/><br/><br/>target.status = " + target.Status.ToString();
            EmailUtil.SendMessage(debugmessage);
            target.Start();
        }
