how to establish and enter an implicit remote session using runspace in powershell

Hi,

I am trying to establish an implicit session with a remote host from my machine from a C# code. I am using runspace API for that. the code snippet is provided below

Runspace runspace = RunspaceFactory.CreateRunspace();
                runspace.Open();

                //constructing the vmname parameter here
                vmname = useralias + DateTime.Now.ToString();

                Pipeline pipeline = runspace.CreatePipeline();
                string scripttext = "$secpasswd = ConvertTo-SecureString '222_bbbb' -AsPlainText –Force";
                string scripttext1 = "$mycreds = New-object -typename System.Management.Automation.PSCredential('TS-TEST-09\\Administrator',$secpasswd)";
                string scripttext2 = "$s = New-PSSession -ComputerName TS-TEST-09 -Credential $mycreds";
                //not accepting session string here, only computername acceptable
                string scripttext3 = "Enter-PSSession -Session $s";

                //put invoke command here instead of directly calling out the file execution
                //Command cmd = new Command(@"C:\mypath\helper.ps1", true);
                //cmd.Parameters.Add("local_useralias", useralias);
                //cmd.Parameters.Add("local_vmname", vmname);
                //cmd.Parameters.Add("local_datastore", datastoredropdown.Text.ToString());
                //cmd.Parameters.Add("local_architecture", architecturedropdown.Text.ToString());

                pipeline.Commands.AddScript(scripttext);
                pipeline.Commands.AddScript(scripttext1);
                pipeline.Commands.AddScript(scripttext2);
                pipeline.Commands.AddScript(scripttext3);
                //pipeline.Commands.Add(cmd);

                Collection<PSObject> results = pipeline.Invoke();


                runspace.Close();

this code is expected to enter into an implicit session with machine TS-TEST-09 and invoke the script helper.ps1 existing on that machine(that part is commented out in the code currently).

now the problem is that i can't enter into the session $s using -Session parameter(highlighted) however i can enter into it using -Computername parameter.

In later case, however, the code tries to access helper.ps1 from the local host and not on the remote server.

Is there a method to accomplish this task?

any help will be much appreciated.

Thanks,

Manish
