Execute multiple exchange online cmdlets using C# , ASP.NET with only 1 runspace -

i working on asp.net webapplication can connect exchange online , run commandlets.

the following working codebehind single button, gets list of mailboxes in asp.net

protected void finalconnection_click(object sender, eventargs e)     {         string username = "";         string password = "";         securestring securestring = new securestring();          foreach (char pass in password) {             securestring.appendchar(pass);         }          pscredential pscred = new pscredential(username,securestring);         wsmanconnectioninfo connectioninfo = new wsmanconnectioninfo(new uri("https://ps.outlook.com/powershell"), "http://schemas.microsoft.com/powershell/microsoft.exchange", pscred);         connectioninfo.authenticationmechanism = authenticationmechanism.basic;         connectioninfo.maximumconnectionredirectioncount = 2;          using (runspace runspace = runspacefactory.createrunspace(connectioninfo))         {             runspace.open();             using (powershell powershell = powershell.create())             {                 powershell.runspace = runspace;                 //create command , add parameter                 powershell.addcommand("get-mailbox");                 //var script = "get-mailbox";                 //powershell.addscript(script);                 //powershell.addparameter("recipienttypedetails", "usermailbox");                 //invoke command , store results in psobject collection                 var results = powershell.invoke();                 //iterate through results , write displayname , primarysmtp                 //address each mailbox                 foreach (psobject result in results)                 {                     //console.writeline(string.format("name: {0}, primarysmtpaddress: {1}",                     //        result.properties["displayname"].value.tostring(),                     //        result.properties["primarysmtpaddress"].value.tostring()                     //        ));                      newpowershell.innerhtml += result.properties["name"].value;                  }             }             runspace.close();         }      } 

i want create different buttons "get-users" "get-msolusers", want keep 1 runspace because of throttling restrictions, max runspace = 3;

should open , close runspace every button ? not correct idea believe

can please suggest alternatives on this?

you can keep runspace open , create new pipeline (runspace.createpipeline) each time need run script. i'm not sure if it's threadsafe though. may need limit runspace 1 open pipeline @ time.
