visual studio - Running PowerShell commands from C# -

i have powershell script connects exchange online , performs tasks creating shared mailboxes, calendars, adding licenses etc.

the thing when run commands c# class error.

this connection:

 string schemauri = "http://schemas.microsoft.com/powershell/microsoft.exchange";         uri connectto = new uri("https://outlook.office365.com/powershell-liveid/");          var securepassword = new securestring();          foreach (char c in password)         {             securepassword.appendchar(c);         }          this.credential = new pscredential(login, securepassword);         wsmanconnectioninfo connectioninfo = new wsmanconnectioninfo(connectto, schemauri, credential);         connectioninfo.maximumconnectionredirectioncount = 5;         connectioninfo.authenticationmechanism = authenticationmechanism.basic;               this.remoterunspace = runspacefactory.createrunspace(connectioninfo);             this.remoterunspace.open(); 

this powershell working fine:

  powershell powershell = powershell.create();                 powershell.runspace = this.remoterunspace;                 pscommand command = new pscommand();                  command.addcommand("new-mailbox");                 command.addparameter("name", mailboxname);                 command.addparameter("shared");                 command.addparameter("primarysmtpaddress", formatedmailboxname);                 powershell.commands = command;                  powershell.invoke(); 

and code not working fine:

 powershell powershell = powershell.create();                 powershell.runspace = this.remoterunspace;                 pscommand command = new pscommand();                 command.addcommand("connect-msolservice");                 command.addcommand("import-module msonline");                 command.addparameter("credential", this.credential);                 command.addcommand("set-msoluser");                 command.addparameter("userprincipalname", userlogin);                 command.addparameter("usagelocation", "se"); 

the error got following:

additional information: term 'import-module msonline' not recognized name of cmdlet, function, script file, or operable program. check spelling of name, or if path included, verify path correct , try again.

i tried various things copy-paste dll's , changing active solution platform cpu 64 bit , none of helped me.

might stupid have tried following?

command.addcommand("import-module 'msonline'"); 

i have had similar issue skypeforbusiness module. worked when added ''.

can execute import-module msonline command in powershell ise?
