c# - start processes with a delay -

how can start 5 different processes, each own delay without holding other ones while waiting delay finish? can not use async or await

 foreach(string process1 in _processlist)   {      // random delay      process.start(process1);     } 

you start every process different thread.

foreach (string process1 in _processlist) {   thread t = new thread(() =>             {                thread.sleep(/*random number*/ 5);                process.start(process1);            });   t.start(); } 

that way each process have random timer before start , no process delayed start of other process.

if starting thread totaly impossible in situation, suggest wrapping process .bat , in batch file add sleep delay way process called in time , sleep delay respected.
