c# - How to check if process is still running before calling Process.GetProcessById? -

in .net process.getprocessbyid throws exception if process id not running. how safely phone call method won't throw exception? thinking like

if(process.isrunning(id)) homecoming process.getprocessbyid(id); else homecoming null; //or else

but can't find method check id, other getting running processes , check whether id exist in list.

public process getprocbyid(int id) { process[] processlist = process.getprocesses(); homecoming processlist.firstordefault(pr => pr.id == id); }

i looked within process.getprocessbyid method.

it uses internal static class processmanager ensure, process runs. processmanager gets processes running in scheme , checks there ids, think best way it.

so should consider overhead of exception or overhead of process array.

c# .net system.diagnostics
