c# - Trying to start a thread based on a users choice -


i have combobox many choices. user chooses takes them case statement. in case 1 of items gets choosen string. string want use take start specific function thread. e.g. have function 

    public void doworkap(){}

and another

    public void doworkag(){}

from combo box user makes choice , case statemtn have string called swhichwork , set either "doworkag" or "doworkap"

now in ui code have thread

    thread t = null;

and when button pressed function called , in function have

    t = new thread(swhichwork);       t.start();

this seemed woudl exect swhichwork substituted "doworkag" or "doworkap" instead get

"cannot convert 'string' system.threading.parameterizedthreadstart' "

now take out swhichworks , have following

    t = new thread(doworkag);        t.start();

this compiles , takes me correct place. question how can have variable string choosen combox case stament take me same place?

if have 2 options, i'd go for

t = new thread(swhichwork == "doworkag" ? doworkag : doworkap);

this work well:

t = new thread(this.gettype().getmethod(swhichwork).invoke(this, new object[]));
