c# - Iterating through alphabet and get newly created strings back to their original Button Form -

after long search found winning strategy clean code on hangman game, explanation needed understand.

when game opens, wanted letter buttons disabled. created method that,

private void disableletters(); {   a.enabled = false;   b.enabled = false;          .          .          .   z.enabled = false; } 

effective not elegant. iterating through alphabet try , condense code seemed logical.

private void disableletters() {   char alphebetstart = char.parse("a");   char alphabetend = char.parse("z");    (i = alphabetstart; <= alphabetend; i++);   {     string allletters = i.tostring();   } } 

but challenge appeared starting because couldn't use these newly created strings button forms this,

i.tostring().enabled = false; 

for obvious reasons. strings needed understood original form.

the long search revealed solution, don't understand quite it's doing. magic was,

controls[allletters].enabled = false; 

the "controls" reveals cryptic, "gets collection of controls contained within control." code works planned, looks it's doing saying, "take new strings created thru z , understand them name of buttons."

if briefly explain code doing, i'd grateful.

your final code in no way related variables. while there variable a represents control, there entirely separate collection within form has of control objects within it. each of control object has name field, , 1 of them has string value of "a". can find object in collection name value of "a" enough. there happens variable called a references control (from point of view of computer) coincidence. if renamed variable (but didn't change name of control) "a1", you'd still need use "a" control using controls collection.
