c# - Real-Time Text Processing -

i have program, translates text language. want improve small feature: text translates in real time when user types it.

i have written code:

private void textbox_keyup_1(object sender, system.windows.input.keyeventargs e) {    translatebox.text = translate.translatetext(texttotranslate.text, "eng", "es"); } 

it works, while type "hello world", function called 11 times. it's big load. is there way set timeout function?

ps. know how in js, not in c#...

you can consider actual translation when found "word" finished, such after space/tab/enter key typed, or when textbox losts focus etc.

private void textbox_keyup_1(object sender, system.windows.input.keyeventargs e) {    if(...) // here fill in condition       translatebox.text = translate.translatetext(texttotranslate.text, "eng", "es"); }
