c# - Uncomment code programmatically -

how can comment out comment programmatically? think of this:-

void releasea() {    //todo: } //string = "test"; releasea(); textbox1.text = a;

how can achieve , implement method releasea comment out //string = "test"; searched still can't find anything.

i think want this:

string = "";  if (condition)     = "test";  textbox1.text = a;

so example of checkbox , text box:

string text = "";  if (checkbox.checked)     text = inputtextbox.text;  resulttextbox.text = text;
