c# - Replace one word with different values -

i have string "{day} - victory day. {day} - birthday";

how replace {day} different numbers? try:

string text = "{day} - victory day. {day} - birthday"; if (text.contains("{day}"))     text = text.replace("{day}", xnet.rand.next(1, 30).tostring()); 

but day same in 2 replacements.

use regex.replace matchevaluator delegate:

string text = "{day} - victory day. {day} - birthday"; text = regex.replace(text, @"\{day\}", m => xnet.rand.next(1, 30).tostring());
