string - Getting character position in c# -

this question has reply here:

how particular character position string using c# 1 reply

i using next code position of "e"

string = "abcdefghijklm"; int position = 0; (int = 0; < a.length; i++) { if (a.substring(i, 1) == "e") { position = +1; break; } }

above code homecoming position = 5,

i new c# question is fast way without loop this,

single/first occurrence

by using indexof homecoming index of position.

using system; class programme { static void main() { // a. // input string. const string s = "abcdefghijklm"; // b. // test indexof. if (int = s.indexof("e") != -1) { console.write("string contains 'e' @ position of "+i); } console.readline(); } }

this output

"string contains 'e' @ position of 4".

for quick/better understanding:

you can larn more here or here

the indexof gets position of character (-1 returned otherwise)

multiple occurrences:

if char value appears multiple times throughout string, use:

var foundindexes = new list<int>(); (int = 0; < mystr.length; i++) if (mystr[i] == 'a') foundindexes.add(i);
