Nullable Int32 Parse

is possible parse string nullable integer? if string can parsed parse method return integer, if not return null.

here how expect work:
string s = "5";
int32? i;
i = {something}.parse(s);

i have seen question asked many times, not find answer guessing cannot done in v2.

you can write own {something}, need contain method:

public static int? parse(string s) {     int i;     if (int.tryparse(s, out i)) return i;     else return null; }
