java - Reading values from user in C# -

this code works fine, if user enters numbers in separate lines i.e. 10 12 result : 22

however, when try input there error. 10 12

now, know console.readline() reads entire line, , space isn't int , error. however, when used code in c, there scanf function, specifying datatype expect user, run both cases. also, think java's scanner.nextint() have not allowed such troubles. there simple way ask c# read data separated spaces, or lines in same manner? reason why never used c# in coding competitions. don't understand how solve problem.

using system; using system.collections.generic; using system.linq; using system.text; using system.threading.tasks;  namespace test {  class program  {      static void main(string[] args)     {         int result=0,a, b;         = int.parse(console.readline());         b = int.parse(console.readline());         result = + b;         console.writeline("the result {0}", result);         console.readkey();     }  } } 

here example extract number(s) string regex

            string input = "there 4 numbers in string: 40, 30, , 10.";             // split on 1 or more non-digit characters.             string[] numbers = regex.split(input, @"\d+");             foreach (string value in numbers)             {                 if (!string.isnullorempty(value))                 {                     int = int.parse(value);                     console.writeline("number: {0}", i);                 }             }             console.readkey();
