c#.net function -

namespace csfunction {     class program     {         static void main(string[] args)         {             public int addnumbers(int number1, int number2)             {                 int result = addnumbers(10, 5);                 console.writeline(result);                 }         }     }  } 

is code...am getting error like.....error type or namespace definition, or end-of-file expected
..hw can on come error

you defining method inside method, , not allowed in c#.

change this:

namespace csfunction {     class program     {         static void main(string[] args)         {         }          public static int addnumbers(int number1, int number2)         {            int result = addnumbers(10, 5);            console.writeline(result);         }     }  } 

then if want call addnumbers main, add following line inside main

addnumbers( 10, 5); 

also note not using parameters inside addnumbers anything. method should this:

public int addnumbers(int number1, int number2) {   int result = number1 + number2;   console.writeline(result); } 

in it's current form it's calling recursively also, , go endless loop.

so basically, there tons of problems code. should try entry level book on c# brush on c# skills.
