What will happen,when we compile below C# code? private void sum(int a,int b) { return a + b; }

It will give below compile-time error as:-
Since '_Default.sum()' returns void, a return keyword must not be followed by an object expression.
Means if the return type is void,then we need not return any value from code as void returns Nothing.

What will happen,when we compile below C# code? private int Calculate(int a, int b) { int i = a; int j = b; int k = i + j; }

'_Default.Calculate(int,int)': not all code paths return a value
Above error means if we have defined any method with return type then we have to explicitly return that type otherwise it will not compile and will throw above error.So we have to re-write below code as:-

private int Calculate(int a, int b)

{

  int i = a;

  int j = b;

  int k = i + j;

  return k;

}
