Method overloading with ref and out

In this chapter you will learn:

  1. ref and out modifiers and method overloading
  2. ref and out cannot coexist

ref and out modifiers and method overloading

ref and out modifiers are part of the method signature.

class Math//j av a  2  s.c  o m
{
    int add(int i, int j)
    {
        return i + j;
    }
    int add(ref int i, ref int j){
        return i + j;
   }
}

ref and out cannot coexist

The following code shows that ref and out cannot coexist.

class Math//from  jav a  2  s . c o m
{
    int add(out int i, out int j)
    {
        return i + j;
    }
    int add(ref int i, ref int j){
        return i + j;
   }
}
