An out parameter is used to pass a value out of a method.
It is not necessary to give the variable used as an out parameter an initial value.
An out parameter is always considered unassigned.
The method must assign the parameter a value prior to the method's termination.
using System;
class MainClass
{
public static void Add(int x,int y, out int ans)
{
ans = x + y;
}
public static void Main()
{
Console.WriteLine("Adding 2 ints using out keyword");
int ans;
Add(90, 90, out ans);
Console.WriteLine("90 + 90 = {0}\n", ans);
}
}
Adding 2 ints using out keyword
90 + 90 = 180
