Example:
using System;
using System.Collections.Generic;
class ExampleYieldReturn
{
static void Main(string[] args)
{
//with every call it goes to where it left till it encounters yield return
foreach(int n in GetNumbers())
{
Console.WriteLine(n);
}
Console.ReadLine();
}
public static IEnumerable<int> GetNumbers()
{
Console.WriteLine("Print number 52");
yield return 52; // will go back to the caller ie foreach
Console.WriteLine("Print number 63");
yield return 63;// again will go back to the caller ie foreach
Console.WriteLine("Print number 72");
yield return 72;// again will go back to the caller ie foreach
}
}
Output:
Print number 52
52
Print number 63
