Demystifying the C# Yield-Return Mechanism: Listing 1.
Generating a 10-string sequence with yield-return.
static IEnumerable<string> ComputeNextString(int n)
{
Random r = new Random(0);
char[] charArray =
new char[] { 'a','b','c','d','e','f','g','h' };
for (int i = 0; i < n; ++i)
{
int x = r.Next(0, charArray.Length);
int y = r.Next(0, charArray.Length);
char tmp = charArray[x];
charArray[x] = charArray[y];
charArray[y] = tmp;
yield return new String(charArray);
}
