In C#/.NET is possible to generate random index or item in few ways.

1. Random index example

string[] items = {
	"Dog",
	"Cat",
	"Cow",
	"Pig"
};

Random random = new Random();
int index = random.Next(items.Length);
Console.WriteLine(index);

Output:

2

2. Random item example

string[] items = {
	"Dog",
	"Cat",
	"Cow",
	"Pig"
};

Random random = new Random();
int index = random.Next(items.Length);
string item = items[index];
Console.WriteLine(index + ": " + item);

Output:

1 : Cat
