How to generate random color?

Solution 1
If you want to use the standard console colors, you could mix the ConsoleColor Enumeration and Enum.GetNames() to get a random color. You'd then use Console.ForegroundColor and/or Console.BackgroundColor to change the color of the console.
// Store these as static variables; they will never be changing
String[] colorNames = ConsoleColor.GetNames(typeof(ConsoleColor));
int numColors = colorNames.Length;
// ...
Random rand = new Random(); // No need to create a new one for each iteration.
string[] x = new string[] { "", "", "" };
while(true) // This should probably be based on some condition, rather than 'true'
{
// Get random ConsoleColor string
string colorName = colorNames[rand.Next(numColors)];
// Get ConsoleColor from string name
ConsoleColor color = (ConsoleColor) Enum.Parse(typeof(ConsoleColor), colorName);
// Assuming you want to set the Foreground here, not the Background
Console.ForegroundColor = color;
Console.WriteLine((x[rand.Next(x.Length)]));
Thread.Sleep(100);
}
Solution 2
// Your array should be declared outside of the loop
string[] x = new string[] { "", "", "" };
Random random = new Random();
// Also you should NEVER have an endless loop ;)
while (true)
{
Console.ForegroundColor = Color.FromArgb(random.Next(255), random.Next(255), random.Next(255));
Console.WriteLine((x[random.Next(x.Length)]));
Thread.Sleep(100);
}

So I'm messing around in c#, and was wondering how to generate my string from an array, but with a random color:
while (true) { string[] x = new string[] { "", "", "" }; Random name = new Random(); Console.WriteLine((x[name.Next(3)])); Thread.Sleep(100); }
When I'm outputting x, I want it to be a random color. Thanks
