How can I generate random alphanumeric strings?

Question

How can I generate a random 8 character alphanumeric string in C#?

Accepted Answer

I heard LINQ is the new black, so here's my attempt using LINQ:

```
private static Random random = new Random();

public static string RandomString(int length)
{
    const string chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
    return new string(Enumerable.Repeat(chars, length)
        .Select(s => s[random.Next(s.Length)]).ToArray());
}
```

(Note: The use of the `Random` class makes this unsuitable for anything security related, such as creating passwords or tokens. Use the `RNGCryptoServiceProvider` class if you need a strong random number generator.)
