亂碼產生程式
public string RandomString(int length)
{
Random r = new Random(Environment.TickCount);
string chars = "0123456789abcdefghijklmnopqrstuvwxyz";
StringBuilder builder = new StringBuilder(length);
for (int i = 0; i < length; ++i)
builder.Append(chars[r.Next(chars.Length)]);
return builder.ToString();
}
簡單的亂數產生，不過不是用於瞬間產生大量亂數:D
