C#亂數(隨機)產生英文單字

 亂數產生英文

private static String RandomString(int length)
{
    //少了英文的IO和數字10，要避免使用者判斷問題時會使用到
    string allChars = "ABCDEFGHJKLMNPQRSTUVWXYZ23456789";
    //string allChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";//26個英文字母
    char[] chars = new char[length];
    Random rd = new Random(Guid.NewGuid().GetHashCode());
    rd.Next();
    for (int i = 0; i < length; i++)
    {
        chars[i] = allChars[rd.Next(0, allChars.Length)];
    }

    return new string(chars);
}
