I recently had to make a method that creates a random generated password in C#. So, I looked at the web for such a function and I found this one.
It was really simple and short and just what I was looking for. But, there is always a but, it didn't work. So I modified it a bit, and it now looks like this and it works.
private static string CreateRandomPassword(int passwordLength)
{
string allowedChars = "abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNOPQRSTUVWXYZ0123456789!@$?_-";
char[] chars = new char[passwordLength];
Random rd = new Random();
for (int i = 0; i < passwordLength; i++)
{
chars[i] = allowedChars[rd.Next(0, allowedChars.Length)];
}
return new string(chars);
}
It's that simple.
