If statement

[Sottyoru]

Hello, I have couple of question about if statement. When I create password verifying program, at least 8 characters long is if (password.Length < 8) valid = false; like this, right? Then, how can I make program that must contain at least one digit and one uppercase for the password. Then, I tried to create while (valid && i < 1) { if (!Char.IsLetter(custID[i])) valid = false; i++; } like this, but it's not working. Please tell me.

Look into String.IndexOfAny http://msdn.microsoft.com/en-us/library/11w09h50.aspx[^]

You should be able to figure something out from the following Password Strength Control Regular expressions can help but they're not a silver bullet.

You need to read his earlier post. It's homework.

hi . if(password.Length < 8) is extreme 7 character. at least 8 character is this :

if(7

but for second part of your question ... ! try to understand these codes and get some idea to mke your own .never copy and paste!(just a suggestion to improve your skills,ofcourse you are free to copy :) )

char[] Digits = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9' };
if (7 < password.Length)
foreach (char t in Digits)
if (password.Contains(t))
for (int h = 65; h < 90; h++)
if (password.Contains((char)h))
break;//do proper operation ... .

Ah, yes. missed that other post. :-O It's his own problem if he can't be bothered to *learn* and just copies stuff.

In C# System.Char has a number of methods including isDigit()and isLetter()
