强密码正则表达式

我需要一个正则表达式,它至少包含以下五个字符类中的两个:
- 小写字符
- 大写字符 数字
- 标点符号
- "特别"字符(例如
@#$%^&*()_+|~-='
{}[]:";'& lt;>/等等)。
这是我到目前为止所做的
int upperCount = 0;
int lowerCount = 0;
int digitCount = 0;
int symbolCount = 0;
for (int i = 0; i < password.Length; i++)
{
if (Char.IsUpper(password[i]))
upperCount++;
else if (Char.IsLetter(password[i]))
lowerCount++;
else if (Char.IsDigit(password[i]))
digitCount++;
else if (Char.IsSymbol(password[i]))
symbolCount++;
但Char。IsSymbol在@ % &上返回false;美元。? 等
和通过regex
Regex Expression = new Regex("({(?=.*[a-z])(?=.*[A-Z]).{8,}}|{(?=.*[A-Z])(?!.*''s).{8,}})");
bool test= Expression.IsMatch(txtBoxPass.Text);
但是我需要一个带有"OR"条件的正则表达式。
换句话说,您想要的密码不只是包含一个"类"字符。然后可以使用
^(?![a-z]*$)(?![A-Z]*$)(?!'d*$)(?!'p{P}*$)(?![^a-zA-Z'd'p{P}]*$).{6,}$
解释:
^ # Start of string
(?![a-z]*$) # Assert that it doesn't just contain lowercase alphas
(?![A-Z]*$) # Assert that it doesn't just contain uppercase alphas
(?!'d*$) # Assert that it doesn't just contain digits
(?!'p{P}*$) # Assert that it doesn't just contain punctuation
(?![^a-zA-Z'd'p{P}]*$) # or the inverse of the above
.{6,} # Match at least six characters
$ # End of string
