强密码正则表达式[重复]

我需要强密码验证正则表达式

Special Characters - Not Allowed
Spaces - Not Allowed
Numeric Character - At least one character
At least one Capital Letter 
Minimum and Maximum Length of field - 6 to 12 Characters
Repetitive Characters - Allowed only two repetitive characters

我的正则表达式是^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?!.*\s)(?=(?:(\w)(?!\1{2}))+).{6,12}$但它忽略特殊字符（在哪里添加？）

请帮忙！

听起来不像是特别适合正则表达式的任务，因为您想同时测试多个条件。 （您可以使用多个正则表达式，但是使用 LINQ 的普通 C# 是测试它的更好方法。）尝试以下函数：

public static bool IsStrongPassword(string password)
{
    // Minimum and Maximum Length of field - 6 to 12 Characters
    if (password.Length < 6 || password.Length > 12)
        return false;

    // Special Characters - Not Allowed
    // Spaces - Not Allowed
    if (!(password.All(c => char.IsLetter(c) || char.IsDigit(c))))  
        return false;

    // Numeric Character - At least one character
    if (!password.Any(c => char.IsDigit(c)))
        return false;

    // At least one Capital Letter
    if (!password.Any(c => char.IsUpper(c)))
        return false;

    // Repetitive Characters - Allowed only two repetitive characters
    var repeatCount = 0;
    var lastChar = '\0';
    foreach(var c in password)
    {
        if (c == lastChar)
            repeatCount++;
        else
            repeatCount = 0;
        if (repeatCount == 2)
            return false;
        lastChar = c;
    }

    return true;
}

确保导入System.Linq当然可以，然后您就可以出发了。
