需要使用Regex.IsMatch的帮助 [英] Need help using Regex.IsMatch

问题描述

我正在尝试比较在Windows窗体上的文本框中输入的字符串，因为文本更改了，表示密码强度的复选框将被选中还是取消选中.

它可以很好地处理文本长度并可以正确更新，但是在与密码进行比较以查看密码中是否包含特殊字符(例如&，#，$，_等)等时，它可以正常工作.使用Regex.IsMatch不能正确更新，这是我正在使用的代码的一部分.

请告诉我这看起来是否正确?

I am trying to compare a string that is entered into a textbox on windows form as the text changes the checkboxes that represent the password strength will either check or uncheck.

It works fine for the the text length and updates properly but when compared to see if the password contains special characters such as &,#,$,_ etc.etc. using Regex.IsMatch it does not properly update here is part of the code I''m using.

Please tell me if this looks right?

if (password.Length <= 3)
            {                
                if (Regex.IsMatch(password, @"/.[!,@,#,$,%,^,&,*,?,_,~,-,£,(,)]/", RegexOptions.ECMAScript))
                    {
                        Security = (SecurityLevel.Unsecure);
                        
                    }
                    else
                    {
                        Security = (SecurityLevel.None);
                    }
                }
