StringHelper

All methods are exposed as static members of the StringHelper class.

// Parses and converts a mobile phone number to a format like +77015543456 (strips everything except digits and +).
public static string ParseMobilePhone(string phone);

// Checks if an e-mail address is correct (validated via System.Net.Mail.MailAddress).
public static bool ValidateEMail(string eMail);

// Checks if a mobile phone number is correct (must match ^\+[1-9]{1}[0-9]{4,12}$).
public static bool ValidateMobilePhone(string phone);

// Indistinct (fuzzy) matching of two strings. Returns the similarity percentage (0..100)
// by comparing blocks of increasing length up to comparingBlockLength.
public static float IndistinctMatching(string stringA, string stringB, int comparingBlockLength = 3);

// Strips HTML tags from the source string.
public static string StripHtmlTags(string source);

Note: StripHtmlTags is a cosmetic tag remover (a simple <.*?> regex), not an HTML/XSS sanitizer. Do not rely on it to make untrusted input safe for rendering — it does not handle malformed tags, comments, scripts, or attributes.

Usage Example

var normalized = StringHelper.ParseMobilePhone("+7 (701) 554-34-56"); // "+77015543456"

if (!StringHelper.ValidateEMail(email))
    throw new ArgumentException("Invalid e-mail address");

var similarity = StringHelper.IndistinctMatching("Microsoft", "Mircosoft"); // high percentage
