StringMate offers a collection of useful classes designed for working with the C# string type.

• StringValidation is a static class which contains all the validation methods.
• Since it is a Static class, garbage collection won't be an issue.
• To install, run dotnet add package StringMate or from Nuget

Example Usage:

using StringMate.Validators;
using StringMate.Helpers;


var resultOfTimeValidation = StringValidation.Is12HourTime("06:10 PM", includeSecond: false);
if (resultOfTimeValidation) Console.WriteLine("Yee! Validated time");


var constructedDateFormat = new DateFormatBuilder()
    .AddDayWithLeadingZero()
    .AddMonthWithLeadingZero()
    .AddYearWithFourDigit()
    .AddHyphenDelimiter()
    .Build();

var resultOfDateValidation = StringValidation.IsDate("10-11-2014", dateFormat: constructedDateFormat);
if (resultOfDateValidation) Console.WriteLine("Yee! Validated date");

Available Methods in StringValidation Class

Method	Signature	Description
IsDate	bool IsDate(string text, string dateFormat)	Validates date. Supports - or / as delimiter. Use the DateFormatBuilder helper class to construct the dateFormat parameter. IDateFormatBuilder interface is also included for loose coupling and dependency injection purpose.
Is12HourTime	bool Is12HourTime(string text, bool includeSecond)	Validates 12-hour time format.
Is24HourTime	bool Is24HourTime(string text, bool includeSecond)	Validates 24-hour time format.
IsStrongPassword	IsStrongPassword(string text, int minLength = 8, int minLowercase = 1, int minUppercase = 1, int minNumbers = 1, int minSymbols = 1, int minUniqueChars = 0)	Validates whether the input string represents a strong password. Default parameters are added for convenience.
IsHash	bool IsHash(string text, HashingAlgorithm algorithm)	Validates hash based on the specified hashing algorithm.HashingAlgorithm is an enum type.
IsSlug	bool IsSlug(string text)	Validates slug.
IsMongoId	bool IsMongoId(string text)	Validates MongoDB ObjectId.
IsUuid	bool IsUuid(string text, UuidVersion version)	Validates UUID based on the specified version. UuidVersion is an enum type.
IsJwt	bool IsJwt(string text)	Validates JSON Web Token (JWT).
IsBase64	bool IsBase64(string text, bool checkUrlSafety)	Validates Base64-encoded string, with URL safety check.
IsEnumMember	bool IsEnumMember<TEnum>(string text)	Validates enum member of the given enum generic type parameter.
IsHexadecimal	bool IsHexadecimal(string text)	Validates hexadecimal number.
