How to Use

Examples

General

bool isValidAnagram1 = new Anagram().IsValid("new york times", "monkeys write"); bool isValidAnagram2 = new Anagram().IsValid("résumé", "mésuré"); bool isValidPalindrome1 = new Palindrome().IsValid("Taco cat"); bool isValidPalindrome2 = new Palindrome().IsValid("Was it Eliot's toilet I saw?"); // The PanGram class delivers exceptional performance. bool isValidPangram1 = new Pangram().IsValid("The quick brown fox jumps over the lazy dog"); bool isValidPangram2 = new Pangram().IsValid(new System.Text.StringBuilder().Append('x', 1_000_000).Append("abcdefghijklmnopqrstuvwxyz").ToString()));

Parentheses validator

IParenthesesValidator parenthesesValidator; bool isValid = _parenthesesValidator.IsValid("([{}])"); // Returns true isValid = _parenthesesValidator.IsValid("Something(yellow[{with a tail}])!"); // Returns true isValid = _parenthesesValidator.IsValid("("); // Returns false isValid = _parenthesesValidator.IsValid("[("); // Returns false isValid = _parenthesesValidator.IsValid("[()]"); // Returns true isValid = _parenthesesValidator.IsValid("([)]"); // Returns false (because not strictly nested) IParenthesesValidator customValidator = new ParenthesesValidator(new() { { '«', '»' }, { '{', '}' } }); isValid = customValidator.IsValid("«test»"); // Returns true isValid = customValidator.IsValid("(test)"); // Returns true (because these parentheses aren't included in the custom validator) isValid = customValidator.IsValid("(test)(("); // Returns true (because these parentheses aren't included in the custom validator) isValid = customValidator.IsValid("«t{e}st»"); // Returns true

Roman

IRomanNumeralConverter romanNumeralConverter = new RomanNumeralConverter(); // Supported range for IntToRoman(): Between 0 and int.MaxValue. romanNumeralConverter.IntToRoman(1); // Outputs I romanNumeralConverter.IntToRoman(10); // Outputs X romanNumeralConverter.IntToRoman(49); // Outputs XLIX romanNumeralConverter.IntToRoman(10000); // Using the default overline Roman large number format, outputs: X̅ romanNumeralConverter.IntToRoman(15000); // Using the default overline Roman large number format, outputs: X̅V̅ romanNumeralConverter.IntToRoman(10000, RomanLargeNumberFormat.Apostrophus); // Outputs: CC|Ↄ|Ↄ romanNumeralConverter.IntToRoman(15000, RomanLargeNumberFormat.Parentheses); // Outputs: (XV) romanNumeralConverter.IntToRoman(5000, RomanLargeNumberFormat.MPrefix); // Outputs: MMMMM romanNumeralConverter.IntToRoman(int.MaxValue, RomanLargeNumberFormat.Overline); // Outputs: I̅I̅C̅X̅L̅V̅I̅I̅C̅D̅L̅X̅X̅X̅I̅I̅I̅DCXLVII // Supported range for SmallRomanToInt(): Between 0 and 3999. romanNumeralConverter.SmallRomanToInt("mcmxcix"); // Outputs: 1999

Truncator

<span disabled>Truncator.TruncateWithEllipsis(@tag.Name, 5)</span> // If tag.Name = "Red cars" then it now becomes "Red..".
