Easy.Tools.StringHelpers

Easy.Tools.StringHelpers is a high-performance, secure, and enterprise-ready .NET library providing a rich set of string extension methods. It is re-engineered with Zero-Allocation techniques for modern .NET, ReDoS protection for Regex operations, and strictly typed validation helpers.

Key Features

  • ** High Performance & Zero-Allocation:** Utilizes Span<T>, string.Create, and ValueTuple on modern frameworks (.NET 6+) to minimize memory pressure.
  • ** Security First:** - All internal Regex operations use Timeouts to prevent ReDoS (Regular Expression Denial of Service).
    • Random string/password generation uses CSPRNG (Cryptographically Secure Pseudo-Random Number Generator).
  • ** Enterprise Validation:** Built-in validators for Credit Cards (Luhn Algorithm), JSON, XML, URLs, Emails (RFC-compliant regex), and more.
  • ** Multi-Framework Support:** Runs everywhere. Supports .NET 10, .NET 9, .NET 8, .NET 6, .NET Standard 2.0/2.1, and .NET Framework 4.7.2+.

Installation

Install via NuGet Package Manager:

Install-Package Easy.Tools.StringHelpers

Or via .NET CLI:

dotnet add package Easy.Tools.StringHelpers

Usage Examples

1. Secure Validation

Validate inputs without throwing unnecessary exceptions.

using Easy.Tools.StringHelpers.Extensions;

// Email & Password Validation
if (userInput.IsValidEmail() && password.IsValidPassword(minLength: 10, requireSpecialChar: true))
{
    // Proceed safely...
}

// Credit Card Validation (Luhn Algorithm - Zero Allocation)
if (creditCardString.IsValidCreditCard()) 
{
    // Payment logic...
}

// JSON Structure Check
bool isJson = apiResponse.IsValidJson();

2. High-Performance Manipulation

Perform string operations with minimal memory footprint.

string title = "  High Performance Code  ";
// Slug generation (Supports Turkish characters: ı->i, ğ->g)
string slug = title.GenerateSlug(); // "high-performance-code"

string description = "This is a very long text that needs to be shortened.";
// Truncate using Span<T> optimizations
string preview = description.Truncate(20, addEllipsis: true); // "This is a very lo..."

3. PII Masking & Security

Securely handle sensitive data.

string email = "admin@example.com";
Console.WriteLine(email.MaskEmail()); // "ad***@example.com"

// Secure Random Password (CSPRNG)
string secret = GenerationExtensions.RandomPassword(16);

Extension Categories

Category Description
ValidationExtensions Validate Email, Credit Card (Luhn), JSON, XML, URL, IP, Palindrome, etc.

TruncateExtensions Smart string truncation with ellipsis support (Zero-alloc).
ManipulationExtensions General manipulation: RemoveWhitespace, SplitLines, Repeat, NormalizeSpaces.
MaskingExtensions Mask sensitive data like Emails or IDs.
SearchExtensions ContainsAny, ContainsAll, CountOccurrences, IsNumeric.
TransformationExtensions GenerateSlug (Turkish support), ToInitials, Reverse.
FormatExtensions ToSnakeCase, ToKebabCase, RemoveDiacritics.
GenerationExtensions Secure Random String & Password generation.
ConversionExtensions Safe type conversions (ToIntOrNull, To<T>).
CasingExtensions ToTitleCase, ToInvariantLower, ToInvariantUpper.
PaddingExtensions PadLeftWith, PadRightWith, PadBothWith (Center alignment).
LengthExtensions Fluent length checks: LongerThan, ShorterThan, IsLengthBetween.
RegexExtensions Safe Regex matching and extraction with Timeouts.
DateParsingExtensions Detect if string contains a valid date.
