UNLEIN® Utilities - C# Package

Overview

The UNLEIN® Utilities package is a comprehensive collection of ready-to-use methods designed to improve your C# applications. It simplifies tasks like generating hash values (both one-way and two-way), managing logging, handling file uploads, making API calls, and performing database operations. Whether you're building a simple app or a complex enterprise system, this package offers optimized, easy-to-use solutions.

  • One-way hash values.
  • Two-way hash values (with key for encryption/decryption).
  • Hash generation for email subscriptions and unsubscribe tokens.
• File Handling:
  • Get file details before upload.
  • Generate Base64 string data from file before upload.
  • Easy file upload with real-time renaming feature.
  • Upload base64 string files.
• String Manipulation:
  • SafeReplace method for precise find and replace operations.
  • Shuffle characters in a string.
  • Between String extension for extracting or removing substrings.
• Database Operations:
  • Fast database connections for quick data retrieval.
  • Query and query list methods for dynamic data binding.
  • Bulk insert and insert queries.
  • Support for complex data types and stored procedures.
• Logging:
  • Simple, lightweight logging functionality.
  • Auto logging for API calls.
  • Supports .NET platforms above version 6.0.
  • Manage log files with "Rolling Interval" functionality.
• API Calls:
  • Prebuilt methods for making GET, POST, PUT, PATCH, and DELETE requests.
  • Automatic API request logging.
• Cookie Manager:
  • Get, save, update, and delete cookies programmatically.
• Mathematical Operations:
  • Advanced statistical functions (Standard Deviation, Moving Averages)
  • Number theory operations (GCD, LCM, Prime checking)
  • Combinatorics calculations (Combinations, Binomial Coefficients)
  • Financial calculations (EMA, WMA)
  • Mathematical series (Fibonacci)
  • Root calculations and interpolation
• DateTime Extensions:
  • Business day calculations
  • Week and month boundary operations
  • Human-readable time ago strings
  • Date range operations
• Data Validation:

Usage

Mathematical Operations

using UNLEIN.Utilities;

// Statistical Analysis
var numbers = new[] { 1.0, 2.0, 3.0, 4.0, 5.0 };
double stdDev = numbers.StandardDeviation();
var movingAvgs = numbers.MovingAverage(3).ToList();
var ema = numbers.ExponentialMovingAverage(3).ToList();

// Number Theory
bool isPrime = 17L.IsPrime(); // true
long gcd = 48L.GCD(18L); // 6
long lcm = 12L.LCM(18L); // 36

// Advanced Calculations
double cubeRoot = 27.0.NthRoot(3); // 3.0
double interpolated = 0.0.Lerp(100.0, 0.5); // 50.0

// Combinatorics
long combinations = 5.Combinations(2); // 10
var fibSequence = 10.Fibonacci().ToList();

DateTime Operations

using UNLEIN.Utilities;

var date = DateTime.Now;
var weekStart = date.StartOfWeek();
var monthEnd = date.EndOfMonth();
var timeAgo = date.AddDays(-5).ToTimeAgo(); // "5 days ago"
var nextWorkday = date.NextBusinessDay();

Data Validation

using UNLEIN.Utilities;

"123-456-7890".IsValidPhoneNumber(); // true
"4532015112830366".IsValidCreditCard(); // true
"https://example.com".IsValidUrl(); // true
"192.168.1.1".IsValidIPv4(); // true
"Password123!".IsStrongPassword(); // true

Collection Operations

using UNLEIN.Utilities;

var numbers = Enumerable.Range(1, 10);

// Chunk large collections
var chunks = numbers.Chunk(3); // [[1,2,3], [4,5,6], [7,8,9], [10]]

// Get random element
var randomNumber = numbers.Random();

// Check uniqueness
var hasUnique = numbers.AllUnique(); // true

// Shuffle collection
var shuffled = numbers.Shuffle();

// Get slice of collection
var slice = numbers.Slice(2, 5); // [3,4,5]

// Group by frequency
var chars = "hello world".ToCharArray();
var frequency = chars.GroupByFrequency(c => c);

Logging

To start using the logging functionality, include the UNLEIN.Utilities.Log namespace and configure your logger:

using UNLEIN.Utilities.Log;

var logger = new LoggingConfig()
                .WriteFile("logs/log.txt", RollingInterval.Hour)
                .Start();

Log.Info("Hey");

//Api Callings
var get = await Api.GetAsync("todos/1");
var post = await Api.PostAsync("posts", data);
//You can also use PUT, PATCH, and DELETE requests in the same way.
//To enable API logging, configure the following
//Auto Logging for API
Api.ApiLog.IsApiLog = true;
Api.ApiLog.IncBaseUrl = true;
Api.ApiLog.IncRequest = true;
Api.ApiLog.FilePath = "logs/apilog.txt";
Api._BaseUrl = "https://example.com/";
