HeroKit

The HeroKit library, providing utility operations, offers a comprehensive set of extension methods for controlling, converting, and manipulating various data types. Designed for projects developed in C#, this extensive library enables performing diverse operations on different data types, ranging from arrays to date-time values, objects, and strings.

Installation & Usage

The HeroKit library contains extension methods to provide helpful functionalities in C# projects. Below, you can find examples of how to use this library:

1. Add the HeroKit library to your project:
   • Open NuGet Package Manager Console to add the library to your project via NuGet Package Manager.
   • Enter the following command to add the HeroKit library to your project:

     Install-Package HeroKit
     

2. Don’t forget to include the relevant namespace statements before using extension methods:
   • For instance, if you’re working with arrays, add the namespace of the relevant class at the beginning of your project (using HeroKit.Arrays;).
3. Perform operations using extension methods:
   • You can use classes like ArrayControlExtensions, ArrayConversionExtensions, ArrayManipulationExtensions for array-related operations.
   • For date and time formatting, you can utilize methods from the DateTimeFormattingExtensions class.
   • For object control and conversions, use ObjectControlExtensions and ObjectConversionExtensions classes.
   • String operations can be performed using StringControlExtensions, StringConversionExtensions, and StringManipulationExtensions classes.
   • For type control and conversions, you can use the TypeControlExtensions class.
