Yield_Return

Overview

The Yield_Return project is a C# library that extends the functionality of IEnumerable<T> with custom extension methods. This project demonstrates how to create and use these methods, including implementations of common LINQ operations such as Where, First, Any, All, Count, and others using the yield return statement for deferred execution.

Features

• Print: Prints the elements of a collection to the console.
• MyCount: Returns the number of elements in a collection.
• MyWhere: Filters elements of a collection based on a predicate.
• MyFirst: Returns the first element in a collection that satisfies a specified condition.
• MyAny: Checks if any element in a collection satisfies a specified condition.
• MyAll: Checks if all elements in a collection satisfy a specified condition.
• MyCountOf: Returns the number of elements in a collection that satisfy a specified condition.
• MyLast: Returns the last element in a collection that satisfies a specified condition.

Getting Started

Prerequisites

• .NET SDK

Installation

Clone the repository:

git clone https://github.com/yourusername/Yield_Return.git
cd Yield_Return

Usage

Create a new C# project or open an existing one. Add a reference to the Yield_Return library.

Here is an example demonstrating how to use the custom extension methods:

using System;
using System.Collections.Generic;
using Yield_Return;

namespace Example
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] words = { "adsad", "sdasdsa", "qqqqe" };
            Console.WriteLine(words.MyCount());

            Console.WriteLine("----------------");

            int[] nums = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
            foreach (int num in nums.MyWhere(i => i % 2 == 0))
            {
                Console.WriteLine(num);
            }

            Console.WriteLine("----------------");

            Console.WriteLine(nums.MyFirst(i => i % 2 == 0));

            Console.WriteLine("----------------");

            Console.WriteLine(nums.MyCountOf(i => i % 2 == 0));

            Console.WriteLine("----------------");

            Console.WriteLine(nums.MyLast(i => i % 2 == 0));
        }
    }
}

Methods

Print<T>(this IEnumerable<T> collection)

Prints the elements of the collection to the console.

public static void Print<T>(this IEnumerable<T> collection)

MyCount<T>(this IEnumerable<T> collection)

Returns the number of elements in the collection.

public static int MyCount<T>(this IEnumerable<T> collection)

MyWhere<T>(this IEnumerable<T> collection, Func<T, bool> func)

Filters elements of the collection based on a predicate.

public static IEnumerable<T> MyWhere<T>(this IEnumerable<T> collection, Func<T, bool> func)

MyFirst<T>(this IEnumerable<T> collection, Func<T, bool> func)

Returns the first element in the collection that satisfies a specified condition.

public static T MyFirst<T>(this IEnumerable<T> collection, Func<T, bool> func)

MyAny<T>(this IEnumerable<T> collection, Func<T, bool> func)

Checks if any element in the collection satisfies a specified condition.

public static bool MyAny<T>(this IEnumerable<T> collection, Func<T, bool> func)

MyAll<T>(this IEnumerable<T> collection, Func<T, bool> func)

Checks if all elements in the collection satisfy a specified condition.
