🧶 FunctionalStringExtensions

FunctionalStringExtensions is a C# class library that provides a set of extension methods for working with strings. These extensions are designed to make common string manipulation tasks more convenient and expressive. Whether you're dealing with default values, asynchronous operations, or executing actions based on string conditions, these extensions aim to simplify your code and enhance its readability.

Installation 🚀

To easily integrate the FunctionalStringExtensions library into your project, you can use NuGet Package Manager. NuGet is a package manager for .NET that simplifies the process of adding, removing, and updating libraries in your applications.

After that import the FunctionalStringExtensions namespace in your code files where you want to use the provided extension methods:

using FunctionalStringExtensions;

Available Extension Methods 🛠️

OrDefault

This extension method returns the provided default value if the input string is null or empty.

Usage:

string result = input.OrDefault("default value");

OrDefaultAsync

Similar to the OrDefault method, this asynchronous extension returns a default value obtained from a Task<string> if the input string is null or empty.

Usage:

string result = await input.OrDefaultAsync(Task.FromResult("default value"));

WhenNullOrEmpty

This extension method returns the result of the provided delegate function if the input string is null or empty.

Usage:

string result = input.WhenNullOrEmpty(() => "default value");

WhenNullOrEmptyAsync

Similar to the WhenNullOrEmpty method, this asynchronous extension returns a value obtained from a Task<string> returned by the delegate function if the input string is null or empty.

Usage:

string result = await input.WhenNullOrEmptyAsync(async () => await GetDefaultValueAsync());

OnNullOrEmpty

This extension method executes the provided action if the input string is null or empty.

Usage:

input.OnNullOrEmpty(() => Console.WriteLine("Input is null or empty."));

OnNullOrEmptyAsync

Similar to the OnNullOrEmpty method, this asynchronous extension executes a provided task if the input string is null or empty.

Usage:

await input.OnNullOrEmptyAsync(async () => await PerformAsyncAction());

ToSlug

Turns your string in a slug

Usage

var slug = "ICH MUß EINIGE CRÈME BRÛLÉE HABEN".ToSlug();

ToEnum

Parse your string to a Enum value

Usage

public enum FakeEnum
{
    Value1,
    Value2
}

var result = "Value1".ToEnum<FakeEnum>(); // FakeEnum.Value1

OnlyLetters

Search for letters (A to Z) in the string

Usage

var result = "abc123def456ghi".OnlyLetters(); //"abcdefghi"

OnlyNumbers

Search for numbers (0 to 9) in the string

Usage

var result = "abc123def456ghi".OnlyNumbers(); //"123456"

OnlyCharactersAndNumbers

Search for characters and numbers (A to Z or 0 to 9) in the string

Usage

var result = "12.8/0';@#!%^&*()a12,9abc".OnlyCharactersAndNumbers(); //"1280a129abc"

OnlySpecialCharacters

Search for especial characters (not A to Z and not 0 to 9) in the string

Usage

var result = "12.8/0';@#!%^&*()a12,9abc".OnlySpecialCharacters(); //"./';@#!%^&*(),"
