DevElf

Essential .NET utilities for argument validation and string handling that make day-to-day development simpler and safer.

This library is currently in development and is not ready for production use.

The API is subject to breaking changes without notice. Features may be incomplete or unstable. Use at your own risk in non-production environments only.

NuGet Version

Features

  • Argument validation extensions - Fluent validation methods that throw appropriate exceptions
  • Nullable string helpers - Readable extension methods for common string null/empty checks

Installation

dotnet add package DevElf

Quick Start

Argument Validation

using DevElf.ArgumentValidation;

void ProcessData(string name, int? id, DayOfWeek day)
{
    name.ThrowIfNullOrWhiteSpace();     // throws ArgumentException if null/empty/whitespace
    id.ThrowIfNull();                   // throws ArgumentNullException if null
    day.ThrowIfNotDefined();            // throws ArgumentException if undefined enum value

    // Safe to use validated parameters
}

String Extensions

using DevElf.Extensions;

string? input = GetUserInput();

if (input.IsNullOrWhiteSpace())
{
    Console.WriteLine("Please provide valid input");
    return;
}

// input is guaranteed to have content
ProcessInput(input);

API Reference

Argument Validation Extensions

Method Description
ThrowIfNull<T>(this T? value) Throws ArgumentNullException if value is null
ThrowIfNullOrEmpty(this string? value) Throws ArgumentException if string is null or empty
ThrowIfNullOrWhiteSpace(this string? value) Throws ArgumentException if string is null, empty, or whitespace
ThrowIfNotDefined<T>(this T value) where T : Enum Throws ArgumentException if enum value is not defined

String Extensions

Method Description
IsNull(this string? text) Returns true if string is null
IsNullOrEmpty(this string? text) Returns true if string is null or empty
IsNullOrWhiteSpace(this string? text) Returns true if string is null, empty, or whitespace

All string extension methods are annotated with [NotNullWhen(false)] for improved nullable reference type support.
