Introduction

Welcome to Wolfgang.Extensions.IComparable!

Overview

Wolfgang.Extensions.IComparable is a lightweight .NET library that provides extension methods for types implementing the IComparable<T> interface. It simplifies common comparison operations, making range checks read the way you'd say them — value.IsBetween(low, high) instead of value.CompareTo(low) > 0 && value.CompareTo(high) < 0.

Why Use This Library?

Without the library, range checks are verbose and easy to get wrong:

// Without Wolfgang.Extensions.IComparable
if (value.CompareTo(min) >= 0 && value.CompareTo(max) <= 0)
{
    // Value is in range
}

// With Wolfgang.Extensions.IComparable
if (value.IsInRange(min, max))
{
    // Value is in range — much clearer
}

Key Features

  • IsBetween — strict (exclusive) range check: value > lower && value < upper
  • IsInRange — inclusive range check: value >= lower && value <= upper
  • Type-safe — works with any type that implements IComparable<T>
  • Zero dependencies — pure .NET Standard 2.0 library
  • Multi-target — runs on .NET Framework 4.6.2+, .NET Standard 2.0+, and .NET 8.0+

Available Extension Methods

IsBetween

Determines if a value is strictly between two bounds (exclusive):

int value = 5;
bool result = value.IsBetween(1, 10); // true — 5 > 1 AND 5 < 10

IsInRange

Determines if a value is within the range of two bounds (inclusive):

int value = 5;
bool result = value.IsInRange(5, 10); // true — 5 >= 5 AND 5 <= 10

Supported Types

Any type implementing IComparable<T> works, including:

  • Numeric types — int, double, decimal, float, long, etc.
  • Date/time types — DateTime, DateTimeOffset, TimeSpan
  • string and char
  • Custom types that implement IComparable<T>
