ThrowIfArgument

NuGet Status NuGet

This is just another guard clause library for validating your arguments, but I enjoy the way using this API reads quite fluently. If you're like me, then you've been recreating a library of guard clauses from company to company. I finally got tired and uploaded my own version of a guard clause library.

This library is very similar to Guard Clauses, which I highly recommend checking out. It is well reviewed and has active support.

NuGet Installation

Install the ThrowIfArgument NuGet package:

dotnet add package ThrowIfArgument

Supported frameworks

  • .NET 8
  • .NET 10

Versions 1.x of the package also support .NET 6 and .NET 7.

Usage

public void HelloWorld(FooBar fooBar)
{
    ThrowIf.Argument.IsNull(fooBar);
    
    Console.WriteLine($"The narwhal bacons at {fooBar.BaconsAt}");
}

Extensibility

If you feel the package is missing a feature, you can extend with your own features:

public static class ThrowIfArgumentExtensions
{
    public static string StartsWithThunderclap
    (
        this IThrowIfBuilder builder,
        string argument,
        string? message = null,
        [CallerArgumentExpression("argument")] string? argumentName = null
    )
    {
        if (!argument.StartsWith("thunderclap", StringComparison.OrdinalIgnoreCase))
        {  
            return argument;
        }
        
        throw new ArgumentException(
            string.IsNullOrWhiteSpace(message)
                ? $"Cannot start with 'thunderclap'."
                : message,
            argumentName);        
    }
}

Ping me if you want any new features added to the library ❤️
