Georgia EPD-IT Guard Clauses Library

This package was created by Georgia EPD-IT to provide simple guard clause methods for our web applications.

This package was inspired by the great GuardClauses package by Steve Smith, which has a lot more options and extensibility.

How to install

To install, search for "GaEpd.GuardClauses" in the NuGet package manager or run the following command:

dotnet add package GaEpd.GuardClauses

How to use

Guard clauses simplify checking for invalid input parameters.

Example usage:

public class SomeClass
{
    private readonly string _name;

    public SomeClass(string name)
    {
        _name = Guard.NotNullOrWhiteSpace(name);
    }
}

Each clause returns the original value if the conditions are met; otherwise, it throws an exception.

• NotNull – ensures a value is not null.
• NotNullOrWhiteSpace – ensures a string is not null, empty, or whitespace.
• ValidLength – ensures a string has a length between the specified minimum and maximum (inclusive).
• NotNegative – ensures an integer is not negative.
• Positive – ensures an integer is not zero or negative.
• RegexMatch – ensures a string matches the provided regex pattern.
