Object extension methods

Overview

SwissArmyKnife adds the following extension methods to object:

• IsAnyOf()

IsAnyOf()

The IsAnyOf() extension method makes comparing objects to multiple values a lot easier and readable. Without this you have to write a lot more code, for example:

var example = 1;

if (example == 1 || example == 2 || example == 3)
{
    // do something
}

With IsAnyOf() you can just do the following:

var example = 1;

if (example.IsAnyOf(1, 2, 3))
{
    // do something
}

It works for any object type:

var example = "lorem";
if (example.IsAnyOf("lorem", "ipsum", "dolor"))
{
    // do something
}

And also on enums:

public enum State
{
    Open,
    Closed,
    Faulted
}

var example = State.Open;
if (example.IsAnyOf(State.Closed, State.Faulted))
{
    // PANIC!
}

Passing IEnumerable<T> implementations like an array or a List<T> is also supported:

var example = "lorem";
if (example.IsAnyOf(new [] { "lorem", "ipsum", "dolor" }))
{
    // do something
}

var example = "lorem";
if (example.IsAnyOf(new List<string>() { "lorem", "ipsum", "dolor" }))
{
    // do something
}
