Pick.Net.Utilites

Various helper classes for C#.

Abstract collection classes

Abstract classes is designed to serve as a base class for creating read-only collections. Methods that modify the collection (i.e. Add, Clear, and Remove) will throw a NotSupportedException.

public class SingleItemCollection(string item) : AbstractReadOnlyCollection<string>
{
	public override int Count => 1;

	public override IEnumerator<string> GetEnumerator()
	{
		yield return item;
	}
}

var collection = new SimpleCollection("test");
var array = collection.ToArray();
// [ "test" ]
((ICollection<T>)collection).Add("another item")
// throws a NotSupportedException

Map

A dictionary-like collection with that allows covariance of the value type parameter and returns null instead of throwing a KeyNotFound exception when accessing a key not in the collection. Only supports reference type values.

var map = new Map<string, string>
{
	{ "key1", "value1" },
	{ "key2", "value2" },
	{ "key3", "value3" }
};

var value1 = map["key1"];
// "value1"
var value4 = map["key4"];
// null

IReadOnlyMap<string, object> objectMap = map;
var value2 = objectMap["key2"];
// "value2"

StringDictionary

A string-keyed dictionary that allows char spans to be used to get values

var map = new StringDictionary<object>
{
	{ "key1", "value1" },
	{ "key2", "value2" },
	{ "key3", "value3" }
};

ReadOnlySpan<char> keys = "key1;key2;key3";

var value1 = map[keys[..4]];
// "value1"
var value2 = map[keys[5..^5]];
// "value2"
var value3 = map[keys[^4..]];
// "value3"

DelegateHelper

Shortcuts for MethodInfo.CreateDelegate for System.Action and System.Func delegates.

Action<object> handler = method.CreateAction<object>();
Func<int, string, bool> handler = method.CreateFunc<int, string, bool>();

Get delegate parameter and return types

ImmutableArray<Type> types = DelegateHelper.GetParameterTypes<Action<string, int>>();
// [ typeof(string), typeof(int) ]
Type types = DelegateHelper.GetReturnType<Func<string>>();
// typeof(string)

Atomic Values

Value type wrappers for int, uint, long, ulong, float and double that use the System.Threading.Interlocked class to perform atomic operations. e.g.

private int value;

void DoSomething()
{
	var next = Interlocked.Increment(ref value);
	var old = Interlocked.Exchange(ref value, 5);
	if (Interlocked.CompareExchange(ref value, 0, 5) == 5)
	{
		...
	}
}

Can be simplified to

private AtomicInt32 value;

void DoSomething()
{
	var next = value.Increment();
	var old = value.Set(5);
	if (value.TrySet(0, 5))
	{
		...
	}
}
