System.Extensions

Collection of extension method for the BCL to ease their usage. Please feel free to submit bits that are not yet included.

Examples

String

     var stringValue = "text";

    _ = stringValue.IsNullOrEmpty();
    _ = stringValue.IsNullOrWhiteSpace();

    _ = stringValue.HasValue();
    _ = stringValue.HasActualValue();

    _ = "{0} {1}".FormatWith(1, 2);

Numeric types

    // Int, uint, long, ulong, byte
    var number = 123;

    _ = intValue.Clamp(0, 100);
    _ = intValue.ToBool(); // each type has its revers bool to number.

Double

    var doubleValue = 12.34;

    _ = doubleValue.Clamp(0, 100);
    _ = doubleValue.IsInfinity();
    _ = doubleValue.IsNegativeInfinity();
    _ = doubleValue.IsPositiveInfinity();
    _ = doubleValue.IsNaN();
    _ = doubleValue.IsEqual(34.12,tolerance: 0.1); //two NaNs are also evaluated as equals

Collection access

    var collection = new[] {1, 2, 3};
    
    _ = collection.HasIndex(4);
    _ = collection.AtIndexOrDefault(4);
    _ = collection.AtIndexOrFallback(4, -1);
    _ = collection.IsEmpty();

    var directory = new Dictionary<int, int>();

    _ = directory.AtKeyOrFallback(4, -1);

Iterators

    // Extensions for IList<T>, IEnumerable<T> and Enumerable

    var collection = new[] {1, 2, 3};

    collection.For((index, value) => {});
    collection.ForEach(value => {});

    _ = collection.SelectWithIndex((index, value) => value);
    _ = collection.SelectTypeOf<double>();

    var secondCollection = new[] {4, 5};

    _ = collection.Append(secondCollection);
