CollectionsEx

Useful extensions for C# collections.

Examples

#AddRange

add range to collection, using enumerable

var col = new LinkedList<int>();
col.AddRange(new List<int>() { 0, 1, 2, 3 });
col.Should().HaveCount(4).And.Equal(0, 1, 2, 3);

add range to collection, using params

var col = new LinkedList<int>();
col.AddRange(0, 1, 2, 3);
col.Should().HaveCount(4).And.Equal(0, 1, 2, 3);

#ForEach

iteration

var col = new string[] { "foo", "bar" };

col.ForEach((x) =>
{
    x.Should().NotBeNullOrEmpty();
});

iteration with index

var col = new int[] { 0, 1, 2, 3, 4, 5 };

col.ForEach((x, i) =>
{
    x.Should().Be(i);
});

iteration of dictionary

var dict = new Dictionary<string, int>()
{
    { "foo", 1 },
    { "bar", 2 }
};

dict.ForEach((key, value) =>
{
    key.Should().NotBeNullOrEmpty();
    value.Should().BeGreaterThan(0);
});

#IsNullOrEmpty

int[] arr = null;
arr.IsNullOrEmpty().Should().BeTrue();

var list = new List<int>();
list.IsNullOrEmpty().Should().BeTrue();

#NotNullOrEmpty

int[] arr = new int[] { 0, 1, 2, 3 };
arr.NotNullOrEmpty().Should().BeTrue();

var list = new List<int>() { 0, 1, 2, 3 };
list.NotNullOrEmpty().Should().BeTrue();
