This package contains a pair of IEnumerable extension methods named WhereNotNull(). The method skips all null elements from a sequence. This is useful for projects that have nullable reference types enabled because it converts IEnumerable<T?> into IEnumerable<T> .

How to use:

For nullable reference types:

using Baksteen.Extensions.WhereNotNull;
var seq = new string?[] { "one", null, "two", null, null, "three", null, null, null }
var result = seq.WhereNotNull();
// the result is IEnumerable<string> { "one", "two", "three" }

For nullable value types:

using Baksteen.Extensions.WhereNotNull;
var seq = new int?[] { 1, null, 2, null, null, 3, null, null, null }
var result = seq.WhereNotNull();
// the result is IEnumerable<int> { 1, 2, 3 }
